Description
"""""""""""
Define a computation that calculates a set of quantities related to the
POD descriptors of the atoms in a group. These computes are used
primarily for calculating the dependence of energy and force components
on the linear coefficients in the :doc:`pod pair_style
<pair_pod>`, which is useful when training a POD potential to match
target data. POD descriptors of an atom are characterized by the
radial and angular distribution of neighbor atoms. The detailed
mathematical definition is given in the papers by :ref:`(Nguyen and Rohskopf) <Nguyen20222>`,
:ref:`(Nguyen2023) <Nguyen20232>`, :ref:`(Nguyen2024) <Nguyen20242>`, and :ref:`(Nguyen and Sema) <Nguyen20243>`.
Compute *pod/atom* calculates the per-atom POD descriptors.
Compute *podd/atom* calculates derivatives of the per-atom POD descriptors with respect to atom positions.
Compute *pod/ldd* calculates the per-atom POD descriptors and their derivatives with respect to atom positions.

(PES) of the system can be expressed as a many-body expansion of the

POD potential is expressed as :math:`E(\boldsymbol R, \boldsymbol Z) =

where :math:`V^{(1)}` is the one-body potential often used for
representing external field or energy of isolated elements, and the
higher-body potentials :math:`V^{(2)}, V^{(3)}, \ldots` are symmetric,
uniquely defined, and zero if two or more indices take identical values.
The superscript on each potential denotes its body order. Each *q*-body
potential :math:`V^{(q)}` depends on :math:`\boldsymbol \mu^{(q)}` which
are sets of parameters to fit the PES. Note that :math:`\boldsymbol \mu`
is a collection of all potential parameters :math:`\boldsymbol
\mu^{(1)}`, :math:`\boldsymbol \mu^{(2)}`, :math:`\boldsymbol
\mu^{(3)}`, etc, and that :math:`\boldsymbol \eta` is a set of
hyper-parameters such as inner cut-off radius :math:`r_{\rm in}` and
outer cut-off radius :math:`r_{\rm cut}`.
Interatomic potentials rely on parameters to learn relationship between
atomic environments and interactions. Since interatomic potentials are
approximations by nature, their parameters need to be set to some
reference values or fitted against data by necessity. Typically,
potential fitting finds optimal parameters, :math:`\boldsymbol \mu^*`,
to minimize a certain loss function of the predicted quantities and
data. Since the fitted potential depends on the data set used to fit it,
different data sets will yield different optimal parameters and thus
different fitted potentials. When fitting the same functional form on
*Q* different data sets, we would obtain *Q* different optimized
potentials, :math:`E(\boldsymbol R,\boldsymbol Z, \boldsymbol \eta,
\boldsymbol \mu_q^*), 1 \le q \le Q`. Consequently, there exist many
different sets of optimized parameters for empirical interatomic
potentials.
Instead of optimizing the potential parameters, inspired by the reduced
basis method :ref:`(Grepl) <Grepl20072>` for parameterized partial
differential equations, we view the parameterized PES as a parametric
manifold of potential energies
.. math::
\mathcal{M} = \{E(\boldsymbol R, \boldsymbol Z, \boldsymbol \eta, \boldsymbol \mu) \ | \ \boldsymbol \mu \in \Omega^{\boldsymbol \mu} \}
where :math:`\Omega^{\boldsymbol \mu}` is a parameter domain in which
:math:`\boldsymbol \mu` resides. The parametric manifold
:math:`\mathcal{M}` contains potential energy surfaces for all values of
:math:`\boldsymbol \mu \in \Omega^{\boldsymbol \mu}`. Therefore, the
parametric manifold yields a much richer and more transferable atomic
representation than any particular individual PES :math:`E(\boldsymbol
R, \boldsymbol Z, \boldsymbol \eta, \boldsymbol \mu^*)`.
We propose specific forms of the parameterized potentials for one-body,
two-body, and three-body interactions. We apply the Karhunen-Loeve
expansion to snapshots of the parameterized potentials to obtain sets of
orthogonal basis functions. These basis functions are aggregated
according to the chemical elements of atoms, thus leading to
multi-element proper orthogonal descriptors.
