Re-examination of the dependence of the 2 D liquid - Wigner crystal transition density on spin

ORAL

Abstract

Using new diffusion quantum Monte Carlo calculations, we estimate the density of the Wigner crystal transition for spinless fermions, spin 1/2 fermions, spin 3/2 fermions and for bosons in 2 dimensions. We also discuss the possible existence of a colloid phase regime at a density higher than the crystal phase.
