Perturbation of infra-red fixed points and duality in quantum impurity problems
F. Lesage, H. Saleur
We explain in this paper how a meaningful irrelevant perturbation theory around the infra-red (strong coupling) fixed point can be carried out for integrable quantum impurity probl…

Two-Leg Ladders and Carbon Nanotubes: Exact Properties at Finite Doping
R. Konik, F. Lesage, A. W. W. Ludwig +1
Recently Lin, Balents, and Fisher have demonstrated that two-leg Hubbard ladders and armchair carbon nanotubes renormalize onto the integrable SO(8) Gross-Neveu model. We exploit t…
