Charge transport in the Hubbard model at high temperatures: triangular versus square lattice
A. Vranic, J. Vucicevic, J. Kokalj +4
High-temperature bad-metal transport has been recently studied both theoretically and in experiments as one of the key signatures of strong electronic correlations. Here we use the…
The perils of minimal coupling to electromagnetic field in quantum many-body systems
Jan Skolimowski, Adriano Amaricci, Michele Fabrizio
Consistency with the Maxwell equations determines how matter must be coupled to the electro-magnetic field (EMF) within the minimal coupling scheme. Specifically, if the Hamiltonia…
Mottness collapse without metallisation in the domain walls of triangular-lattice Mott insulator 1T-TaS
Jan Skolimowski, Yaroslav Gerasimenko, Rok Žitko
1T-TaS is a charge-density-wave (CDW) compound with a Mott-insulating ground state. The metallic state obtained by doping, substitution or pulsed charge injection is characteri…
Real-space dynamical mean-field theory of Friedel oscillations in strongly correlated electron systems
B. Chatterjee, J. Skolimowski, K. Makuch +1
We study Friedel oscillations and screening effects of the impurity potential in the Hubbard model. Electronic correlations are accounted for by solving the real-space dynamical me…
Thermodynamic properties of correlated fermions in lattices with spin-dependent disorder
K. Makuch, J. Skolimowski, P. B. Chakraborty +2
Motivated by the rapidly growing possibilities for experiments with ultracold atoms in optical lattices we investigate the thermodynamic properties of correlated lattice fermions i…
