The bosonic Kondo effect
arXiv:cond-mat/0304489 · doi:10.1103/PhysRevLett.92.140402
Abstract
The Kondo effect is associated with the formation of a many-body ground state that contains a quantum-mechanical entanglement between a (localized) fermion and the free fermions. We show that a bosonic version of the Kondo effect can occur in degenerate atomic Fermi gases near the Feshbach resonance. We also discuss how this bosonic Kondo effect can be observed experimentally.
