Description
In this talk I will describe our recent progress in the development of Diagrammatic Monte Carlo techniques for the two-dimensional Fermi-Hubbard model. I will describe how correlations can lead to qualitative changes in the Fermi surface, or to a selective destruction of quasiparticle excitations near the antinodes in the pseudogap regime.
