Abstract:
Impurity scattering is introduced in the Tomonaga model of an interacting one-dimensional Fermi system. The dynamic (frequency-dependent) conductivity is averaged over the random potential resulting from the impurities. To study this function the author exploits connections to two different two-dimensional classical models for which a Kosterlitz-Thouless-like transition is obtained. Thus, the system's conductivity changes from the usual insulating form to the ideal conducting behaviour of free fermions. Whether the system insulates or conducts depends on the sign and the strength of the fermionic interaction in qualitative agreement with the behaviour of the density response function and the pairing susceptibility of the pure system.
