From Luttinger liquid to Altshuler-Aronov anomaly in multichannel quantum wires

A crossover theory connecting Altshuler-Aronov electron-electron interaction corrections and Luttinger liquid behavior in quasi-one-dimensional disordered conductors has been formulated. Based on an interacting nonlinear sigma model, we compute the tunneling density of states and the interaction correction to the conductivity, covering the full crossover.
