Complex Langevin: Correctness criteria, boundary terms and spectrum
Erhard Seiler, Dénes Sexty, Ion-Olimpiu Stamatescu
The Complex Langevin (CL) method to simulate `complex probabilities', ideally produces expectation values for the observables that converge to a limit equal to the expectation valu…
Complex Langevin boundary terms in lattice models
Michael W. Hansen, Erhard Seiler, Dénes Sexty +1
In complex Langevin simulations, the insufficient decay of the probability density near infinity leads to boundary terms that spoil the formal argument for correctness. We present…
Complex Langevin: Boundary terms at poles of the drift
Erhard Seiler
The complex Langevin method is a general method to treat systems with complex action, such as QCD at nonzero density. The formal justification relies on the absence of certain boun…
Complex Langevin: Boundary terms at poles
Erhard Seiler
We discuss the problem of possible boundary terms at poles of the drift in the complex Langevin method, which spoil correctness of the method. For the simplest, however paradigmati…
Complex Langevin: Boundary terms and application to QCD
Manuel Scherzer, Erhard Seiler, Dénes Sexty +1
We employ the Complex Langevin method for simulation of complex-valued actions. First, we show how to test for convergence of the method by explicitely computing boundary terms and…
Schwinger-Dyson equations and line integrals
Lorenzo Luis Salcedo, Erhard Seiler
The Complex Langevin (CL) method sometimes shows convergence to the wrong limit, even though the Schwinger-Dyson Equations (SDE) are fulfilled. We analyze this problem in a more ge…