Proper Orthogonal Descriptors
"""""""""""""""""""""""""""""
Proper orthogonal descriptors are finger prints characterizing the
radial and angular distribution of a system of atoms. The detailed
mathematical definition is given in the paper by Nguyen and Rohskopf
:ref:`(Nguyen) <Nguyen20222>`.
The descriptors for the one-body interaction are used to capture energy
of isolated elements and defined as follows
.. math::
D_{ip}^{(1)} = \left\{
\begin{array}{ll}
1, & \mbox{if } Z_i = p \\
0, & \mbox{if } Z_i \neq p
\end{array}
\right.
for :math:`1 \le i \le N, 1 \le p \le N_{\rm e}`. The number of one-body
descriptors per atom is equal to the number of elements. The one-body
descriptors are independent of atom positions, but dependent on atom
types. The one-body descriptors are active only when the keyword
*onebody* is set to 1.
We adopt the usual assumption that the direct interaction between two
atoms vanishes smoothly when their distance is greater than the outer
cutoff distance :math:`r_{\rm cut}`. Furthermore, we assume that two
atoms can not get closer than the inner cutoff distance :math:`r_{\rm
in}` due to the Pauli repulsion principle. Let :math:`r \in (r_{\rm in},
r_{\rm cut})`, we introduce the following parameterized radial functions
.. math::
\phi(r, r_{\rm in}, r_{\rm cut}, \alpha, \beta) = \frac{\sin (\alpha \pi x) }{r - r_{\rm in}}, \qquad \varphi(r, \gamma) = \frac{1}{r^\gamma} ,
where the scaled distance function :math:`x` is defined below to enrich the two-body manifold
.. math::
x(r, r_{\rm in}, r_{\rm cut}, \beta) = \frac{e^{-\beta(r - r_{\rm in})/(r_{\rm cut} - r_{\rm in})} - 1}{e^{-\beta} - 1} .
We introduce the following function as a convex combination of the two functions
.. math::
\psi(r, r_{\rm in}, r_{\rm cut}, \alpha, \beta, \gamma, \kappa) = \kappa \phi(r, r_{\rm in}, r_{\rm cut}, \alpha, \beta) + (1- \kappa) \varphi(r, \gamma) .
We see that :math:`\psi` is a function of distance :math:`r`, cut-off
distances :math:`r_{\rm in}` and :math:`r_{\rm cut}`, and parameters
:math:`\alpha, \beta, \gamma, \kappa`. Together these parameters allow
the function :math:`\psi` to characterize a diverse spectrum of two-body
interactions within the cut-off interval :math:`(r_{\rm in}, r_{\rm
cut})`.
Next, we introduce the following parameterized potential
.. math::
W^{(2)}(r_{ij}, \boldsymbol \eta, \boldsymbol \mu^{(2)}) = f_{\rm c}(r_{ij}, \boldsymbol \eta) \psi(r_{ij}, \boldsymbol \eta, \boldsymbol \mu^{(2)})
where :math:`\eta_1 = r_{\rm in}, \eta_2 = r_{\rm cut}, \mu_1^{(2)} =
\alpha, \mu_2^{(2)} = \beta, \mu_3^{(2)} = \gamma`, and
:math:`\mu_4^{(2)} = \kappa`. Here the cut-off function :math:`f_{\rm
c}(r_{ij}, \boldsymbol \eta)` proposed in [refs] is used to ensure the
smooth vanishing of the potential and its derivative for :math:`r_{ij}
\ge r_{\rm cut}`:
.. math::
f_{\rm c}(r_{ij}, r_{\rm in}, r_{\rm cut}) = \exp \left(1 -\frac{1}{\sqrt{\left(1 - \frac{(r-r_{\rm in})^3}{(r_{\rm cut} - r_{\rm in})^3} \right)^2 + 10^{-6}}} \right)
Based on the parameterized potential, we form a set of snapshots as
follows. We assume that we are given :math:`N_{\rm s}` parameter tuples
:math:`\boldsymbol \mu^{(2)}_\ell, 1 \le \ell \le N_{\rm s}`. We
introduce the following set of snapshots on :math:`(r_{\rm in}, r_{\rm
cut})`:
.. math::
\xi_\ell(r_{ij}, \boldsymbol \eta) = W^{(2)}(r_{ij}, \boldsymbol \eta, \boldsymbol \mu^{(2)}_\ell), \quad \ell = 1, \ldots, N_{\rm s} .
