Many Body Diffusion and Interacting Electrons in a Harmonic Confinement

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.Comment: Revised version, submitted to Phys. Rev. B E-mail adresses: [email protected]; [email protected]; [email protected]
