Fractional Rashba-induced quantum correlations and their role in achieving steerability in nanowires

Abstract The dynamics of quantum correlations, steerability, and the coherence of the evolution of a fractional nanowire state are analyzed for a system comprising two electrons interacting with an orbital-spin system through Rashba interaction. The results reveal that the initial state configuration and fractional order act as effective control parameters for enhancing these physical quantities. Preparing the electronic system in an entangled state and the orbital system in an excited state ensures sustained quantum correlations during time evolution. For small fractional order values, the upper bounds of steerability are increased, although the time for steering to decay is shortened. The influence of magnetic field strength, spin–orbit coupling, and confinement potential parameters on improving these measures depends on whether the orbital system is initially prepared in an excited state or a vacuum state.
