Charged excitations of the chiral spin liquid

Abstract

We propose specific wave functions for the charged, spinless excitations hypothesized to exist in chiral spin liquids and show, in the context of the t-J Hamiltonian, that their variational energy and mobility are superior to those of ordinary holes. We find that these quantities limit to finite values as the amount of chirality in the ground state diminishes to zero, but that the statistics become abruptly ill defined in this limit.
