  • Title: Breaking of particle-hole symmetry by Landau level mixing in the ν=5/2 quantized Hall state.
    Author: Rezayi EH, Simon SH.
    Journal: Phys Rev Lett; 2011 Mar 18; 106(11):116801. PubMed ID: 21469885.
    Abstract:
    We perform numerical studies to determine if the fractional quantum Hall state observed at a filling factor of ν=5/2 is the Moore-Read wave function or its particle-hole conjugate, the so-called anti-Pfaffian. Using a truncated Hilbert space approach we find that, for realistic interactions, including Landau-level mixing, the ground state remains fully polarized and the anti-Pfaffian is strongly favored.
