Optically-induced dressed states in αα materials: electronic and transport properties

ORAL

Abstract

We have obtained the energy dispersion relations and their wave functions for the so-called interacting Floquet states in pseudospin-1 α-T3 materials for various value of the parameter α in the presence of an external off-resonant dressing field. The obtained dressed states and their basic electronic properties significantly depend on the polarization of the applied radiation, while our derived results now depend on both the parameter and the light intensity. The energy subbands become directly dependent on the valley index τ once elliptically polarized irradiation is applied. We have calculated optical and transport conductivities for an irradiated dice lattice, which represents a limiting case of an α-T3 structure for α equal to 1.
