Complex Langevin simulations with a kernel
Michael Mandl, Erhard Seiler, Dénes Sexty
We discuss recent developments regarding the use of kernels in complex Langevin simulations. In particular, we outline how a kernel can be used to solve the problem of wrong conver…

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…
