Multi-flavor massless QED$_2$ at finite densities via Lefschetz thimbles
Published 20 Dec 2016 in hep-th and hep-lat | (1612.06529v3)
Abstract: We consider multi-flavor massless $(1+1)$-dimensional QED with chemical potentials at finite spatial length and the zero-temperature limit. Its sign problem is solved using the mean-field calculation with complex saddle points.
