Wigner molecules in quantum dots: a quantum Monte Carlo study
arXiv:cond-mat/0105452 · doi:10.1103/PhysRevB.65.075309
Abstract
We study two-dimensional quantum dots using the variational quantum Monte Carlo technique in the weak-confinement limit where the system approaches the Wigner molecule, i.e., the classical solution of point charges in an external potential. We observe the spin-polarization of electrons followed by a smooth transition to a Wigner-molecule-like state as the confining potential is made weaker.
