✦ Synopsis

A generalized di usion Monte Carlo method for solving the many-body Schr odinger equation on curved manifolds is introduced and used to perform a 'ÿxed-phase' simulation of the integer and fractional quantum-Hall e ect on the Haldane sphere. The e ect of Landau level mixing on the = 1 and = 1 3 energy gaps and the relative stability of spin-polarized and spin-reversed quasielectron excitations are studied using the new method.
