A Hybrid Monte Carlo algorithm for sampling rare events in space-time histories of stochastic fields
G. Margazoglou, L. Biferale, R. Grauer +4
We introduce a variant of the Hybrid Monte Carlo (HMC) algorithm to address large-deviation statistics in stochastic hydrodynamics. Based on the path-integral approach to stochasti…
Dissipative Bose-Einstein condensation in contact with a thermal reservoir
Stephan Caspar, Florian Hebenstreit, David Mesterházy +1
We investigate the real-time dynamics of open quantum spin- or hardcore boson systems on a spatial lattice, which are governed by a Markovian quantum master equation. We deriv…
Multicritical behavior in models with two competing order parameters
Astrid Eichhorn, David Mesterházy, Michael M. Scherer
We employ the nonperturbative functional Renormalization Group to study models with an O(N_1)+O(N_2) symmetry. Here, different fixed points exist in three dimensions, corresponding…
Monte Carlo simulations of the randomly forced Burgers equation
P. Düben, D. Homeier, K. Jansen +3
The behaviour of the one--dimensional random--forced Burgers equation is investigated in the path integral formalism, using a discrete space--time lattice. We show that by means of…
