Physical and unphysical regimes of self-consistent many-body perturbation theory
K. Van Houcke, E. Kozik, R. Rossi +2
In the standard framework of self-consistent many-body perturbation theory, the skeleton series for the self-energy is truncated at a finite order and plugged into th…

Resummation of diagrammatic series with zero convergence radius for strongly correlated fermions
Riccardo Rossi, Takahiro Ohgoe, Kris Van Houcke +1
We demonstrate that summing up series of Feynman diagrams can yield unbiased accurate results for strongly-correlated fermions even when the convergence radius vanishes. We conside…
