Підтримка:This paper is a contribution to the Proceedings of the O’Raifeartaigh Symposium on Non-Perturbative and Symmetry Methods in Field Theory (June 22–24, 2006, Budapest, Hungary). One of the authors (H.Y.) is grateful to the organizers of the O’Raifeartaigh Symposium on Non-Perturbative and Symmetry Methods in Field Theory for providing him an opportunity to present a talk. He also thanks them for their warm hospitality. The symposium reminded him well that he had enjoyed intensive discussions with Lochlainn and other colleagues (A. Wipf, especially) at DIAS.
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.
