Kondo lattices with inequivalent local moments: Competitive vs. co-operative Kondo screening
Adel Benlagra, Lars Fritz, Matthias Vojta
While standard heavy fermion metals feature a single spin-1/2 local moment per unit cell, more complicated systems with multiple distinct local moments have been synthesized as wel…
He3 bi-layers as a simple example of de-confinement
Adel Benlagra, Catherine Pépin
We consider the recent experiments on He3 bi-layers, showing evidence for a quantum critical point (QCP) at which the first layer localizes. Using the Anderson lattice in two dimen…
Grüneisen ratio at the Kondo breakdown quantum critical point
K. -S. Kim, A. Benlagra, C. Pépin
We show that the scenario of multi-scale Kondo breakdown quantum critical point (QCP) gives rise to a divergent Grüneisen ratio with an anomalous exponent 0.7. In particular, we fi…
Model of Quantum Criticality in He3 bilayers Adsorbed on graphite
Adel Benlagra, Catherine Pepin
Recent experiments on He3 bilayers adsorbed on Graphite have shown striking quantum critical properties at the point where the first layer localizes. We model this system with the…
