Study of the 1D anisotropic Kondo necklace model at criticality via an entanglement entropy estimator
A. Saguia
We use an estimator of quantum criticality based on the entanglement entropy to discuss the ground state properties of the 1D anisotropic Kondo necklace model. We found that the T=…

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…
