摘要：
Using a new method of storing and updating one particle Green's functions the computer time for the simulation of correlated fermi systems in the grand canonical ensemble scales linearly with the inverse temperature. This reduces the number of operations by a factor of typically 20 and more at low temperatures compared with the standard algorithm.
