Kondo screening in unconventional superconductors: The role of anomalous propagators
Lars Fritz, Matthias Vojta
The Kondo effect in superconductors is frequently investigated using the local quasiparticle density of states as sole bath characteristics, i.e., the presence of anomalous propaga…
Phase transitions in the pseudogap Anderson and Kondo models: Critical dimensions, renormalization group, and local-moment criticality
Lars Fritz, Matthias Vojta
The pseudogap Kondo problem, describing quantum impurities coupled to fermionic quasiparticles with a pseudogap density of states, rho(omega) ~ |omega|^r, shows a rich zero-tempera…
Critical theories for the pseudogap Kondo problem
Lars Fritz, Marijana Kircan, Matthias Vojta
We discuss quantum phase transitions in the pseudogap Kondo problem, which describes a magnetic moment coupled to conduction electrons with a power-law density of states, rho(omega…
Upper-critical dimension in a quantum impurity model: Critical theory of the asymmetric pseudogap Kondo problem
Matthias Vojta, Lars Fritz
Impurity moments coupled to fermions with a pseudogap density of states display a quantum phase transition between a screened and a free moment phase upon variation of the Kondo co…
