  For intermediate Coulomb energy to Fermi energy ratios $r_s$, spinless
fermions in a two-dimensional random potential form a new quantum phase,
different from the Fermi glass (weakly interacting Anderson localized states)
and the Wigner crystal (regular array of charges pinned by the disorder). The
intermediate phase is characterized by an ordered flow of persistent currents
with a typical value decreasing with excitation energy. Extending finite size
scaling analysis to the many body ground state, we find that electron-electron
interactions can drive the Fermi glass towards an intermediate metallic phase
(Coulomb metal).
