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…
