Sign changes of the thermoelectric transport coefficient across the metal-insulator crossover in the doped Fermi Hubbard model
Sayantan Roy, Abhisek Samanta, Nandini Trivedi
We investigate the doping-dependence of the Seebeck coefficient, as calculated from the Kelvin formula, for the Fermi Hubbard model using determinantal quantum Monte Carlo simulati…

Signatures of metal to insulator crossover in the repulsive Fermi Hubbard model through static correlations
Sayantan Roy, Sameed Pervaiz, Thereza Paiva +1
Cold atom systems provide a rich platform to realize strongly interacting condensed matter systems, and recent progress in fluorescence imaging technique has enabled identification…
