摘要: We present a new variant of Monte Carlo procedure for euclidean quantum field theories with fermions. On lattice every term contributing to the expansion fermion determinant is interpreted as configuration self-avoiding oriented closed loops which represent fermionic vacuum fluctuations. These are related Symanzik’s polymer description theory. The method extended determination Green’s functions. test our on Scalapino-Sugar model in one, two, three, and four dimensions. Good agreement exactly known results found.
