Boundary interactions changing operators and dynamical correlations in quantum impurity problems
F. Lesage, H. Saleur
Recent developments have made possible the computation of equilibrium dynamical correlators in quantum impurity problems. In many situations however, one is rather interested in co…

Tunneling in quantum wires II: A new line of IR fixed points
F. Lesage, H. Saleur, P. Simonetti
In a previous paper, we showed that the problem of tunneling in quantum wires was integrable in the isotropic case . In the present work, we continue the exploration of the…

The Maxwell-Bloch Theory in Quantum Optics and the Kondo Model
A. Leclair, F. Lesage, S. Lukyanov +1
In this letter, the problem of radiation in a fiber geometry interacting with a two level atom is mapped onto the anisotropic Kondo model. Thermodynamical and dynamical properties…
