4kF response function in the Tomonaga model
Abstract
We calculate the 4kF response function for a one-dimensional Fermi gas using a model containing an offsite interaction V of the Tomonaga form. The approach of Dzyaloshinskii and Larkin extended by Fogedby is employed, and the result is consistent with those of Emery and those of Lee et al.
