We calculate the low-energy tunneling density of states nu(epsilon,T) of an N-channel disordered wire, taking into account the electron-electron interaction nonperturbatively. The finite scattering rate 1/tau results in a crossover from the Luttinger liquid behavior at higher energies, nu proportional to epsilon(alpha), to the exponential dependence nu(epsilon,T = 0) proportional to exp(-epsilon*/epsilon) at low energies, where epsilon* proportional to 1/(Ntau). At finite temperature T, the… CONTINUE READING
