Incipient quantum melting of the one-dimensional Wigner lattice
S. Fratini, B. Valenzuela, D. Baeriswyl
A one--dimensional tight--binding model of electrons with long--range Coulomb interactions is studied in the limit where double site occupancy is forbidden and the Coulomb coupling…

Dynamical mean field theory of small polaron transport
S. Fratini, S. Ciuchi
We present a unified view of the transport properties of small-polarons in the Holstein model at low carrier densities, based on the Dynamical Mean Field Theory. The nonperturbativ…
