Simulating Yang-Mills theories with a complex coupling

no code implementations11 Jan 2021 Jan M. Pawlowski, Manuel Scherzer, Christian Schmidt, Felix P. G. Ziegler, Felix Ziesché

We discuss the structure of Generalized Lefschetz thimbles for pure Yang-Mills theories with a complex gauge coupling $\beta$ and show how to incorporate the gauge orbits.

Spectral Reconstruction with Deep Neural Networks

no code implementations10 May 2019 Lukas Kades, Jan M. Pawlowski, Alexander Rothkopf, Manuel Scherzer, Julian M. Urban, Sebastian J. Wetzel, Nicolas Wink, Felix P. G. Ziegler

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.
