The coupling of monochromatic light fields and solids introducesnonequilibrium Floquet states, offering opportunities to create and explore newtopological phenomena. Using combined first-principles and Floquet analysis weshow that one can freely engineer Floquet-Dirac fermions (FDFs) in graphene bytuning the frequency and intensity of linearly polarized light. Not onlytype-II FDFs are created, but they also coexist with type-I FDFs near the Fermilevel. Intriguingly, novel topologically nontrivial edge states connectingtype-I and type-II Floquet-Dirac points emerge in photodriven graphene,providing an ideal channel to realize electron transport between the two typesof Dirac states. Simulating time- and angle-resolved photoelectron spectroscopysuggests that the new coexisting state of type-I and type-II fermions isexperimentally accessible. This work implies that a rich FDF phenomenon can beengineered in atomically thin graphene, hinting for developments of noveloptoelectronic and quantum computing devices.
