	<h2>Description</h2>
	<p>The <em>lj/mdf</em>, <em>buck/mdf</em> and <em>lennard/mdf</em> compute the standard 12-6
	Lennard-Jones and Buckingham potential with the addition of a taper
	function that ramps the energy and force smoothly to zero between an
	inner and outer cutoff.</p>
	<img alt="_images/pair_mdf-1.jpg" class="align-center" src="_images/pair_mdf-1.jpg" />
	<p>The tapering, <em>f(r)</em>, is done by using the Mei, Davenport, Fernando
	function <a class="reference internal" href="#mei"><span class="std std-ref">(Mei)</span></a>.</p>
	<img alt="_images/pair_mdf-2.jpg" class="align-center" src="_images/pair_mdf-2.jpg" />
	<p>where</p>
	<img alt="_images/pair_mdf-3.jpg" class="align-center" src="_images/pair_mdf-3.jpg" />
	<p>Here <em>r_m</em> is the inner cutoff radius and <em>r_cut</em> is the outer cutoff
	radius.</p>
	<hr class="docutils" />
	<p>For the <em>lj/mdf</em> pair_style, the potential energy, <em>E(r)</em>, is the
	standard 12-6 Lennard-Jones written in the epsilon/sigma form:</p>
	<img alt="_images/pair_mdf-4.jpg" class="align-center" src="_images/pair_mdf-4.jpg" />
	<p>The following coefficients must be defined for each pair of atoms
	types via the pair_coeff 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 commands</span></a>, or by mixing as described
	below:</p>
	<ul class="simple">
	<li>epsilon (energy units)</li>
	<li>sigma (distance units)</li>
	<li>r_m (distance units)</li>
	<li>r_<em>cut</em> (distance units)</li>
	</ul>
	<hr class="docutils" />
	<p>For the <em>buck/mdf</em> pair_style, the potential energy, <em>E(r)</em>, is the
	standard Buckingham potential:</p>
	<img alt="_images/pair_mdf-5.jpg" class="align-center" src="_images/pair_mdf-5.jpg" />
	<ul class="simple">
	<li>A (energy units)</li>

	<li>C (energy-distance^6 units)</li>
	<li>r_m (distance units)</li>
	<li>r_<em>cut</em>$ (distance units)</li>
	</ul>
	<hr class="docutils" />
	<p>For the <em>lennard/mdf</em> pair_style, the potential energy, <em>E(r)</em>, is the
	standard 12-6 Lennard-Jones written in the $A/B$ form:</p>
	<img alt="_images/pair_mdf-6.jpg" class="align-center" src="_images/pair_mdf-6.jpg" />
	<p>The following coefficients must be defined for each pair of atoms
	types via the pair_coeff command as in the examples above, or in the
	data file or restart files read by the read_data or read_restart
	commands, or by mixing as described below:</p>
	<ul class="simple">
	<li>A (energy-distance^12 units)</li>
	<li>B (energy-distance^6 units)</li>
	<li>r_m (distance units)</li>
	<li>r_<em>cut</em> (distance units)</li>
	</ul>
	<hr class="docutils" />
	<p><strong>Mixing, shift, table, tail correction, restart, rRESPA info</strong>:</p>
	<p>For atom type pairs I,J and I != J, the epsilon and sigma coefficients
	and cutoff distance for all of the lj/cut pair styles can be mixed.
	The default mix value is <em>geometric</em>. See the “pair_modify” command
	for details.</p>
	<p>All of the <em>lj/cut</em> 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>The <em>lj/cut/coul/long</em> and <em>lj/cut/tip4p/long</em> pair styles support the
	<a class="reference internal" href="pair_modify.html"><span class="doc">pair_modify</span></a> table option since they can tabulate
	the short-range portion of the long-range Coulombic interaction.</p>
	<p>All of the <em>lj/cut</em> 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>All of the <em>lj/cut</em> pair styles write their 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>
	<p>The <em>lj/cut</em> and <em>lj/cut/coul/long</em> pair styles support the use of the
	<em>inner</em>, <em>middle</em>, and <em>outer</em> keywords of the <a class="reference internal" href="run_style.html"><span class="doc">run_style respa</span></a> command, meaning the pairwise forces can be
	partitioned by distance at different levels of the rRESPA hierarchy.
	The other styles only support the <em>pair</em> keyword of run_style respa.
	See the <a class="reference internal" href="run_style.html"><span class="doc">run_style</span></a> command for details.</p>
