Kondo effect in a fermionic hierarchical model
Giuseppe Benfatto, Giovanni Gallavotti, Ian Jauslin
In this paper, a fermionic hierarchical model is defined, inspired by the Kondo model, which describes a 1-dimensional lattice gas of spin-1/2 electrons interacting with a spin-1/2…
Universality of one-dimensional Fermi systems, II. The Luttinger liquid structure
Giuseppe Benfatto, Pierluigi Falco, Vieri Mastropietro
We complete the proof started in "Universality of one-dimensional Fermi systems, I." of the universal Luttinger liquid relations for a general model of spinning fermions on a latti…
Universality of one-dimensional Fermi systems, I. Response functions and critical exponents
Giuseppe Benfatto, Pierluigi Falco, Vieri Mastropietro
The critical behavior of one-dimensional interacting Fermi systems is expected to display universality features, called Luttinger liquid behavior. Critical exponents and certain th…
Universal Luttinger Liquid Relations in the 1D Hubbard Model
Giuseppe Benfatto, Pierluigi Falco, Vieri Mastropietro
We study the 1D extended Hubbard model with a weak repulsive short-range interaction in the non-half-filled band case, using non-perturbative Renormalization Group methods and Ward…
Drude weight in non solvable quantum spin chains
Giuseppe Benfatto, Vieri Mastropietro
For a quantum spin chain or 1D fermionic system, we prove that the Drude weight D verifies the universal Luttinger liquid relation , where is the susceptibility and…
Universal Relations for Non Solvable Statistical Models
G. Benfatto, P. Falco, V. Mastropietro
We present the first rigorous derivation of a number of universal relations for a class of models with continuously varying indices (among which are interacting planar Ising models…
