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…
Green functions for nearest- and next-nearest-neighbor hopping on the Bethe lattice
M. Kollar, M. Eckstein, K. Byczuk +8
We calculate the local Green function for a quantum-mechanical particle with hopping between nearest and next-nearest neighbors on the Bethe lattice, where the on-site energies may…
Disorder-Driven Non-Fermi Liquid Behavior of Correlated Electrons
E. Miranda, V. Dobrosavljevic
Systematic deviations from standard Fermi-liquid behavior have been widely observed and documented in several classes of strongly correlated metals. For many of these systems, moun…
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…
