Lattice field theories with a sign problem
Gert Aarts, Dénes Sexty
The sign problem obstructs the determination of the QCD phase diagram in the temperature-baryon chemical potential plane using lattice QCD. We review the sign problem in QCD and re…
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…
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…
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…
