The band structure and the transport properties of graphene are known to be deeply modified by strong electromagnetic fields. Here we experimentally demonstrate, using an engineered optical waveguide lattice as a model system for ac-driven graphene, the partial and complete collapse of valence and conduction quasi-energy bands corresponding to linearly- and circularly-polarized monochromatic light irradiation, respectively.

Abstract
The band structure and the transport properties of graphene are known to be deeply modified by strong electromagnetic fields. Here we experimentally demonstrate, using an engineered optical waveguide lattice as a model system for ac-driven graphene, the partial and complete collapse of valence and conduction quasi-energy bands corresponding to linearly- and circularly-polarized monochromatic light irradiation, respectively.File in questo prodotto:
