Effective action for phase fluctuations in d-wave superconductors near a Mott transition
Damien Bensimon, Roland Zeyher
Phase fluctuations of a d-wave superconducting order parameter are theoretically studied in the context of high-T cuprates. We consider the model describing layered compo…
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…
Antiferromagnetism and singlet formation in underdoped high-Tc cuprates: Implications for superconducting pairing
Damien Bensimon, Naoto Nagaosa
The extended model is theoretically studied, in the context of hole underdoped cuprates. Based on results obtained by recent numerical studies, we identify the mean field sta…
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…
