Simulating Yang-Mills theories with a complex coupling
Jan M. Pawlowski, Manuel Scherzer, Christian Schmidt +2
We propose a novel simulation strategy for Yang-Mills theories with a complex coupling, based on the Lefschetz thimble decomposition. We envisage, that the approach developed in th…
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…
Simulating gauge theories on Lefschetz thimbles
Jan M. Pawlowski, Manuel Scherzer, Christian Schmidt +2
Lefschetz thimbles have been proposed recently as a possible solution to the complex action problem (sign problem) in Monte Carlo simulations. Here we discuss pure abelian gauge th…
Controlling Complex Langevin simulations of lattice models by boundary term analysis
M. Scherzer, E. Seiler, D. Sexty +1
One reason for the well known fact that the Complex Langevin (CL) method sometimes fails to converge or converges to the wrong limit has been identified long ago: it is insufficien…
Spectral Reconstruction with Deep Neural Networks
Lukas Kades, Jan M. Pawlowski, Alexander Rothkopf +5
We explore artificial neural networks as a tool for the reconstruction of spectral functions from imaginary time Green's functions, a classic ill-conditioned inverse problem. Our a…
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…
Reweighting Lefschetz Thimbles
Stefan Bluecher, Jan M. Pawlowski, Manuel Scherzer +4
One of the main challenges in simulations on Lefschetz thimbles is the computation of the relative weights of contributing thimbles. In this paper we propose a solution to that pro…
Getting even with CLE
Gert Aarts, Kirill Boguslavski, Manuel Scherzer +3
In the landscape of approaches toward the simulation of Lattice Models with complex action the Complex Langevin (CL) appears as a straightforward method with a simple, well defined…
Machine Learning of Explicit Order Parameters: From the Ising Model to SU(2) Lattice Gauge Theory
Sebastian Johann Wetzel, Manuel Scherzer
We present a procedure for reconstructing the decision function of an artificial neural network as a simple function of the input, provided the decision function is sufficiently sy…
