Recent advances in Diagrammatic Monte Carlo

ORAL

Abstract

In this talk, I will present some of the recent advances obtained in the automatic high-order computations of Feynman diagrams for fermionic systems. I will discuss in particular the Connected Determinant Monte Carlo algorithm (CDet) [1, 2] and its extensions, and I will present results for the Fermi-Hubbard model as the paradigmatic strongly-correlated fermionic system.
