Many Body Diffusion and Interacting Electrons in a Harmonic Confinement
arXiv:cond-mat/0002343 · doi:10.1002/1521-3951(200106)225:2<413::AID-PSSB413>3.0.CO;2-2
Abstract
We present numerically exact energy estimates for two-dimensional electrons in a parabolic confinement. By application of an extension of the recently introduced many-body diffusion algorithm, the ground-state energies are simulated very efficiently. The new algorithm relies on partial antisymmetrization under permutation of particle coordinates. A comparison is made with earlier theoretical results for that system.
