Finite-density equation of state of hot QCD using the complex Langevin equation
Michael Mandl, Dénes Sexty, Daniel Unterhuber
We present the results of continuum-extrapolated lattice simulations of quantum chromodynamics (QCD) above the crossover temperature and for unprecedentedly high baryon densities a…
Correctness criteria for complex Langevin
Michael Mandl
The complex Langevin approach is a promising method for the numerical treatment of systems with a sign problem, for which conventional lattice field theory techniques based on impo…
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…
