Lattice Field Theory with the Sign Problem and the Maximum Entropy Method
Masahiro Imachi, Yasuhiko Shinno, Hiroshi Yoneyama
Abstract
Although numerical simulation in lattice field theory is one of the most effective tools to study non-perturbative properties of field theories, it faces serious obstacles coming from the sign problem in some theories such as finite density QCD and lattice field theory with the θ term. We reconsider this problem from the point of view of the maximum entropy method.
