Andreev-Lifshitz supersolid revisited for a few electrons on a square lattice I
Georgios Katomeris, Franck Selva, Jean-Louis Pichard
In 1969, Andreev and Lifshitz have conjectured the existence of a supersolid phase taking place at zero temperature between the quantum liquid and the solid. In this and a succeedi…
Mesoscopic Wigner crystallization in two dimensional lattice models
Jean-Louis Pichard, Georgios Katomeris, Franck Selva
The quantum-classical crossover from the Fermi liquid towards the Wigner solid is numerically revisited, considering small square lattice models where electrons interact via a Coul…
From the Fermi Liquid Towards the Wigner Solid in Two Dimensions
Jean-Louis Pichard, Giuliano Benenti, Georgios Katomeris +2
The quantum-classical crossover from the Fermi liquid towards the Wigner solid is numerically revisited, considering small square lattice models where electrons interact via a Coul…
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…
