Imaginary time correlations and the phaseless auxiliary field quantum Monte Carlo / M. Motta, D.E. Galli, S. Moroni, E. Vitali. - In: THE JOURNAL OF CHEMICAL PHYSICS. - ISSN 0021-9606. - 140:2(2014 Jan 13), pp. 024107.1-024107.12. [10.1063/1.4861227]
Abstract:
The phaseless Auxiliary Field Quantum Monte Carlo (AFQMC) method provides a well established approximation scheme for accurate calculations of ground state energies of many-fermions systems. Here we address the possibility of calculating imaginary time correlation functions with the phaseless AFQMC. We give a detailed description of the technique and test the quality of the results for static properties and imaginary time correlation functions against exact values for small systems.
