Recent developments at finite density on the lattice
Published 6 Feb 2015 in hep-lat, hep-th, and nucl-th | (1502.01850v2)
Abstract: Some recent developments to handle the numerical sign problem in QCD and related theories at nonzero density are reviewed. In this contribution I focus on changing the integration order to soften the severity of the sign problem, the density of states, and the extension into the complex plane (complex Langevin dynamics and Lefshetz thimbles).
