< p > Set the formula(s) LAMMPS uses to compute pairwise interactions. In
2006-09-22 00:22:34 +08:00
LAMMPS, pair potentials are defined between pairs of atoms that are
within a cutoff distance and the set of active interactions typically
2015-07-30 22:53:28 +08:00
changes over time. See the < a class = "reference internal" href = "bond_style.html" > < em > bond_style< / em > < / a > command to
2006-09-22 00:22:34 +08:00
define potentials between pairs of bonded atoms, which typically
2015-07-30 22:53:28 +08:00
remain in place for the duration of a simulation.< / p >
< p > In LAMMPS, pairwise force fields encompass a variety of interactions,
2006-09-22 00:22:34 +08:00
some of which include many-body effects, e.g. EAM, Stillinger-Weber,
2015-07-30 22:53:28 +08:00
Tersoff, REBO potentials. They are still classified as “ pairwise”
2007-06-20 20:56:17 +08:00
potentials because the set of interacting atoms changes with time
2007-06-25 22:36:36 +08:00
(unlike molecular bonds) and thus a neighbor list is used to find
2015-07-30 22:53:28 +08:00
nearby interacting atoms.< / p >
< p > Hybrid models where specified pairs of atom types interact via
different pair potentials can be setup using the < em > hybrid< / em > pair style.< / p >
< p > The coefficients associated with a pair style are typically set for
2006-09-22 00:22:34 +08:00
each pair of atom types, and are specified by the
2015-07-30 22:53:28 +08:00
< a class = "reference internal" href = "pair_coeff.html" > < em > pair_coeff< / em > < / a > command or read from a file by the
< a class = "reference internal" href = "read_data.html" > < em > read_data< / em > < / a > or < a class = "reference internal" href = "read_restart.html" > < em > read_restart< / em > < / a >
commands.< / p >
< p > The < a class = "reference internal" href = "pair_modify.html" > < em > pair_modify< / em > < / a > command sets options for mixing of
2007-06-25 22:36:36 +08:00
type I-J interaction coefficients and adding energy offsets or tail
corrections to Lennard-Jones potentials. Details on these options as
they pertain to individual potentials are described on the doc page
for the potential. Likewise, info on whether the potential
2015-07-30 22:53:28 +08:00
information is stored in a < a class = "reference internal" href = "write_restart.html" > < em > restart file< / em > < / a > is listed
on the potential doc page.< / p >
< p > In the formulas listed for each pair style, < em > E< / em > is the energy of a
pairwise interaction between two atoms separated by a distance < em > r< / em > .
2006-09-22 00:22:34 +08:00
The force between the atoms is the negative derivative of this
2015-07-30 22:53:28 +08:00
expression.< / p >
< p > If the pair_style command has a cutoff argument, it sets global
2006-09-22 00:22:34 +08:00
cutoffs for all pairs of atom types. The distance(s) can be smaller
2015-07-30 22:53:28 +08:00
or larger than the dimensions of the simulation box.< / p >
< p > Typically, the global cutoff value can be overridden for a specific
pair of atom types by the < a class = "reference internal" href = "pair_coeff.html" > < em > pair_coeff< / em > < / a > command. The
2006-09-22 00:22:34 +08:00
pair style settings (including global cutoffs) can be changed by a
subsequent pair_style command using the same style. This will reset
the cutoffs for all atom type pairs, including those previously set
2015-07-30 22:53:28 +08:00
explicitly by a < a class = "reference internal" href = "pair_coeff.html" > < em > pair_coeff< / em > < / a > command. The exceptions
to this are that pair_style < em > table< / em > and < em > hybrid< / em > settings cannot be
2006-09-22 00:22:34 +08:00
reset. A new pair_style command for these styles will wipe out all
2015-07-30 22:53:28 +08:00
previously specified pair_coeff values.< / p >
< hr class = "docutils" / >
< p > Here is an alphabetic list of pair styles defined in LAMMPS. They are
also given in more compact form in the pair section of < a class = "reference internal" href = "Section_commands.html#cmd-5" > < span > this page< / span > < / a > .< / p >
< p > Click on the style to display the formula it computes, arguments
2014-02-11 04:45:07 +08:00
specified in the pair_style command, and coefficients specified by the
2015-07-30 22:53:28 +08:00
associated < a class = "reference internal" href = "pair_coeff.html" > < em > pair_coeff< / em > < / a > command.< / p >
< p > There are also additional pair styles (not listed here) submitted by
2014-02-11 04:45:07 +08:00
users which are included in the LAMMPS distribution. The list of
these with links to the individual styles are given in the pair
