The Role of Integration Cycles in Complex Langevin Simulations
Michael W. Hansen, Michael Mandl, Erhard Seiler +1
Complex Langevin simulations are an attempt to solve the sign (or complex-action) problem encountered in various physical systems of interest. The method is based on a complexifica…

Kernels and integration cycles in complex Langevin simulations
Michael Mandl, Michael W. Hansen, Erhard Seiler +1
The method of complex Langevin simulations is a tool that can be used to tackle the complex-action problem encountered, for instance, in finite-density lattice quantum chromodynami…

Testing dynamical stabilization of Complex Langevin simulations of QCD
Michael W. Hansen, Dénes Sexty
We study complex Langevin simulations of a toy model as well as QCD, supplemented with a dynamical stabilization (DS) term, which was proposed to regularize the complexified proces…
