Description

Fermionic field theories at finite density suffer from a sign problem, making lattice calculations exponentially expensive in the volume. This sign problem can be reduced or eliminated by complexifying configuration space, and integrating over a contour deformed from the real plane. We present an algorithm for determining integration contours with reduced sign problems. We give results from this algorithm for both 1+1 and 2+1 dimensional field theories at finite density.