To ensure adequate sampling of the PES for different parameters, we
choose :math:`N_{\rm s}` parameter points :math:`\boldsymbol
\mu^{(2)}_\ell = (\alpha_\ell, \beta_\ell, \gamma_\ell, \kappa_\ell), 1
\le \ell \le N_{\rm s}` as follows. The parameters :math:`\alpha \in [1,
N_\alpha]` and :math:`\gamma \in [1, N_\gamma]` are integers, where
:math:`N_\alpha` and :math:`N_\gamma` are the highest degrees for
:math:`\alpha` and :math:`\gamma`, respectively. We next choose
:math:`N_\beta` different values of :math:`\beta` in the interval
:math:`[\beta_{\min}, \beta_{\max}]`, where :math:`\beta_{\min} = 0` and
:math:`\beta_{\max} = 4`. The parameter :math:`\kappa` can be set either
0 or 1. Hence, the total number of parameter points is :math:`N_{\rm s}
= N_\alpha N_\beta + N_\gamma`. Although :math:`N_\alpha, N_\beta,
N_\gamma` can be chosen conservatively large, we find that
:math:`N_\alpha = 6, N_\beta = 3, N_\gamma = 8` are adequate for most
problems. Note that :math:`N_\alpha` and :math:`N_\gamma` correspond to
*bessel_polynomial_degree* and *inverse_polynomial_degree*,
respectively.
We employ the Karhunen-Loeve (KL) expansion to generate an orthogonal
basis set which is known to be optimal for representation of the
snapshot family :math:`\{\xi_\ell\}_{\ell=1}^{N_{\rm s}}`. The two-body
orthogonal basis functions are computed as follows
.. math::
U^{(2)}_m(r_{ij}, \boldsymbol \eta) = \sum_{\ell = 1}^{N_{\rm s}} A_{\ell m}(\boldsymbol \eta) \, \xi_\ell(r_{ij}, \boldsymbol \eta), \qquad m = 1, \ldots, N_{\rm 2b} ,
where the matrix :math:`\boldsymbol A \in \mathbb{R}^{N_{\rm s} \times
N_{\rm s}}` consists of eigenvectors of the eigenvalue problem
.. math::
\boldsymbol C \boldsymbol a = \lambda \boldsymbol a
with the entries of :math:`\boldsymbol C \in \mathbb{R}^{N_{\rm s} \times N_{\rm s}}` being given by
.. math::
C_{ij} = \frac{1}{N_{\rm s}} \int_{r_{\rm in}}^{r_{\rm cut}} \xi_i(x, \boldsymbol \eta) \xi_j(x, \boldsymbol \eta) dx, \quad 1 \le i, j \le N_{\rm s}
Note that the eigenvalues :math:`\lambda_\ell, 1 \le \ell \le N_{\rm
s}`, are ordered such that :math:`\lambda_1 \ge \lambda_2 \ge \ldots \ge
\lambda_{N_{\rm s}}`, and that the matrix :math:`\boldsymbol A` is
pe-computed and stored for any given :math:`\boldsymbol \eta`. Owing to
the rapid convergence of the KL expansion, only a small number of
orthogonal basis functions is needed to obtain accurate
approximation. The value of :math:`N_{\rm 2b}` corresponds to
*twobody_number_radial_basis_functions*.
