<strong>Molecular</strong> <strong>Dynamics</strong> <strong>Chapter</strong> 1.1<br />

Stochastic Collision method:<br />

Anderson Thermostat<br />

Frequency <strong>in</strong>fluence on the phase space exploration:<br />

If frequency is too high, collision will dom<strong>in</strong>ate and <strong>in</strong>hibit an efficient<br />

exploration of the phase space to meet the ergodic requirement.<br />

If frequency is too low, the canonical distribution will be formed slowly<br />

to meet the canonical requirement.<br />

Suggested collision rate:<br />

ρ<br />
