The Crossover between Liquid and Solid Electron Phases in Quantum Dots:   A Large-Scale Configuration-Interaction Study
  We study the crossover between liquid and solid electron phases in a two-dimensional harmonic trap as the density is progressively diluted. We infer the formation of geometrically ordered phases from charge distributions and pair correlation functions obtained via a large scale configuration interaction calculation.
