LandauLevel Mixing and ParticleHole Symmetry Breaking for Spin Transitions in the Fractional Quantum Hall Effect
Here, the spin transitions in the fractional quantum Hall effect provide a direct measure of the tiny energy differences between differently spinpolarized states, and thereby serve as an extremely sen sitive test of the quantitative accuracy of the theory of the fractional quantum Hall effect, and, in particular, of the role of Landaulevel mixing in lifting the particlehole symmetry. We report on an accurate quantitative study of this physics, evaluating the effect of Landaulevel mixing in a nonperturbative manner using a fixedphase diffusion Monte Carlo method. We find excellent agree ment between our calculated critical Zeeman energies and the experimentally measured values. In particular, we find, as also do experiments, that the critical Zeeman energies for fractional quantum Hall states at filling factors ν = 2–n/(2n±1) are significantly higher than those for ν = n/(2n±1), a quantitative signature of the lifting of particlehole symmetry due to Landaulevel mixing.
