RETRACTED ARTICLE: Investigation of Quantum Correlations of Electron Spins of Cooper Pair in a Superconductor Under Magnetic Field Effect

Abstract
In this study, quantum entanglement measures such as concurrence and quantum discord of an s-wave superconductor under the influence of a magnetic field were investigated. This weak magnetic field is considered as a first-order perturbation in the two-particle Green's function and anomalous Green's function by using Bogoliubov equations, and then the perturbed two-electron spin-space density matrix (TESSDM) was calculated. Entanglement values...
