Effect of light-matter interaction on the ballistic conductance of an irradiated dice material

ORAL

Abstract

We derived closed-form analytic expressions for the transmission coefficient of quasiparticles impinging on a square electrostatic potential barrier and step formed by split gates on a dice material which is irradiated by circularly polarized light. A consequence of modifying the states by the dressing field is to suppress Klein tunneling for head-on collision. Our results for transmission are employed in the Landauer-Buttiker formalism to examine the ballistic transport properties for varying barrier widths, incident quasiparticle energy, and light intensity. A comparison is made between our results for dressed and undressed states.
