Mutual Exclusion Statistics Between Quasiparticles in the Fractional   Quantum Hall Effect
  In this paper we propose a new assignment for mutual exclusion statistics between quasielectrons and quasiholes in the fractional quantum Hall effect. In addition to providing numerical evidence for this assignment, we show that the physical origin of this mutual statistics is a novel hard-core constraint due to correlation between the distinguishable vortex-like quasiparticles.
