Effective Hamiltonian Dynamics via the Maupertuis Principle
Hartmut Schwetlick, Daniel C. Sutton, Johannes Zimmer
We consider the dynamics of a Hamiltonian particle forced by a rapidly oscillating potential in -dimensional space. As alternative to the established approach of averaging Ha…
Symmetries and Geometrical Properties of Dynamical Fluctuations in Molecular Dynamics
Robert L. Jack, Marcus Kaiser, Johannes Zimmer
We describe some general results that constrain the dynamical fluctuations that can occur in non-equilibrium steady states, with a focus on molecular dynamics. That is, we consider…
Computing diffusivities from particle models out of equilibrium
Peter Embacher, Nicolas Dirr, Johannes Zimmer +1
A new method is proposed to numerically extract the diffusivity of a (typically nonlinear) diffusion equation from underlying stochastic particle systems. The proposed strategy req…
Canonical structure and orthogonality of forces and currents in irreversible Markov chains
Marcus Kaiser, Robert L. Jack, Johannes Zimmer
We discuss a canonical structure that provides a unifying description of dynamical large deviations for irreversible finite state Markov chains (continuous time), Onsager theory, a…
