Abstract

We consider a model of a Kondo-like impurity interacting with a band of fermions for which the density of states is zero or small near the Fermi energy. Renormalization-group arguments and a large-degeneracy technique are used to demonstrate that this model has a nontrivial zero-temperature phase transition at a finite coupling constant, in contrast to the zero-coupling-constant transition of the ordinary Kondo model. Possible experimental realizations of this model include anisotropic superconductors, narrow gap semiconductors, and systems with flux phases.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
