Abstract

We calculate the low-energy tunneling density of states ν(ε, T) of an N-channel disordered wire, taking into account the electron-electron interaction nonperturbatively. The finite scattering rate 1/τ results in a crossover from the Luttinger liquid behavior at higher energies, ν∝εα, to the exponential dependence ν(ε, T = 0) ∝ exp(ε*/ε) at low energies, where ε * ∝ 1/(Nτ). At finite temperature T, the tunneling density of states depends on the energy through the dimensionless variable ε/√ε*T. At the Fermi level ν(ε = 0, T) ∝ (− √ε*/t).
