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…
Random Antiferromagnetic SU(N) Spin Chains
J. A. Hoyos, E. Miranda
We analyze random isotropic antiferromagnetic SU(N) spin chains using the real space renormalization group. We find that they are governed at low energies by a universal infinite r…
Phase Diagram of the Two-Leg Kondo Ladder
J. C. Xavier, E. Miranda, E. Dagotto
The phase diagram of the two-leg Kondo ladder is investigated using computational techniques. Ferromagnetism is present, but only at small conduction electron densities and robust…
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…
Phase diagrams and universality classes of random antiferromagnetic spin ladders
J. A. Hoyos, E. Miranda
The random antiferromagnetic two-leg and zigzag spin-1/2 ladders are investigated using the real space renormalization group scheme and their complete phase diagrams are determined…
