  • Title: Non-Abelian states with negative flux: a new series of quantum Hall states.
    Author: Jolicoeur T.
    Journal: Phys Rev Lett; 2007 Jul 20; 99(3):036805. PubMed ID: 17678311.
    Abstract:
    By applying the idea of parafermionic clustering to composite bosons with positive as well as negative flux, a new series of trial wave functions to describe fractional quantum Hall states is proposed. These states compete at filling factors nu=k/(3k+/-2) with other ground states like stripes or composite-fermion states. These series contain all the states recently discovered by Pan et al. [Phys. Rev. Lett. 90, 016801 (2003)10.1103/Phys. Rev. Lett. 90, 016801(2003)] including the even-denominator cases. Exact diagonalization studies on the sphere and torus point to their relevance for nu=3/7, 3/11, and 3/8.
