Conductivity in the square lattice Hubbard model at high temperatures: importance of vertex corrections
Jaksa Vucicevic, Jure Kokalj, Rok Zitko +3
Recent experiments on cold atoms in optical lattices allow for a quantitative comparison of the measurements to the conductivity calculations in the square lattice Hubbard model. H…

Biexciton Condensation in Electron-hole Doped Hubbard Bilayers -- A Sign-Problem-Free Quantum Monte Carlo Study
Xuxin Huang, Martin Claassen, Edwin W. Huang +2
The bilayer Hubbard model with electron-hole doping is an ideal platform to study excitonic orders due to suppressed recombination via spatial separation of electrons and holes. Ho…

Coupled charge and spin dynamics in a photo-excited Mott insulator
Nikolaj Bittner, Denis Golež, Hugo U. R. Strand +2
Using a nonequilibrium implementation of the extended dynamical mean field theory (EDMFT) we simulate the relaxation after photo excitation in a strongly correlated electron system…
