Phys. Rev. Lett. 85, 2781–2784 (2000)Interacting Particles as neither Bosons nor Fermions: A Microscopic Origin for Fractional Exclusion StatisticsReceived 17 December 1999; published in the issue dated 25 September 2000 We study a quantum liquid of particles interacting via a long-ranged two-body potential in three dimensions where the original particles are supposed to be either bosons or fermions. We show that such liquids exhibit the nature of a quantum liquid with fractional exclusion statistics. In both quantum liquids enlarged pseudo-Fermi surfaces are formed from bosons and fermions, although with different excitations. Hence, we conclude that the microscopic origin of exclusion statistics comes from the nature of long-ranged two-body interactions between the particles. © 2000 The American Physical Society URL:
