Coupling different levels of resolution in molecular dynamics. — •Simon Poblete, Matej Praprotnik, Kurt Kremer, and Luigi Delle Site — Max-Planck-Institut fuer Polymerforschung, Mainz, Germany.

Simulation schemes that allow to change molecular representation in a subvolume of the simulation box while preserving the equilibrium with the surrounding introduce conceptual problems of thermodynamic consistency. In this work we present a general scheme based on thermodynamic arguments which ensures thermodynamic equilibrium among the molecules of different representation. The robustness of the algorithm is tested for two examples, namely an adaptive resolution simulation, atomistic/coarse-grained, for a liquid of tetrahedral molecules and an adaptive resolution simulation of a binary mixture of tetrahedral molecules and spherical solutes.