The two-body proper orthogonal descriptors at each atom *i* are computed
by summing the orthogonal basis functions over the neighbors of atom *i*
and numerating on the atom types as follows
.. math::
D^{(2)}_{im l(p, q) }(\boldsymbol \eta) = \left\{
\begin{array}{ll}
\displaystyle \sum_{\{j | Z_j = q\}} U^{(2)}_m(r_{ij}, \boldsymbol \eta), & \mbox{if } Z_i = p \\
0, & \mbox{if } Z_i \neq p
\end{array}
\right.
for :math:`1 \le i \le N, 1 \le m \le N_{\rm 2b}, 1 \le q, p \le N_{\rm
e}`. Here :math:`l(p,q)` is a symmetric index mapping such that
.. math::
l(p,q) = \left\{
\begin{array}{ll}
q + (p-1) N_{\rm e} - p(p-1)/2, & \mbox{if } q \ge p \\
p + (q-1) N_{\rm e} - q(q-1)/2, & \mbox{if } q < p .
\end{array}
\right.
The number of two-body descriptors per atom is thus :math:`N_{\rm 2b}
N_{\rm e}(N_{\rm e}+1)/2`.
It is important to note that the orthogonal basis functions do not
depend on the atomic numbers :math:`Z_i` and :math:`Z_j`. Therefore, the
cost of evaluating the basis functions and their derivatives with
respect to :math:`r_{ij}` is independent of the number of elements
:math:`N_{\rm e}`. Consequently, even though the two-body proper
orthogonal descriptors depend on :math:`\boldsymbol Z`, their
computational complexity is independent of :math:`N_{\rm e}`.
In order to provide proper orthogonal descriptors for three-body
interactions, we need to introduce a three-body parameterized
potential. In particular, the three-body potential is defined as a
product of radial and angular functions as follows
.. math::
W^{(3)}(r_{ij}, r_{ik}, \theta_{ijk}, \boldsymbol \eta, \boldsymbol \mu^{(3)}) = \psi(r_{ij}, r_{\rm min}, r_{\rm max}, \alpha, \beta, \gamma, \kappa) f_{\rm c}(r_{ij}, r_{\rm min}, r_{\rm max}) \\
\psi(r_{ik}, r_{\rm min}, r_{\rm max}, \alpha, \beta, \gamma, \kappa) f_{\rm c}(r_{ik}, r_{\rm min}, r_{\rm max}) \\
\cos (\sigma \theta_{ijk} + \zeta)
where :math:`\sigma` is the periodic multiplicity, :math:`\zeta` is the
equilibrium angle, :math:`\boldsymbol \mu^{(3)} = (\alpha, \beta,
\gamma, \kappa, \sigma, \zeta)`. The three-body potential provides an
angular fingerprint of the atomic environment through the bond angles
:math:`\theta_{ijk}` formed with each pair of neighbors :math:`j` and
:math:`k`. Compared to the two-body potential, the three-body potential
has two extra parameters :math:`(\sigma, \zeta)` associated with the
angular component.
Let :math:`\boldsymbol \varrho = (\alpha, \beta, \gamma, \kappa)`. We
assume that we are given :math:`L_{\rm r}` parameter tuples
:math:`\boldsymbol \varrho_\ell, 1 \le \ell \le L_{\rm r}`. We
introduce the following set of snapshots on :math:`(r_{\min},
r_{\max})`:
.. math::
\zeta_\ell(r_{ij}, r_{\rm min}, r_{\rm max} ) = \psi(r_{ij}, r_{\rm min}, r_{\rm max}, \boldsymbol \varrho_\ell) f_{\rm c}(r_{ij}, r_{\rm min}, r_{\rm max}), \quad 1 \le \ell \le L_{\rm r} .
