			<h2>Description</h2>
			<p>The <em>lj/cut/soft</em> style and substyles compute the 12/6 Lennard-Jones
			and Coulomb potential modified by a soft core, in order to avoid
			singularities during free energy calculations when sites are created
			or anihilated <a class="reference internal" href="#beutler"><span class="std std-ref">(Beutler)</span></a>,</p>
			<img alt="_images/pair_lj_soft.jpg" class="align-center" src="_images/pair_lj_soft.jpg" />
			<p>Coulomb interactions are also damped with a soft core at short
			distance,</p>
			<img alt="_images/pair_coul_soft.jpg" class="align-center" src="_images/pair_coul_soft.jpg" />
			<p>In the Coulomb part C is an energy-conversion constant, q_i and q_j
			are the charges on the 2 atoms, and epsilon is the dielectric constant
			which can be set by the <a class="reference internal" href="dielectric.html"><span class="doc">dielectric</span></a> command.</p>
			<p>The coefficient lambda is an activation parameter. When lambda = 1 the
			pair potentiel is identical to a Lennard-Jones term or a Coulomb term
			or a combination of both. When lambda = 0 the interactions are
			deactivated. The transition between these two extrema is smoothed by a
			soft repulsive core in order to avoid singularities in potential
			energy and forces when sites are created or anihilated and can overlap
			<a class="reference internal" href="#beutler"><span class="std std-ref">(Beutler)</span></a>.</p>
			<p>The paratemers n, alpha_LJ and alpha_C are set in the
			<a class="reference internal" href="pair_style.html"><span class="doc">pair_style</span></a> command, before the cutoffs. Usual
			choices for the exponent are n = 2 or n = 1. For the remaining
			coefficients alpha_LJ = 0.5 and alpha_C = 10 Angstrom^2 are
			appropriate choices. Plots of the LJ and Coulomb terms are shown
			below, for lambda ranging from 1 to 0 every 0.1.</p>
			<img alt="_images/lj_soft.jpg" src="_images/lj_soft.jpg" />
			<img alt="_images/coul_soft.jpg" src="_images/coul_soft.jpg" />
			<p>For the <em>lj/cut/coul/cut/soft</em> or <em>lj/cut/coul/long/soft</em> pair styles,
			the following coefficients must be defined for each pair of atoms
			types via the <a class="reference internal" href="pair_coeff.html"><span class="doc">pair_coeff</span></a> command as in the examples
			above, or in the data file or restart files read by the
			<a class="reference internal" href="read_data.html"><span class="doc">read_data</span></a> or <a class="reference internal" href="read_restart.html"><span class="doc">read_restart</span></a>
			commands, or by mixing as described below:</p>
			<ul class="simple">
			<li>epsilon (energy units)</li>
			<li>sigma (distance units)</li>
			<li>lambda (activation parameter between 0 and 1)</li>
			<li>cutoff1 (distance units)</li>
			<li>cutoff2 (distance units)</li>
			</ul>
			<p>The latter two coefficients are optional. If not specified, the global
			LJ and Coulombic cutoffs specified in the pair_style command are used.
			If only one cutoff is specified, it is used as the cutoff for both LJ
			and Coulombic interactions for this type pair. If both coefficients
			are specified, they are used as the LJ and Coulombic cutoffs for this
			type pair. You cannot specify 2 cutoffs for style <em>lj/cut/soft</em>,
			since it has no Coulombic terms. For the <em>coul/cut/soft</em> and
			<em>coul/long/soft</em> only lambda and the optional cutoff2 are to be
			specified.</p>
			<p>Style <em>lj/cut/tip4p/long/soft</em> implements a soft-core version of the
			TIP4P water model. The usage of this pair style is documented in the
			<a class="reference internal" href="pair_lj.html"><span class="doc">pair_lj</span></a> styles. The soft-core version introduces the
			lambda parameter to the list of arguments, after epsilon and sigma in
			the <a class="reference internal" href="pair_coeff.html"><span class="doc">pair_coeff</span></a> command. The paratemers n, alpha_LJ
			and alpha_C are set in the <a class="reference internal" href="pair_style.html"><span class="doc">pair_style</span></a> command,
			before the cutoffs.</p>
			<p>Style <em>lj/charmm/coul/long/soft</em> implements a soft-core version of the
			CHARMM version of LJ interactions with an additional switching
			function S(r) that ramps the energy and force smoothly to zero between
			an inner and outer cutoff. The usage of this pair style is documented
			in the <a class="reference internal" href="pair_charmm.html"><span class="doc">pair_charmm</span></a> styles. The soft-core version
			introduces the lambda parameter to the list of arguments, after
			epsilon and sigma in the <a class="reference internal" href="pair_coeff.html"><span class="doc">pair_coeff</span></a> command (and
			before the optional eps14 and sigma14). The paratemers n,
			alpha_LJ and alpha_C are set in the <a class="reference internal" href="pair_style.html"><span class="doc">pair_style</span></a>
			command, before the cutoffs.</p>
			<p>The <em>coul/cut/soft</em>, <em>coul/long/soft</em> and <em>tip4p/long/soft</em> substyles
