Lattice Models with N=2 Supersymmetry
Paul Fendley, Kareljan Schoutens, Jan de Boer
We introduce lattice models with explicit N=2 supersymmetry. In these interacting models, the supersymmetry generators Q^+ and Q^- yield the Hamiltonian H={Q^+,Q^-} on any graph. T…
Differential equations and duality in massless integrable field theories at zero temperature
P. Fendley, H. Saleur
Functional relations play a key role in the study of integrable models. We argue in this paper that for massless field theories at zero temperature, these relations can in fact be…
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…
Non-equilibrium DC noise in a Luttinger liquid with impurity
P. Fendley, H. Saleur
We compute exactly the non-equilibrium DC noise in a Luttinger liquid with an impurity and an applied voltage. By generalizing Landauer transport theory for Fermi liquids to intera…
Exact perturbative solution of the Kondo problem
P. Fendley, H. Saleur
We explicitly evaluate the infinite series of integrals that appears in the "Anderson-Yuval" reformulation of the anisotropic Kondo problem in terms of a one-dimensional Coulomb ga…
Solving 1d plasmas and 2d boundary problems using Jack polynomials and functional relations
P. Fendley, F. Lesage, H. Saleur
The general one-dimensional ``log-sine'' gas is defined by restricting the positive and negative charges of a two-dimensional Coulomb gas to live on a circle. Depending on charge c…
Exact Theory of Polymer Adsorption in Analogy with the Kondo Problem
P. Fendley, H. Saleur
We conjecture the exact scaling theory for the adsorption of two-dimensional polymers by using boundary S matrices. We compute the boundary free energy (the ``g-function''), study…