We apply the Karhunen-Loeve (KL) expansion to this set of snapshots to
obtain orthogonal basis functions as follows
.. math::
U^{r}_m(r_{ij}, r_{\rm min}, r_{\rm max} ) = \sum_{\ell = 1}^{L_{\rm r}} A_{\ell m} \, \zeta_\ell(r_{ij}, r_{\rm min}, r_{\rm max} ), \qquad m = 1, \ldots, N_{\rm r} ,
where the matrix :math:`\boldsymbol A \in \mathbb{R}^{L_{\rm r} \times L_{\rm r}}` consists
of eigenvectors of the eigenvalue problem. For the parameterized angular function,
we consider angular basis functions
.. math::
U^{a}_n(\theta_{ijk}) = \cos ((n-1) \theta_{ijk}), \qquad n = 1,\ldots, N_{\rm a},
where :math:`N_{\rm a}` is the number of angular basis functions. The orthogonal
basis functions for the parameterized potential are computed as follows
.. math::
U^{(3)}_{mn}(r_{ij}, r_{ik}, \theta_{ijk}, \boldsymbol \eta) = U^{r}_m(r_{ij}, \boldsymbol \eta) U^{r}_m(r_{ik}, \boldsymbol \eta) U^{a}_n(\theta_{ijk}),
for :math:`1 \le m \le N_{\rm r}, 1 \le n \le N_{\rm a}`. The number of three-body
orthogonal basis functions is equal to :math:`N_{\rm 3b} = N_{\rm r} N_{\rm a}` and
independent of the number of elements. The value of :math:`N_{\rm r}` corresponds to
*threebody_number_radial_basis_functions*, while that of :math:`N_{\rm a}` to
*threebody_number_angular_basis_functions*.
The three-body proper orthogonal descriptors at each atom *i*
are obtained by summing over the neighbors *j* and *k* of atom *i* as
.. math::
D^{(3)}_{imn \ell(p, q, s)}(\boldsymbol \eta) = \left\{
\begin{array}{ll}
\displaystyle \sum_{\{j | Z_j = q\}} \sum_{\{k | Z_k = s\}} U^{(3)}_{mn}(r_{ij}, r_{ik}, \theta_{ijk}, \boldsymbol \eta), & \mbox{if } Z_i = p \\
0, & \mbox{if } Z_i \neq p
\end{array}
\right.
for :math:`1 \le i \le N, 1 \le m \le N_{\rm r}, 1 \le n \le N_{\rm a}, 1 \le q, p, s \le N_{\rm e}`,
where
.. math::
\ell(p,q,s) = \left\{
\begin{array}{ll}
s + (q-1) N_{\rm e} - q(q-1)/2 + (p-1)N_{\rm e}(1+N_{\rm e})/2 , & \mbox{if } s \ge q \\
q + (s-1) N_{\rm e} - s(s-1)/2 + (p-1)N_{\rm e}(1+N_{\rm e})/2, & \mbox{if } s < q .
\end{array}
\right.
The number of three-body descriptors per atom is thus :math:`N_{\rm 3b} N_{\rm e}^2(N_{\rm e}+1)/2`.
While the number of three-body PODs is cubic function of the number of elements,
the computational complexity of the three-body PODs is independent of the number of elements.
Four-Body SNAP Descriptors
""""""""""""""""""""""""""
In addition to the proper orthogonal descriptors described above, we also employ
the spectral neighbor analysis potential (SNAP) descriptors. SNAP uses bispectrum components
to characterize the local neighborhood of each atom in a very general way. The mathematical definition
of the bispectrum calculation and its derivatives w.r.t. atom positions is described in
:doc:`compute snap <compute_sna_atom>`. In SNAP, the
total energy is decomposed into a sum over atom energies. The energy of
atom *i* is expressed as a weighted sum over bispectrum components.
.. math::
E_i^{\rm SNAP} = \sum_{k=1}^{N_{\rm 4b}} \sum_{p=1}^{N_{\rm e}} c_{kp}^{(4)} D_{ikp}^{(4)}
where the SNAP descriptors are related to the bispectrum components by
.. math::
D^{(4)}_{ikp} = \left\{
\begin{array}{ll}
\displaystyle B_{ik}, & \mbox{if } Z_i = p \\
0, & \mbox{if } Z_i \neq p
\end{array}
\right.
Here :math:`B_{ik}` is the *k*\ -th bispectrum component of atom *i*. The number of
bispectrum components :math:`N_{\rm 4b}` depends on the value of *fourbody_snap_twojmax* :math:`= 2 J_{\rm max}`
and *fourbody_snap_chemflag*. If *fourbody_snap_chemflag* = 0
then :math:`N_{\rm 4b} = (J_{\rm max}+1)(J_{\rm max}+2)(J_{\rm max}+1.5)/3`.
