Role of a parallel magnetic field in two dimensional disordered clusters containing a few correlated electrons
Franck Selva, Jean-Louis Pichard
An ensemble of 2d disordered clusters with a few electrons is studied as a function of the Coulomb energy to kinetic energy ratio r_s. Between the Fermi system (small r_s) and the…

Coulomb repulsion versus Hubbard repulsion in a disordered chain
Franck Selva, Jean-Louis Pichard
We study the difference between on site Hubbard and long range Coulomb repulsions for two interacting particles in a disordered chain. While Hubbard repulsion can only yield weak c…

Persistent currents for Coulomb interacting electrons on 2d disordered lattices: Sign and interaction dependence in the Wigner crystal regime
Franck Selva, Dietmar Weinmann
A Wigner crystal structure of the electronic ground state is induced by strong Coulomb interactions at low temperature in clean or disordered two-dimensional (2d) samples. For ferm…
