Stability of complex Langevin dynamics in effective models
Gert Aarts, Frank A. James, Jan M. Pawlowski +3
The sign problem at nonzero chemical potential prohibits the use of importance sampling in lattice simulations. Since complex Langevin dynamics does not rely on importance sampling…
Gauge cooling in complex Langevin for QCD with heavy quarks
Erhard Seiler, Dénes Sexty, Ion-Olimpiu Stamatescu
We employ a new method, "gauge cooling", to stabilize complex Langevin simulations of QCD with heavy quarks. The results are checked against results obtained with reweigthing; we f…
Emergent gravity in two dimensions
D. Sexty, C. Wetterich
We explore models with emergent gravity and metric by means of numerical simulations. A particular type of two-dimensional non-linear sigma-model is regularized and discretized on…
Over-populated gauge fields on the lattice
J. Berges, S. Schlichting, D. Sexty
We study nonequilibrium dynamics of SU(2) pure gauge theory starting from initial over-population, where intense classical gauge fields are characterized by a single momentum scale…
Nonthermal fixed points and solitons in a one-dimensional Bose gas
Maximilian Schmidt, Sebastian Erne, Boris Nowak +2
Single-particle momentum spectra for a dynamically evolving one-dimensional Bose gas are analysed in the semi-classical wave limit. Representing one of the simplest correlation fun…
Bose condensation far from equilibrium
J. Berges, D. Sexty
The formation of Bose condensates far from equilibrium can play an important role in our understanding of collision experiments of heavy nuclei or for the evolution of the early un…
