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…

Kosterlitz-Thouless Transition Line for the Two Dimensional Coulomb Gas
Pierluigi Falco
With a rigorous renormalization group approach, we study the pressure of the two dimensional Coulomb Gas along a small piece of the Kosterlitz-Thouless transition line, i.e. the bo…
