Anisotropic scattering rates in strain-tuned SrRuO
Ben Currie, David T. S. Perkins, Evgeny Kozik +2
Motivated by recent angle-resolved photoemission spectroscopy (ARPES) experiments, we analyze the temperature, frequency, and momentum dependence of the single-particle scattering…

Numerical validation of an ultracold Hubbard quantum simulator
Ben Currie, John Sturt, Evgeny Kozik
We apply the formally exact Diagrammatic Monte Carlo (DiagMC) method to probe the unprecedentedly low-temperature regime recently achieved in an ultracold-atom quantum simulation o…

Exploiting Parallelism for Fast Feynman Diagrammatics
John Sturt, Evgeny Kozik
Diagrammatic expansions are a paradigmatic and powerful tool of quantum many-body theory. Their evaluation to high order, e.g., by the Diagrammatic Monte Carlo technique, can provi…
