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…
