Fluctuation-induced first order transition due to Griffiths anomalies of the Cluster glass phase
Matthew J. Case, Vlad Dobrosavljevic
In itinerant magnetic systems with disorder, the quantum Griffiths phase at T=0 is unstable to formation of a cluster glass (CG) of frozen droplet degrees of freedom. In the absenc…

Quantum Critical Behavior of the Cluster Glass Phase
Matthew J. Case, V. Dobrosavljevic
In disordered itinerant magnets with arbitrary symmetry of the order parameter, the conventional quantum critical point between the ordered phase and the paramagnetic Fermi-liquid…
