Imaginary Time Correlations and the phaseless Auxiliary Field Quantum Monte Carlo (1311.1071v1)
Published 5 Nov 2013 in cond-mat.str-el
Abstract: The phaseless Auxiliary Field Quantum Monte Carlo method provides a well established approximation scheme for accurate calculations of ground state energies of many-fermions systems. Here we apply the method to the calculation of imaginary time correlation functions. We give a detailed description of the technique and we test the quality of the results for static and dynamic properties against exact values for small systems.
