Evidence for a Non-Fermi-Liquid Phase in Ge-Substituted YbRh2Si2
J. Custers, P. Gegenwart, C. Geibel +3
The canonical view of heavy fermion quantum criticality assumes a single quantum critical point separating the paramagnet from the antiferromagnet. However, recent experiments on Y…
Kondo resonance narrowing in d- and f-electron systems
Andriy H. Nevidomskyy, P. Coleman
By developing a simple scaling theory for the effect of Hund's interactions on the Kondo effect, we show how an exponential narrowing of the Kondo resonance develops in magnetic io…
Quantum criticality and the break-up of the Kondo pseudo-potential
Eran Lebanon, P. Coleman
We discuss how Anderson's ideas of nominal and real valence can be incorporated into the current discussion of heavy electron quantum criticality. In the heavy electron phase, the…
Theory Perspective: SCES '05 Vienna
P. Coleman
Over the past decades, research into strongly correlated electron materials that has consistently outperformed our wildest expectations, with new discoveries and radically new theo…
Transport anomalies in a simplified model for a heavy electron quantum critical point
P. Coleman, J. B. Marston, A. J. Schofield
We discuss the transport anomalies associated with the development of heavy electrons out of a neutral spin fluid using the large-N treatment of the Kondo-Heisenberg lattice model.…
Sum Rules and Ward Identities in the Kondo Lattice
P. Coleman, I. Paul, J. Rech
We derive a generalized Luttinger-Ward expression for the Free energy of a many body system involving a constrained Hilbert space. In the large limit, we are able to explicity…
