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…
Deconfinement transition line with the Complex Langevin equation up to
M. Scherzer, D. Sexty, I. -O. Stamatescu
We study the deconfinement transition line in QCD for quark chemical potentials up to (). To circumvent the sign problem we use the complex Langevin e…
Reweighting Lefschetz Thimbles
Stefan Bluecher, Jan M. Pawlowski, Manuel Scherzer +4
We present a novel reweighting technique to calculate the relative weights in the Lefschetz thimble decomposition of a path integral. Our method is put to work using a one-l…
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…
Complex Langevin and boundary terms
Manuel Scherzer, Erhard Seiler, Dénes Sexty +1
As is well known the Complex Langevin (CL) method sometimes fails to converge or converges to the wrong limit. We identified one reason for this long ago: insufficient decay of the…
