  11. Tracking the Footprints of Spin Fluctuations: A Multi-Method, Multi-Messenger Study of the Two-Dimensional Hubbard Model

    Publication
    The Hubbard model represents the fundamental model for interacting quantum systems and electronic correlations. Using the two-dimensional half-filled Hubbard model at weak coupling as testing grounds …

    We describe a formulation of the density matrix embedding theory at finite temperature. We present a generalization of the ground-state bath orbital construction that embeds a mean …

  14. Not all doped Mott insulators have a pseudogap: key role of van Hove singularities

    Publication
    The Mott insulating phase of the parent compounds is frequently taken as starting point for the underdoped high-Tc cuprate superconductors. In particular, the pseudogap state is often …

  15. Pseudogap and electronic structure of electron-doped Sr2IrO4

    Publication
    We present a theoretical investigation of the effects of correlations on the electronic structure of the Mott insulator Sr2IrO4 upon electron doping. A rapid collapse of the Mott …

  16. Spin-Orbit Coupling and Electronic Correlations in Sr2RuO4

    Publication
    We investigate the interplay of spin-orbit coupling (SOC) and electronic correlations in Sr2RuO4 using dynamical mean-field theory. We find that SOC does not affect the correlation …

  17. Pseudogap and Fermi surface topology in the two-dimensional Hubbard model

    Publication
    One of the distinctive features of hole-doped cuprate superconductors is the onset of a `pseudogap' below a temperature T∗. Recent experiments suggest that there may be a …

  18. Topological order in the pseudogap metal

    Publication
    We compute the electronic Green's function of the topologically ordered Higgs phase of a SU(2) gauge theory of fluctuating antiferromagnetism on the square lattice. The results …
