Abstract
Using the persistent current carried by a few particles in
square lattices with random potentials, one shows that the interplay
between electronic correlations and disorder can give rise to many regimes.
The difference between the continuum and the lattice regimes will be
underlined. The quantum melting of the electron solid will be revisited,
and possible consequences concerning the two-dimensional metal-insulator
transition will be discussed.
