Webnamics (MD) simulation, the Trotter factorization of the Liouville propagator was used to derive a reversible mul tiple time scale MD method. This was the major focus of the paper. The Trotter factorization was also used to derive a third-order MD-predictor algorithm which the authors named "position Verlet." The algorithm, with the author's WebThe method is based on a Trotter-factorization of the classical Liouville-operator for the time evolution of the classical system, resulting in a time reversible propagation … WebThis symmetrical Trotter factorization can be repeated as many times as desired, and at least one more factorization of the inner propagator is typically required to separate the po- sition and velocity components of the propagator.
