Hamiltonian Description of Composite Fermions: Calculation of Gaps

Mesoscale and Nanoscale Physics 2009-10-31 v2

Abstract

We analytically calculate gaps for the 1/3, 2/5, and 3/7 polarized and partially polarized Fractional Quantum Hall states based on the Hamiltonian Chern-Simons theory we have developed. For a class of potentials that are soft at high momenta (due to the finite thickness of the sample) we find good agreement with numerical and experimental results.
