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…
Complex Langevin dynamics in the SU(3) spin model at nonzero chemical potential revisited
Gert Aarts, Frank A. James
The three-dimensional SU(3) spin model is an effective Polyakov loop model for QCD at nonzero temperature and density. It suffers from a sign problem at nonzero chemical potential.…
Complex Langevin dynamics: criteria for correctness
Gert Aarts, Frank A. James, Erhard Seiler +1
The complex Langevin method is a leading candidate for solving the sign problem occurring in various physical situations, notably QCD at finite chemical potential. Its most vexing…
Complex Langevin: Etiology and Diagnostics of its Main Problem
Gert Aarts, Frank A. James, Erhard Seiler +1
The complex Langevin method is a leading candidate for solving the so-called sign problem occurring in various physical situations. Its most vexing problem is that in some cases it…
The XY model at finite chemical potential using complex Langevin dynamics
Gert Aarts, Frank A. James
The three-dimensional XY model is studied at finite chemical potential using complex Langevin dynamics. An adaptive stepsize algorithm is implemented to cure the problem of runaway…
On the convergence of complex Langevin dynamics: the three-dimensional XY model at finite chemical potential
Gert Aarts, Frank A. James
The three-dimensional XY model is studied at finite chemical potential using complex Langevin dynamics. The validity of the approach is probed at small chemical potential using ima…
