Quantum Hall Fluids on the Haldane Sphere: A Diffusion Monte Carlo Study
arXiv:cond-mat/9707251 · doi:10.1103/PhysRevLett.79.5286
Abstract
A generalized diffusion Monte Carlo method for solving the many-body Schrödinger equation on curved manifolds is introduced and used to perform 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 $ν=1/3$ energy gap and the relative stability of spin-polarized and spin-reversed quasielectron excitations.