			are designed to be combined with other pair potentials via the
			<a class="reference internal" href="pair_hybrid.html"><span class="doc">pair_style hybrid/overlay</span></a> command. This is because
			they have no repulsive core. Hence, if used by themselves, there will
			be no repulsion to keep two oppositely charged particles from
			overlapping each other. In this case, if lambda = 1, a singularity may
			occur. These substyles are suitable to represent charges embedded in
			the Lennard-Jones radius of another site (for example hydrogen atoms
			in several water models).</p>
			<p>NOTES: When using the core-softed Coulomb potentials with long-range
			solvers (<em>coul/long/soft</em>, <em>lj/cut/coul/long/soft</em>, etc.) in a free
			energy calculation in which sites holding electrostatic charges are
			being created or anihilated (using <a class="reference internal" href="fix_adapt_fep.html"><span class="doc">fix adapt/fep</span></a>
			and <a class="reference internal" href="compute_fep.html"><span class="doc">compute fep</span></a>) it is important to adapt both the
			lambda activation parameter (from 0 to 1, or the reverse) and the
			value of the charge (from 0 to its final value, or the reverse). This
			ensures that long-range electrostatic terms (kspace) are correct. It
			is not necessary to use core-softed Coulomb potentials if the van der
			Waals site is present during the free-energy route, thus avoiding
			overlap of the charges. Examples are provided in the LAMMPS source
			directory tree, under examples/USER/fep.</p>
			<hr class="docutils" />
			<p>Styles with a <em>gpu</em>, <em>intel</em>, <em>kk</em>, <em>omp</em>, or <em>opt</em> suffix are
			functionally the same as the corresponding style without the suffix.
			They have been optimized to run faster, depending on your available
			hardware, as discussed in <a class="reference internal" href="Section_accelerate.html"><span class="doc">Section 5</span></a>
			of the manual. The accelerated styles take the same arguments and
			should produce the same results, except for round-off and precision
			issues.</p>
			<p>These accelerated styles are part of the GPU, USER-INTEL, KOKKOS,
			USER-OMP and OPT packages, respectively. They are only enabled if
			LAMMPS was built with those packages. See the <a class="reference internal" href="Section_start.html#start-3"><span class="std std-ref">Making LAMMPS</span></a> section for more info.</p>
			<p>You can specify the accelerated styles explicitly in your input script
			by including their suffix, or you can use the <a class="reference internal" href="Section_start.html#start-7"><span class="std std-ref">-suffix command-line switch</span></a> when you invoke LAMMPS, or you can
			use the <a class="reference internal" href="suffix.html"><span class="doc">suffix</span></a> command in your input script.</p>
			<p>See <a class="reference internal" href="Section_accelerate.html"><span class="doc">Section 5</span></a> of the manual for
			more instructions on how to use the accelerated styles effectively.</p>
			<hr class="docutils" />
			<p><strong>Mixing, shift, tail correction, restart info</strong>:</p>
			<p>For atom type pairs I,J and I != J, the epsilon and sigma coefficients
			and cutoff distance for this pair style can be mixed.
			The default mix value is <em>geometric</em>. See the “pair_modify” command
			for details.</p>
			<p>These pair styles support the <a class="reference internal" href="pair_modify.html"><span class="doc">pair_modify</span></a> shift
			option for the energy of the Lennard-Jones portion of the pair
			interaction.</p>
			<p>These pair styles support the <a class="reference internal" href="pair_modify.html"><span class="doc">pair_modify</span></a> tail
			option for adding a long-range tail correction to the energy and
			pressure for the Lennard-Jones portion of the pair interaction.</p>
			<p>These pair styles write information to <a class="reference internal" href="restart.html"><span class="doc">binary restart files</span></a>, so pair_style and pair_coeff commands do not need
			to be specified in an input script that reads a restart file.</p>
			</div>
			<hr class="docutils" />
			<div class="section" id="restrictions">
			<h2>Restrictions</h2>
			<p>To avoid division by zero do not set sigma = 0; use the lambda
			parameter instead to activate/deactivate interactions, or use
			epsilon = 0 and sigma = 1. Alternatively, when sites do not
			interact though the Lennard-Jones term the <em>coul/long/soft</em> or
			similar substyle can be used via the
			<a class="reference internal" href="pair_hybrid.html"><span class="doc">pair_style hybrid/overlay</span></a> command.</p>
			<hr class="docutils" />
			<p>All of the plain <em>soft</em> pair styles are part of the USER-FEP package.
			The <em>long</em> styles also requires the KSPACE package to be installed.
			They are only enabled if LAMMPS was built with those packages. See
			the <a class="reference internal" href="Section_start.html#start-3"><span class="std std-ref">Making LAMMPS</span></a> section for more info.</p>
