Spin-Polarized Transport on Photo-Asisted Bilayer Graphene Ribbons

We show how both transmission and spin polarization [1,2] behave in bilayer graphene ribbons in contact with a ferromagnetic insulator while a laser is applied to the ribbon. Using a $\pi$-orbital tight-binding model as a low energy approximation [1] and the Tien-Gordon [3] formalism we explore how these systems behave when the ribbon is photo-assisted with a laser. For particular values of the laser parameters, the Fano antiresonance are removed enhancing the transmission while for others spin-polarized transport will arise. \begin{thebibliography}{0} \bibitem{ORCP} P.
