Dynamical gauge invariance of statistical mechanics
Johanna Müller, Florian Sammüller, Matthias Schmidt
We investigate gauge invariance against phase space shifting in nonequilibrium systems, as represented by time-dependent many-body Hamiltonians that drive an initial ensemble out o…
Gauge Invariance of Equilibrium Statistical Mechanics
Johanna Müller, Sophie Hermann, Florian Sammüller +1
We identify a recently proposed shifting operation on classical phase space as a gauge transformation for statistical mechanical microstates. The infinitesimal generators of the co…
Local measures of fluctuations in inhomogeneous liquids: Statistical mechanics and illustrative applications
Tobias Eckert, Nex C. X. Stuhlmüller, Florian Sammüller +1
We show in detail how three one-body fluctuation profiles, namely the local compressibility, the local thermal susceptibility, and the reduced density, can be obtained from a stati…
Adaptive Brownian Dynamics
Florian Sammüller, Matthias Schmidt
A framework for performant Brownian Dynamics (BD) many-body simulations with adaptive timestepping is presented. Contrary to the Euler-Maruyama scheme in common non-adaptive BD, we…
