Abstract
For intermediate Coulomb energy to Fermi energy ratios , spinless fermions in a random potential form a new quantum phase which is nor a Fermi glass, neither a Wigner crystal. Studying small clusters, we show that this phase gives rise to an ordered flow of enhanced persistent currents, for disorder strength and ratios where a metallic phase has been recently observed in two dimensions.
