Floquet Majorana Modes in Graphene Quantum Dots

We propose a possible way to realize Floquet Majorana fermions in graphene quantum dots connected by a superconducting island. The effective crossed Andreev reflection and hopping amplitudes between the dots are calculated as a function of system parameters. It is shown that the spin degeneracy is broken when the dots are driven out of phase. This all-electric, highly tunable device could be a realistic platform for uncovering dynamically generated Majorana fermions in graphene system.
