Renormalization group and asymptotic spin-charge separation for chiral luttinger liquids / P. Falco, V. Mastropietro. - In: JOURNAL OF STATISTICAL PHYSICS. - ISSN 0022-4715. - 131:1(2008 Apr), pp. 79-116.
Abstract:
The phenomenon of Spin-Charge separation in non-Fermi liquids is well understood only in certain solvable d=1 fermionic systems. In this paper we furnish the first example of asymptotic Spin-Charge separation in a d=1 nonsolvable model. This goal is achieved using Renormalization Group approach combined with Ward-Identities and Schwinger-Dyson equations, corrected by the presence of a bandwidth cut-offs. Such methods, contrary to bosonization, could be in principle applied also to lattice or higher dimensional systems.
