Griffiths phases in the strongly disordered Kondo necklace model
Tatiana G. Rappoport, Beatriz Boechat, Andreia Saguia +1
The effect of strong disorder on the one-dimensional Kondo necklace model is studied using a perturbative real-space renormalization group approach which becomes asymptotically exa…
Role of Disorder on the Quantum Critical Point of a Model for Heavy Fermions
T. G. Rappoport, A. Saguia, B. Boechat +1
A zero temperature real space renormalization group (RG) approach is used to investigate the role of disorder near the quantum critical point (QCP) of a Kondo necklace (XY-KN) mode…
Phase diagram of the Kondo necklace: a mean-field renormalization group approach
Tatiana G. Rappoport, M. A. Continentino
In this paper we investigate the magnetic properties of heavy fermions in the antiferromagnetic and dense Kondo phases in the framework of the Kondo necklace model. We use a mean f…
