摘要: We present numerically exact energy estimates for two-dimensional electrons in a parabolic confinement. By application of an extension the recently introduced many-body diffusion algorithm, ground-state energies are simulated very efficiently. The new algorithm relies on partial antisymmetrization under permutation particle coordinates. A comparison is made with earlier theoretical results that system.
