Abstract
We improve the classical molecular dynamics (MD) method by a J-walking micr ocanonical Monte Carlo (MC) scheme to overcome broken ergodicity. This MC m ethod rigorously samples the MD ensemble at finite energy and angular momen tum. It is illustrated on the nonlinear dynamics of a 13-atom Lennard-Jones cluster.
