We consider the ground state reorganization driven by an increasing nearest
neighbor repulsion U for spinless fermions in a strongly disordered ring. When
U -> 0, the electrons form a glass with Anderson localized states. At half
filling, a regular array of charges (Mott insulator) is pinned by the random
substrate when U -> \infty. Between those two insulating limits, we show that
there is an intermediate regime where the electron glass becomes more liquid
before crystallizing. The liquid-like behavior of the density-density
correlation function is accompanied by an enhancement of the persistent
current.Comment: 5 pages, Latex, uses moriond.sty (included), Contribution to the
