Advantages of the Rayleigh-Lowe-Andersen thermostat in soft sphere molecular dynamics simulations.

The Rayleigh-Lowe-Andersen thermostat is a momentum-conserving, Galilean-invariant analogue of the Andersen thermostat, like the original (Maxwellian) Lowe-Andersen thermostat. However, the Rayleigh-Lowe-Andersen thermostat remains local even if the fluid density becomes low. By using a minimized thermostat interaction radius we show with a molecular dynamics simulation that the Rayleigh-Lowe-Andersen thermostat affects the natural dynamics of a low-density Lennard-Jones fluid in a minimal fashion.
