Evidence for exhaustion in the conductivity of the infinite-dimensional periodic Anderson model
A. N. Tahvildar-Zadeh, M. Jarrell, Th. Pruschke +1
Monte Carlo-maximum entropy calculations of the conductivity of the infinite-dimensional periodic Anderson model are presented. We show that the optical conductivity displays anoma…
"Exhaustion" Physics in the Periodic Anderson Model using Iterated Perturbation Theory
N. S. Vidhyadhiraja, A. N. Tahvildar-Zadeh, Mark Jarrell +1
We discuss the "exhaustion" problem in the context of the Periodic Anderson Model using Iterated Perturbation Theory(IPT) within the Dynamical Mean Field Theory. We find that, desp…
Superconducting Instability in the Periodic Anderson Model
A. N. Tahvildar-Zadeh, M. H. Hettler, M. Jarrell
Employing a quantum Monte Carlo simulation we find a pairing instability in the normal state of the infinite dimensional periodic Anderson model. Superconductivity arises from a no…
Nonlocal Dynamical Correlations of Strongly Interacting Electron Systems
M. H. Hettler, A. N. Tahvildar-Zadeh, M. Jarrell +2
We introduce an extension of the dynamical mean field approximation (DMFA) which retains the causal properties and generality of the DMFA, but allows for systematic inclusion of no…
Low-temperature coherence in the periodic Anderson model: Predictions for photoemission of heavy Fermions
A. N. Tahvildar-Zadeh, M. Jarrell, J. K. Freericks
We present numerically exact predictions of the periodic and single-impurity Anderson models to address photoemission experiments on heavy Fermion systems. Unlike the single impuri…
Protracted Screening in the Periodic Anderson Model
A. N. Tahvildar-Zadeh, M. Jarrell, J. K. Freericks
The asymmetric infinite-dimensional periodic Anderson model is examined with a quantum Monte Carlo simulation. For small conduction band filling, we find a severe reduction in the…
