Finite temperature precursors of Mottness in the Fermi Hubbard model
Sayantan Roy, Abhisek Samanta, Nandini Trivedi
We investigate finite-temperature precursors of Mottness in the repulsive Hubbard model above the spin-ordering temperature, using numerically exact determinant quantum Monte Carlo…

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…
