Solving the Bethe-Salpeter equation with exponential convergence
Markus Wallerberger, Hiroshi Shinaoka, Anna Kauch
The Bethe-Salpeter equation plays a crucial role in understanding the physics of correlated fermions, relating to optical excitations in solids as well as resonances in high-energy…
Statistical error estimates in dynamical mean-field theory and extensions thereof
Patrick Kappl, Markus Wallerberger, Josef Kaufmann +2
We employ the jackknife algorithm to analyze the propagation of the statistical quantum Monte Carlo error through the Bethe--Salpeter equation. This allows us to estimate the error…
Diagrammatic Monte Carlo Method for Impurity Models with General Interactions and Hybridizations
Jia Li, Markus Wallerberger, Emanuel Gull
We present a diagrammatic Monte Carlo method for quantum impurity problems with general interactions and general hybridization functions. Our method uses a recursive determinant sc…
