Persistent currents in two dimensions: New regimes induced by the interplay between electronic correlations and disorder
Zoltan Adam Nemeth, Jean-Louis Pichard
Using the persistent current I induced by an Aharonov-Bohm flux in square lattices with random potentials, we study the interplay between electronic correlations and disorder upon…

Effect of a lattice upon an interacting system of electrons in two dimensions: Breakdown of scaling and decay of persistent currents
Houman Falakshahi, Zoltán Ádám Németh, Jean-Louis Pichard
The ground state of an electron gas is characterized by the interparticle spacing to the effective Bohr radius ratio r_s=a/a_B*. For polarized electrons on a two dimensional square…

Andreev-Lifshitz supersolid revisited for a few electrons on a square lattice II
Zoltan Adam Nemeth, Jean-Louis Pichard
In this second paper, using N=3 polarized electrons (spinless fermions) interacting via a U/r Coulomb repulsion on a two dimensional L * L square lattice with periodic boundary con…
