Abstract
The spin-sensitive low-energy states in a parabolic quantum dot with small numbers of electrons are examined by the multilevel blocking Monte Carlo me thod. We quantify the importance of correlations and spin sensitivity by co mparing exact results with the unrestricted Hartree-Fock approximation. Wit h spin polarisation the agreement increases systematically, even for strong interactions. (C) 2000 Elsevier Science B.V. All rights reserved.
