For intermediate Coulomb energy to Fermi energy ratios r_s, spinless fermions in a random potential form a new quantum phase which is different from the Fermi glass and the Wigner crystal. From a numerical study of small clusters, we show that this phase is characterized by an ordered flow of enhanced persistent currents and occurs for r_s values where a metallic phase has been observed in two dimensions.

Abstract

For intermediate Coulomb energy to Fermi energy ratios r_s, spinless fermions in a random potential form a new quantum phase which is different from the Fermi glass and the Wigner crystal. From a numerical study of small clusters, we show that this phase is characterized by an ordered flow of enhanced persistent currents and occurs for r_s values where a metallic phase has been observed in two dimensions.
