Paired composite fermion wavefunctions
arXiv:0708.2680 · doi:10.1103/PhysRevB.77.075319
Abstract
We construct a family of BCS paired composite fermion wavefunctions that generalize, but remain in the same topological phase as, the Moore-Read Pfaffian state for the half-filled Landau level. It is shown that for a wide range of experimentally relevant inter-electron interactions the groundstate can be very accurately represented in this form.
