摘要
Using the path integral representation,the Hubbard and the periodic Anderson model on D-dimensional cubic lattice are transformed into field theories of fermions in D+1 dimensions.These theories at half-filling possess a positive definite real symmetry fermion matrix and can be simulated using the hybrid Monte Carlo method.
