On the applicability of bosonization and the Anderson-Yuval methods at the strong-coupling limit of quantum impurity problems
L. Borda, A. Schiller, A. Zawadowski
The applicability of bosonization and the Anderson-Yuval (AY) approach at strong coupling is investigated by considering two generic impurity models: the multichannel interacting r…
Friedel oscillations and the Kondo screening cloud
Ian Affleck, Laszlo Borda, Hubert Saleur
We show that the long distance charge density oscillations in a metal induced by a weakly coupled spin-1/2 magnetic impurity exhibiting the Kondo effect are given, at zero temperat…
Inelastic scattering from quantum impurities
G. Zarand, L. Borda
We review the non-perturbative theoretical framework set up recently to compute the inelastic scattering cross section from quantum impurities [G. Zaránd {\it et al.}, Phys. Rev. L…
Theory of inelastic scattering from quantum impurities
L. Borda, L. Fritz, N. Andrei +1
We use the framework set up recently to compute non-perturbatively inelastic scattering from quantum impurities [G. Zaránd {\it et al.}, Phys. Rev. Lett. {\bf 93}, 107204 (2004)] t…
Theory of a resonant level coupled to several conduction electron channels in equilibrium and out-of-equilibrium
Laszlo Borda, Karoly Vladar, Alfred Zawadowski
The spinless resonant level model is studied when it is coupled by hopping to one of the arbitrary number of conduction electron channels. The Coulomb interaction acts between the…
Absorption and Emission in quantum dots: Fermi surface effects of Anderson excitons
R. W. Helmes, M. Sindel, L. Borda +1
Recent experiments measuring the emission of exciton recombination in a self-organized single quantum dot (QD) have revealed that novel effects occur when the wetting layer surroun…