If *fourbody_snap_chemflag* = 1 then :math:`N_{\rm 4b} = N_{\rm e}^3 (J_{\rm max}+1)(J_{\rm max}+2)(J_{\rm max}+1.5)/3`.
The bispectrum calculation is described in more detail in :doc:`compute sna/atom <compute_sna_atom>`.
Linear Proper Orthogonal Descriptor Potentials
""""""""""""""""""""""""""""""""""""""""""""""
The proper orthogonal descriptors and SNAP descriptors are used to define the atomic energies
in the following expansion
.. math::
E_{i}(\boldsymbol \eta) = \sum_{p=1}^{N_{\rm e}} c^{(1)}_p D^{(1)}_{ip} + \sum_{m=1}^{N_{\rm 2b}} \sum_{l=1}^{N_{\rm e}(N_{\rm e}+1)/2} c^{(2)}_{ml} D^{(2)}_{iml}(\boldsymbol \eta) + \sum_{m=1}^{N_{\rm r}} \sum_{n=1}^{N_{\rm a}} \sum_{\ell=1}^{N_{\rm e}^2(N_{\rm e}+1)/2} c^{(3)}_{mn\ell} D^{(3)}_{imn\ell}(\boldsymbol \eta) + \sum_{k=1}^{N_{\rm 4b}} \sum_{p=1}^{N_{\rm e}} c_{kp}^{(4)} D_{ikp}^{(4)}(\boldsymbol \eta),
where :math:`D^{(1)}_{ip}, D^{(2)}_{iml}, D^{(3)}_{imn\ell}, D^{(4)}_{ikp}` are the one-body, two-body, three-body, four-body descriptors,
respectively, and :math:`c^{(1)}_p, c^{(2)}_{ml}, c^{(3)}_{mn\ell}, c^{(4)}_{kp}` are their respective expansion
coefficients. In a more compact notation that implies summation over descriptor indices
the atomic energies can be written as
.. math::
E_i(\boldsymbol \eta) = \sum_{m=1}^{N_{\rm e}} c^{(1)}_m D^{(1)}_{im} + \sum_{m=1}^{N_{\rm d}^{(2)}} c^{(2)}_k D^{(2)}_{im} + \sum_{m=1}^{N_{\rm d}^{(3)}} c^{(3)}_m D^{(3)}_{im} + \sum_{m=1}^{N_{\rm d}^{(4)}} c^{(4)}_m D^{(4)}_{im}
where :math:`N_{\rm d}^{(2)} = N_{\rm 2b} N_{\rm e} (N_{\rm e}+1)/2`,
:math:`N_{\rm d}^{(3)} = N_{\rm 3b} N_{\rm e}^2 (N_{\rm e}+1)/2`, and
:math:`N_{\rm d}^{(4)} = N_{\rm 4b} N_{\rm e}` are
the number of two-body, three-body, and four-body descriptors, respectively.
The potential energy is then obtained by summing local atomic energies :math:`E_i`
for all atoms :math:`i` in the system
.. math::
E(\boldsymbol \eta) = \sum_{i}^N E_{i}(\boldsymbol \eta)
Because the descriptors are one-body, two-body, and three-body terms,
the resulting POD potential is a three-body PES. We can express the potential
energy as a linear combination of the global descriptors as follows
.. math::
E(\boldsymbol \eta) = \sum_{m=1}^{N_{\rm e}} c^{(1)}_m d^{(1)}_{m} + \sum_{m=1}^{N_{\rm d}^{(2)}} c^{(2)}_m d^{(2)}_{m} + \sum_{m=1}^{N_{\rm d}^{(3)}} c^{(3)}_m d^{(3)}_{m} + \sum_{m=1}^{N_{\rm d}^{(4)}} c^{(4)}_m d^{(4)}_{m}
where the global descriptors are given by
.. math::
d_{m}^{(1)}(\boldsymbol \eta) = \sum_{i=1}^N D_{im}^{(1)}(\boldsymbol \eta), \quad d_{m}^{(2)}(\boldsymbol \eta) = \sum_{i=1}^N D_{im}^{(2)}(\boldsymbol \eta), \quad d_{m}^{(3)}(\boldsymbol \eta) = \sum_{i=1}^N D_{im}^{(3)}(\boldsymbol \eta), \quad d_{m}^{(4)}(\boldsymbol \eta) = \sum_{i=1}^N D_{im}^{(4)}(\boldsymbol \eta)
Hence, we obtain the atomic forces as
.. math::
\boldsymbol F = -\nabla E(\boldsymbol \eta) = - \sum_{m=1}^{N_{\rm d}^{(2)}} c^{(2)}_m \nabla d_m^{(2)} - \sum_{m=1}^{N_{\rm d}^{(3)}} c^{(3)}_m \nabla d_m^{(3)} - \sum_{m=1}^{N_{\rm d}^{(4)}} c^{(4)}_m \nabla d_m^{(4)}
where :math:`\nabla d_m^{(2)}`, :math:`\nabla d_m^{(3)}` and :math:`\nabla d_m^{(4)}` are derivatives of the two-body
three-body, and four-body global descriptors with respect to atom positions, respectively.
