Fermionic sign problem minimization by constant path integral contour shifts

Physical review B, 2023
The path integral formulation of quantum mechanical problems including fermions is often affected by a severe numerical sign problem. We show how such a sign problem can be alleviated by a judiciously chosen constant imaginary offset to the path integral.
