Sign Problem and Mem * †

The sign problem is notorious in Monte Carlo simulations of lattice QCD with the finite density, lattice field theory (LFT) with a θ term and quantum spin models. In this report, to deal with the sign problem, we apply the maximum entropy method (MEM) to LFT with the θ term and investigate to what extent the MEM is applicable to this issue. Based on this study, we also make a brief comment abou...
