Nature of problem:We present here a program for performing Monte Carlo (MC) simulations in discrete fermionic systems. We use a special version of the so-called determinantal method. The algorithm is based in the standard Metropolis method, but makes use of a non-uniform probability distribution for the selection of the transition-candidate states. Detailed balance is perserved by suitably modifying the Metropolis acceptance-rejection test. The method was originally developed and used in a one dimensional spinless fermion model. We apply it to the case of a two dimensional multi-band Hubbard model. The program code is self-contained and optimized for use in vectorial computers. | ||

Running time:84 min 34 sec for the test run. | ||
