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…

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…
