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…
Quantum anisotropic Heisenberg chains with superlattice structure: a DMRG study
J. Silva-Valencia, J. C. Xavier, E. Miranda
Using the density matrix renormalization group technique, we study spin superlattices composed of a repeated pattern of two spin-1/2 XXZ chains with different anisotropy parameters…
Non-uniform phases in metals with local moments
Angsula Ghosh, E. Miranda
The two-dimensional Kondo lattice model with both nearest and next-nearest neighbor exchange interactions is studied within a mean-field approach and its phase diagram is determine…
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…
Magnetically-controlled impurities in quantum wires with strong Rashba coupling
R. G. Pereira, E. Miranda
We investigate the effect of strong spin-orbit interaction on the electronic transport through non-magnetic impurities in one-dimensional systems. When a perpendicular magnetic fie…
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…