Note that since the first-body global descriptors are constant, their derivatives are zero.
Quadratic Proper Orthogonal Descriptor Potentials
"""""""""""""""""""""""""""""""""""""""""""""""""
We recall two-body PODs :math:`D^{(2)}_{ik}, 1 \le k \le N_{\rm d}^{(2)}`,
and three-body PODs :math:`D^{(3)}_{im}, 1 \le m \le N_{\rm d}^{(3)}`,
with :math:`N_{\rm d}^{(2)} = N_{\rm 2b} N_{\rm e} (N_{\rm e}+1)/2` and
:math:`N_{\rm d}^{(3)} = N_{\rm 3b} N_{\rm e}^2 (N_{\rm e}+1)/2` being
the number of descriptors per atom for the two-body PODs and three-body PODs,
respectively. We employ them to define a new set of atomic descriptors as follows
.. math::
D^{(2*3)}_{ikm} = \frac{1}{2N}\left( D^{(2)}_{ik} \sum_{j=1}^N D^{(3)}_{jm} + D^{(3)}_{im} \sum_{j=1}^N D^{(2)}_{jk} \right)
for :math:`1 \le i \le N, 1 \le k \le N_{\rm d}^{(2)}, 1 \le m \le N_{\rm d}^{(3)}`.
The new descriptors are four-body because they involve central atom :math:`i` together
with three neighbors :math:`j, k` and :math:`l`. The total number of new descriptors per atom is equal to
.. math::
N_{\rm d}^{(2*3)} = N_{\rm d}^{(2)} * N_{\rm d}^{(3)} = N_{\rm 2b} N_{\rm 3b} N_{\rm e}^3 (N_{\rm e}+1)^2/4 .
The new global descriptors are calculated as
.. math::
d^{(2*3)}_{km} = \sum_{i=1}^N D^{(2*3)}_{ikm} = \left( \sum_{i=1}^N D^{(2)}_{ik} \right) \left( \sum_{i=1}^N D^{(3)}_{im} \right) = d^{(2)}_{k} d^{(3)}_m,
for :math:`1 \le k \le N_{\rm d}^{(2)}, 1 \le m \le N_{\rm d}^{(3)}`. Hence, the gradient
of the new global descriptors with respect to atom positions is calculated as
.. math::
\nabla d^{(2*3)}_{km} = d^{(3)}_m \nabla d^{(2)}_{k} + d^{(2)}_{k} \nabla d^{(3)}_m, \quad 1 \le k \le N_{\rm d}^{(2)}, 1 \le m \le N_{\rm d}^{(3)} .
The quadratic POD potential is defined as a linear combination of the
original and new global descriptors as follows
.. math::
E^{(2*3)} = \sum_{k=1}^{N_{\rm 2d}^{(2*3)}} \sum_{m=1}^{N_{\rm 3d}^{(2*3)}} c^{(2*3)}_{km} d^{(2*3)}_{km} .
