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…
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…
Transition from a strong-coupling fixed point to an intermediate-coupling fixed point in a single-channel SU(N) Kondo model: role of the filling and two-stage screening
Andres Jerez, Mireille Lavagna, Damien 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…
