Abstract

The novel method proposed by one of the authors to calculate exactly the response functions of the one-dimensional Tomonaga model is described in more detail. The method is generalized for the case of a system of coupled chains where both the intrachain and interchain interactions have forward scattering components only. The model does not show real phase transition at any finite temperature indicating that the interchain backward scattering or hopping is needed to have an ordering of the chains at finite temperature.
