WebJul 7, 1993 · The strategy is as follows. First, the modes on either side of the Fermi surface within a cut-off are chosen and a path integral is written to describe them. An RG transformation which eliminates a part of these modes, but preserves the action of the noninteracting system is identified. WebTheory of the Luttinger Liquid 6.1 One-dimensional Fermi systems We will now consider the case of one-dimensional (1D) Fermi systems where the Landau theory fails. The way it fails is quite instructive as it reveals that in 1D these systems are generally at a (quantum) critical point, and it will also teach as valuable lessons on quantum ...
