We report nonperturbative results for the interacting quantum-critical behavior in a Bose–
Fermi Kondo model describing a spin-12 coupled both to a fermionic band with a …

We consider the critical properties of the Bose-Fermi Kondo model, which describes a local
moment simultaneously coupled to a conduction electron band and a fluctuating magnetic …

We extend the numerical renormalization-group method to treat Bose-Fermi Kondo models
(BFKMs) describing a local moment coupled both to a conduction band and to a dissipative …

Quantum dissipation induces a critical destruction of a Kondo screened state, which is of
interest in the contexts of quantum critical heavy fermion metals and magnetic …

Recent studies of the global phase diagram of quantum-critical heavy-fermion metals prompt
consideration of the interplay between the Kondo interactions and quantum fluctuations of …

The phase diagram of the Bose-Fermi Kondo model contains an SU (2)-invariant Kondo-
screened phase separated by a continuous quantum phase transition from a Kondo …

We study the Kondo-Heisenberg model using a fermionic representation for the localized
spins. The mean-field phase diagram exhibits a zero-temperature quantum critical point …

We consider the SU (N)× SU (κN) generalization of the spin-isotropic Bose–Fermi Kondo
model in the limit of large N. There are three fixed points corresponding to a multi-channel …

We address the phenomenon of critical Kondo destruction in pseudogap Bose-Fermi
Anderson and Kondo quantum impurity models. These models describe a localized level …

Antiferromagnetic heavy fermion metals close to their quantum critical points display a
richness in their physical properties unanticipated by the traditional approach to quantum …
