| Research Abstract |
We have developed a novel approach to calculate time correlation functions for quantum liquids with the ultimate goal of obtaining numerically exact solutions. This method is based on the cluster expansion technique and the complex-time propagator of the whole system is constructed by those of a few particles systems, which are evaluated quite accurately. We have applied this method to time correlation functions of liquid para-hydrogen and liquid helium and succeeded in obtaining converged results for relatively short-time regions. The extension to identical particle systems(Bose and Fermi particles) is also carried and the effects of particle exchanges on the time correlation functions are examined in detail.
