Strong-disorder renormalization-group study of the one-dimensional tight-binding model
Hossein Javan Mard, J. A. Hoyos, Eduardo Miranda +1
We formulate a strong-disorder renormalization-group (SDRG) approach to study the beta function of the tight-binding model in one dimension with both diagonal and off-diagonal diso…
Correlation amplitude and entanglement entropy in random spin chains
J. A. Hoyos, André P. Vieira, Nicolas Laflorencie +1
Using strong-disorder renormalization group, numerical exact diagonalization, and quantum Monte Carlo methods, we revisit the random antiferromagnetic XXZ spin-1/2 chain focusing o…
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…
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…
