WebJan 20, 2024 · The Ehrenfest dynamics, representing a quantum-classical mean-field type coupling, is a widely used approximation in quantum molecular dynamics. In this paper, we propose a time-splitting method for an Ehrenfest dynamics, in the form of a nonlinearly coupled Schrödinger-Liouville system. We prove that our splitting scheme is stable … WebThis flaw in Ehrenfest dynamics, a result of the mean-field approximation, means that our semi-classical system will never achieve thermal equilibrium between the ions and the electrons. The failure to equilibrate is due to the fact that Ehrenfest dynamics does not reproduce the effect of spontaneous phonon emission. haverstraw lwrp
