| 英文摘要 | Abstract periodically driven systems can host many interesting phenomena. two-dimensional dirac systems irradiated by circularly polarized light are especially attractive thanks to the special absorption and emission of photons near dirac cones. here, letting the light travel in the two-dimensional plane, we treat the light-driven dirac systems by using a unitary transformation, instead of usual floquet theory, to capture the photon-mediated electronic correlation effects. in this approach, the direct electron–photon interaction terms can be removed and the resulting effective electron–electron interactions can produce important effects. the effective interactions can produce topological band structure in the case of irradiated 2d dirac fermion system, and can lift the energy degeneracy of the dirac cones for irradiated graphene. this method can be applied to other light-driven dirac systems to investigate their photon-mediated electronic effects. these phenomena would be observed with ultraviolet light in some effective two-dimensional dirac systems of honeycomb long-period superstructures. |
