Continuous Estimators for CT-HYB — •Pavel Augustinský — University of Augsburg

We present an improved algorithm for measurement of the Green's function in the hybridization-expansion quantum Monte Carlo. The method is based on using continuous rather then discrete delta-function estimators. It fixes drawbacks of the standard approach at low perturbation orders and it can produce high-accuracy data for numerical analytical continuation of the selfenergy.
