Abstract
A generalized diffusion Monte Carlo method for solving the many-body S chrodinger equation on curved manifolds is introduced and used to perf orm a ''fixed-phase'' simulation of the fractional quantum Hall effect on the Haldane sphere. This new method is used to study the effect of Landau level mixing on the nu = 1/3 energy gap and the relative stabi lity of spin-polarized and spin-reversed quasielectron excitations.
