Title: "Spintronics: from coupled spin chains to graphene nanoribbons and molecular spin systems"

Speaker: Dr. Mehdi Zarea, Northwestern University

Abstract: Radical pairs are accounted for quantum effects in biological
systems such as bird magnetic vision. We investigate the quantum
dynamics of the radical pair and its role in the spin polarization
transfer to nearby spins. It is also proposed that the same system might
be used for spin teleportation. In low dimensional systems quantum
fluctuation and strong Coulomb interaction make the spin dynamics more
intriguing. Two examples are presented: frustrated (zigzag) spin chains
and spin-filtered edge states of graphene ribbons.
