Geometric quantum discord and coherence in a dipolar interacting magnetic system
Clebson Cruz, Maron F. Anka, Hamid-Reza Rastegar-Sedehi +1
The study of low-dimensional metal complexes has revealed fascinating characteristics regarding the ground-state crossover shown by spin-gaped systems. In this context, this work e…
Entanglement dynamics of a dc SQUID interacting with a single-mode radiation field
Cleidson Castro, Matheus R. Araújo, Clebson Cruz
In this work, we study the coupling between a superconducting device as a dc SQUID, simulated from an artificial atom with two degrees of freedom, and a single-mode radiation field…
Thermal entanglement and teleportation in a dipolar interacting system
Cleidson Castro, Oscar Duarte, Diego Pires +2
Quantum teleportation, which depends on entangled states, is a fascinating subject and an important branch of quantum information processing. The present work reports the use of a…
Witnessing spin-orbit thermal entanglement in rare-earth ions
O. S. Duarte, C. S. Castro, D. O. Soares-Pinto +1
We explore spin-orbit thermal entanglement in rare-earth ions, based on a witness obtained from mean energies. The entanglement temperature , below which entanglement emerge…
Entanglement dynamics via geometric phases in quantum spin chains
C. S. Castro, M. S. Sarandy
We introduce a connection between entanglement induced by interaction and geometric phases acquired by a composite quantum spin system. We begin by analyzing the evaluation of cycl…
