Resistivity of the two-dimensional Bose-Hubbard model at weak coupling
Eduardo O. Rizzatti, Erich J. Mueller
We calculate the weak-coupling resistivity of the two-dimensional Bose Hubbard model, comparing with the more familiar fermionic case. At high temperature the resistivity is linear…

Waterlike density anomaly in fermions
Marco A. Habitzreuter, Eduardo O. Rizzatti, Marcia C. Barbosa
In this work we explore the one-dimensional extended Hubbard model as a fluid system modelling liquid phases of different densities. This model naturally displays two length scales…
