Discovering a well-conditioned analytic continuation problem via dictionary learning

Thomas Chuna, Phil-Alexander Hofmann, Alexander Benedix-Robles +1

Many fields of physics use quantum Monte Carlo (QMC) simulations to simulate quantum systems in imaginary-time $τ$ and estimate imaginary-time correlation functions (ITCF). However…

PyLIT: Reformulation and implementation of the analytic continuation problem using kernel representation methods

Alexander Benedix Robles, Phil-Alexander Hofmann, Thomas Chuna +2

Path integral Monte Carlo (PIMC) simulations are a cornerstone for studying quantum many-body systems. The analytic continuation (AC) needed to estimate dynamic quantities from the…
