Abstract

A new hybrid-type algorithm is proposed for simulations of fermion lattices. The direct calculation of the matrix inversion operation is replaced with a stochastic iteration procedure. The computation time grows linearly with the increase of spatial system size. Applications to the Hubbard model on the 62, 122 and 162 square lattices are illustrated with no indication of enhancement for superconducting correlation in the non-half-filled band.
