Reply to the comment on "Theoretical analysis of the transmission phase shift of a quantum dot in the presence of Kondo correlations"
M. Lavagna, P. Vitushinsky, A. Jerez
In their comment, Aharony, Entin-Wohlman, Oreg and von Delft claimed that the expression we obtained for the phase of the S-matrix does not give back the correct result notably in…
Intermediate coupling fixed point study in the overscreened regime of generalized multichannel SU(N) Kondo models
Damien Bensimon, Andres Jerez, Mireille Lavagna
We study a generalized multichannel single-impurity Kondo model, in which the impurity spin is described by a representation of the SU(N) group which combines bosonic and fermionic…
Theoretical analysis of the transmission phase shift of a quantum dot in the presence of Kondo correlations
A. Jerez, P. Vitushinsky, M. Lavagna
We study the effects of Kondo correlations on the transmission phase shift of a quantum dot coupled to two leads in comparison with the experimental determinations made by Aharonov…
Instability of the Fermi-liquid fixed point in an extended Kondo model
M. Lavagna, A. Jerez, D. Bensimon
We study an extended SU(N) single-impurity Kondo model in which the impurity spin is described by a combination of Abrikosov fermions and Schwinger bosons. Our aim is to describe b…
