Diagrammatic Monte Carlo for real materials
ORAL
Abstract
We present a systematic method for reaching beyond the GW approximation by Diagrammatic Monte Carlo (DiagMC) for first-principle simulations of real materials. DiagMC is used to provide an efficient estimation of higher-order self-energy and polarisability diagrams to achieve a controlled solution for ab initio Hamiltonians.
