Nonequilibrium RKKY interaction in irradiated graphene
Modi Ke, Mahmoud M. Asmar, Wang-Kong Tse
Abstract
This work investigates the indirect exchange interaction between magnetic impurities mediated by irradiated electrons in driven graphene. The authors develop a nonequilibrium theory that elucidates the effects of irradiation on the exchange coupling and demonstrate its tunability via the driving field.
