Lectures on Non Perturbative Field Theory and Quantum Impurity Problems
H. Saleur
These are lectures presented at the Les Houches Summer School ``Topology and Geometry in Physics'', July 1998. They provide a simple introduction to non perturbative methods of fie…
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…
Hyperelliptic curves for multi-channel quantum wires and the multi-channel Kondo problem
P. Fendley, H. Saleur
We study the current in a multi-channel quantum wire and the magnetization in the multi-channel Kondo problem. We show that at zero temperature they can be written simply in terms…
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…
Self-duality in quantum impurity problems
P. Fendley, H. Saleur
We establish the existence of an exact non-perturbative self-duality in a variety of quantum impurity problems, including the Luttinger liquid or quantum wire with impurity. The fo…
Multiparameter Integrable QFT's with N bosons
Hubert Saleur, Prospero Simonetti
We introduce a new family of integrable theories with bosons and freely adjustable mass parameters. These theories restrict in particular limits to the ``generalized supers…
Boundary Critical Phenomena in the Three-State Potts Model
Ian Affleck, Masaki Oshikawa, Hubert Saleur
Boundary critical phenomena are studied in the 3- State Potts model in 2 dimensions using conformal field theory, duality and renormalization group methods. A presumably complete s…
Boundary flows in minimal models
F. Lesage, H. Saleur, P. Simonetti
We discuss in this paper the behaviour of minimal models of conformal theory perturbed by the operator at the boundary. Using the RSOS restriction of the sine-Gordon model…
Boundary conditions changing operators in non conformal theories
F. Lesage, H. Saleur
Boundary conditions changing operators have played an important role in conformal field theory. Here, we study their equivalent in the case where a mass scale is introduced, in an…