It thus follows that
.. math::
E^{(2*3)} = 0.5 \sum_{k=1}^{N_{\rm 2d}^{(2*3)}} \left( \sum_{m=1}^{N_{\rm 3d}^{(2*3)}} c^{(2*3)}_{km} d_m^{(3)} \right) d_k^{(2)} + 0.5 \sum_{m=1}^{N_{\rm 3d}^{(2*3)}} \left( \sum_{k=1}^{N_{\rm 2d}^{(2*3)}} c^{(2*3)}_{km} d_k^{(2)} \right) d_m^{(3)} ,
which is simplified to
.. math::
E^{(2*3)} = 0.5 \sum_{k=1}^{N_{\rm 2d}^{(2*3)}} b_k^{(2)} d_k^{(2)} + 0.5 \sum_{m=1}^{N_{\rm 3d}^{(2*3)}} b_m^{(3)} d_m^{(3)}
where
.. math::
b_k^{(2)} & = \sum_{m=1}^{N_{\rm 3d}^{(2*3)}} c^{(2*3)}_{km} d_m^{(3)}, \quad k = 1,\ldots, N_{\rm 2d}^{(2*3)}, \\
b_m^{(3)} & = \sum_{k=1}^{N_{\rm 2d}^{(2*3)}} c^{(2*3)}_{km} d_k^{(2)}, \quad m = 1,\ldots, N_{\rm 3d}^{(2*3)} .
The quadratic POD potential results in the following atomic forces
.. math::
\boldsymbol F^{(2*3)} = - \sum_{k=1}^{N_{\rm 2d}^{(2*3)}} \sum_{m=1}^{N_{\rm 3d}^{(2*3)}} c^{(2*3)}_{km} \nabla d^{(2*3)}_{km} .
It can be shown that
.. math::
\boldsymbol F^{(2*3)} = - \sum_{k=1}^{N_{\rm 2d}^{(2*3)}} b^{(2)}_k \nabla d_k^{(2)} - \sum_{m=1}^{N_{\rm 3d}^{(2*3)}} b^{(3)}_m \nabla d_m^{(3)} .
The calculation of the atomic forces for the quadratic POD potential
only requires the extra calculation of :math:`b_k^{(2)}` and :math:`b_m^{(3)}` which can be negligible.
As a result, the quadratic POD potential does not increase the computational complexity.
Here :math:`c_m` are trainable coefficients and :math:`\mathcal{D}_{im}(\boldsymbol R_i, \boldsymbol Z_i)`
are per-atom POD descriptors. Summing the per-atom descriptors over :math:`i` yields the
global descriptors :math:`d_m(\boldsymbol R, \boldsymbol Z) = \sum_{i=1}^N \mathcal{D}_{im}(\boldsymbol R_i, \boldsymbol Z_i)`.
It thus follows that :math:`E(\boldsymbol R, \boldsymbol Z) =
\sum_{m=1}^M c_m d_m(\boldsymbol R, \boldsymbol Z)`.
The per-atom POD descriptors include one, two, three, four, five, six, and seven-body
descriptors, which can be specified in the first input file. Furthermore, the per-atom POD descriptors
also depend on the number of environment clusters speciefied in the first input file.

The training procedure is the same for both the linear and quadratic POD
potentials. However, since the quadratic POD potential has a
significantly larger number of the global descriptors, it is more
expensive to train the linear POD potential. This is because the
training of the quadratic POD potential still requires us to calculate
and store the quadratic global descriptors and their
gradient. Furthermore, the quadratic POD potential may require more
training data in order to prevent over-fitting. In order to reduce the
computational cost of fitting the quadratic POD potential and avoid
over-fitting, we can use subsets of two-body and three-body PODs for
constructing the new descriptors.

### POD example for InP
We will fit a potential to the `InP` training data in the `XYZ` directory, which houses `.xyz` files
Please download the training data from [the repo](https://github.com/cesmix-mit/pod-examples/tree/main/JCP2023_InP/XYZ)
Fit POD with
lmp -in InP_fit.pod
This creates `InP_coefficients.pod` for the linear model, which we can use to run MD with
lmp -in InP_mdrun.pod
