Few-electron quantum dots and disks in zero magnetic field: Possible indications on a liquid-solid transition

Strongly Correlated Electrons 2009-11-07 v2 Mesoscale and Nanoscale Physics

Abstract

Exact-diagonalization studies of few-electron quantum dots and disks are performed, with the aim to investigate a Wigner cluster -- Fermi liquid crossover in zero magnetic field at varying strength of Coulomb interaction. A clear indication of a transition of a liquid-solid type in the ground state is found in a more adequate quantum-disk model.
