^-1-σ (-2≤σ less then -1) that interpolates between the Coulomb potential V_0(x) and the linearly confining potential V_-2(x) of the Schwinger model. In the absence of disorder the ground state is a Wigner crystal when σ≤0. Using bosonization and the nonperturbative functional renormalization group we show that any amount of disorder suppre […] View
