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…
Intermediate liquid-solid regime near the quantum melting of a two dimensional Wigner molecule
Georgios Katomeris, Jean-Louis Pichard
For intermediate values of the Coulomb energy to Fermi energy ratio , the ground state of a few spinless fermions confined on a two dimensional torus is the quantum superposit…
Critical Quantum Chaos in 2D Disordered Systems with Spin-Orbit Coupling
G. N. Katomeris, S. N. Evangelou
We examine the validity of the recently proposed semi-Poisson level spacing distribution function P(S), which characterizes `critical quantum chaos', in 2D disordered systems with…
