Kondo physics in a dissipative environment
Abstract
We report nonperturbative results for the interacting quantum-critical behavior in a Bose-Fermi Kondo model describing a spin- {1}/{2} coupled both to a fermionic band with a pseudogap density of states and to a dissipative bosonic bath. The model serves as a paradigm for studying the interplay between Kondo physics and low-energy dissipative modes in strongly correlated systems.
