To provide a theoretical basis for this interpretation, one may invoke the system-bath ansatz á la Zwanzig. Goal: Use normal modes partitioning of Langevin dynamics for kinetics and sampling for implicitly solvated proteins. Approach: Use normal modes to partition system by frequency: low frequency modes are propagated using Langevin dynamics; high frequency modes are overdamped using Brownian dynamics In this paper we show the possibility of using very mild stochastic damping to stabilize long time step integrators for Newtonian molecular dynamics.

2 A program for Molecular dynamics and Langevin dynamics We are here going to simulate an interacting particles in two dimensions. An important reason for looking at this problem in two dimensions is that it then becomes much easier to visualize the configurations (which is one of the voluntary exercises). LANGEVIN MOLECULAR DYNAMICS DERIVED FROM EHRENFEST DYNAMICS ANDERS SZEPESSY Abstract. Stochastic Langevin molecular dynamics for nuclei is derived from the Ehrenfest Hamiltonian system (also called quantum classical molecular dynamics) in a Kac-Zwanzig setting, with the initial data for the electrons stochastically perturbed from the ground state However, the time scale of the Langevin dynamics and molecular dynamics are different and an ansatz for the persistence probability relaxation time was needed.
