Description
We investigate contour deformation strategies for alleviating the finite-density sign problem in the heavy-dense limit of QCD in two, three, and four dimensions. To reduce the number of integration variables, we work in Polyakov gauge and consider complex deformations of the Polyakov loop eigenvalues. We study approaches based on holomorphic flow equations as well as numerical optimization, using the average phase as the primary diagnostic for the severity of the sign problem. We find that both approaches can considerably alleviate the sign problem in heavy-dense QCD.
