Ab initio dynamical vertex approximation
Anna Galler, Patrik Thunström, Patrik Gunacker +2
Diagrammatic extensions of dynamical mean field theory (DMFT) such as the dynamical vertex approximation (DA) allow us to include non-local correlations beyond DMFT on all lengt…

Worm Improved Estimators in Continuous-time Quantum Monte Carlo
Patrik Gunacker, Markus Wallerberger, Tin Ribic +3
We derive the improved estimators for general interactions and employ these for the continuous-time quantum Monte Carlo method. Using a worm algorithm we show how measuring higher-…
