Scaling behavior of an Anderson impurity close to the Mott-Anderson transition
M. C. O. Aguiar, V. Dobrosavljevic, E. Abrahams +1
The scaling behavior of Anderson impurity models each of which with a different site energy epsilon_i is examined close to the Mott-Anderson transition. Depending on the impurity e…
Effects of disorder on the non-zero temperature Mott Transition
M. C. O. Aguiar, V. Dobrosavljevic, E. Abrahams +1
The physics of the metal-insulator coexistence region near the non-zero temperature Mott transition is investigated in presence of weak disorder. We demonstrate that disorder reduc…
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…
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…
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…
Temperature dependent transport of correlated disordered electrons: elastic vs. inelastic scattering
M. C. O. Aguiar, E. Miranda, V. Dobrosavljevic +2
Temperature dependent transport of disordered electronic systems is examined in the presence of strong correlations. In contrast to what is assumed in Fermi liquid approaches, fini…
