A modified Lowe-Andersen thermostat for a hard sphere fluid

摘要

.In order to model the thermal interaction between two hard sphere particles, we propose a small modification of the Lowe-Andersen thermostat, a well-known numerical thermostat that acts on selected pairs of particles. The simulation procedure presented here is local, easy to implement and computationally inexpensive while perturbing the natural dynamics of the system in a minimal fashion.
