Query: Characteristics of persistent spin current components in a
  quasi-periodic Fibonacci ring with spin-orbit interactions: Prediction of
  spin-orbit coupling and on-site energy   In the present work we investigate the behavior of all three components of
persistent spin current in a quasi-periodic Fibonacci ring subjected to Rashba
and Dresselhaus spin-orbit interactions. Analogous to persistent charge current
in a conducting ring where electrons gain a Berry phase in presence of magnetic
flux, spin Berry phase is associated during the motion of electrons in presence
of a spin-orbit field which is responsible for the generation of spin current.
The interplay between two spin-orbit fields along with quasi-periodic Fibonacci
sequence on persistent spin current is described elaborately, and from our
analysis, we can estimate the strength of any one of two spin-orbit couplings
together with on-site energy, provided the other is known.
