Spin Liquid Behavior in Electronic Griffiths Phases
D. Tanaskovic, V. Dobrosavljevic, E. Miranda
We examine the interplay of the Kondo effect and the RKKY interactions in electronic Griffiths phases using extended dynamical mean-field theory methods. We find that sub-Ohmic dis…
Self-generated electronic heterogeneity and quantum glassiness in the high temperature superconductors
C. Panagopoulos, V. Dobrosavljevic
We present a systematic study of the spin and charge dynamics of copper oxide superconductors as a function of carrier concentration . Our results portray a coherent physical pi…
Absence of conventional quantum phase transitions in itinerant systems with disorder
V. Dobrosavljevic, E. Miranda
Effects of disorder are examined in itinerant systems close to quantum critical points. We argue that spin fluctuations associated with the long-range part of the RKKY interactions…
Nonlinear screening theory of the Coulomb glass
S. Pankov, V. Dobrosavljevic
A nonlinear screening theory is formulated to study the problem of gap formation and its relation to glassy freezing in classical Coulomb glasses. We find that a pseudo-gap ("plasm…
Effective model of the electronic Griffiths phase
D. Tanaskovic, E. Miranda, V. Dobrosavljevic
We present simple analytical arguments explaining the universal emergence of electronic Griffiths phases as precursors of disorder-driven metal-insulator transitions in correlated…
