Pair style *reaxff* computes the ReaxFF potential of van Duin, Goddard
and co-workers. ReaxFF uses distance-dependent bond-order functions to
represent the contributions of chemical bonding to the potential
energy. There is more than one version of ReaxFF. The version
energy. There is more than one version of ReaxFF. The version
implemented in LAMMPS uses the functional forms documented in the
supplemental information of the following paper:
:ref:`(Chenoweth et al., 2008) <Chenoweth_20082>`. The version integrated
into LAMMPS matches the version of ReaxFF From Summer 2010. For more
technical details about the pair reaxff implementation of ReaxFF, see
the :ref:`(Aktulga) <Aktulga>` paper. The *reaxff* style was initially
implemented as a stand-alone C code and is now converted to C++ and
integrated into LAMMPS as a package.

The *reaxff/kk* style is a Kokkos version of the ReaxFF potential that
is derived from the *reaxff* style. The Kokkos version can run on GPUs
and can also use OpenMP multithreading. For more information about the

and can also use OpenMP multithreading. For more information about the
Kokkos package, see :doc:`Packages details <Packages_details>` and

consideration when using the *reaxff/kk* style is the choice of either
