Features of renormalization induced by interaction in one-dimensional transport

One-dimensional interacting electrons in a quantum wire connected to reserv oirs are studied theoretically. The difference in the Tomonaga-Luttinger in teraction constants between the wire (g) and reservoirs (g(infinity)) produ ces the cross correlation between the right- and left-going chiral componen ts of the charge-density wave field. The low-energy asymptotics of this fie ld correlator, which is determined by (g) and (g(infinity)), specifies reno rmalization of physical quantities. We have found that charge of the carrie rs in the shot noise is determined by g(infinity) (no renormalization for t he Fermi liquid reservoirs) at any energy, meanwhile the factor g renormali zing the charge and spin susceptibilities emerges in the threshold structur es at some rational fillings.
