Fidelity Between Partial States as Signature of Quantum Phase Transitions
N. Paunkovic, P. D. Sacramento, P. Nogueira +2
We introduce a partial state fidelity approach to quantum phase transitions. We consider a superconducting lattice with a magnetic impurity inserted at its centre, and look at the…
Role of a spin-flip scatterer in a magnetized Luttinger liquid
M. A. N Araujo, J. Berakdar, V. K. Dugaev +1
We study the spin-dependent scattering of charge carriers in a magnetized one dimensional Luttinger liquid from a localized non-homogeneous magnetic field, which might be brought a…
Entanglement signatures of the quantum phase transition induced by a magnetic impurity in a superconductor
P. D. Sacramento, P. Nogueira, V. R. Vieira +1
The insertion of a magnetic impurity in a superconductor induces a first order quantum phase transition as the coupling to the electronic spin density increases. As the transition…
Magnetic impurities in a superconductor: Effect of domain walls and interference
P. D. Sacramento, V. K. Dugaev, V. R. Vieira
We consider the effect of magnetic impurities, modeled by classical spins, in a conventional superconductor. We study their effect on the quasiparticles, specifically on the spin d…
Anomalous Hall effect in a two-dimensional electron gas
Tamara S. Nunner, N. A. Sinitsyn, Mario F. Borunda +7
The anomalous Hall effect in a magnetic two-dimensional electron gas with Rashba spin-orbit coupling is studied within the Kubo-Streda formalism in the presence of pointlike potent…
