Effects of spin-orbit coupling on the optical responses of a material — •Tae Yun Kim1, Andrea Ferretti2, and Cheol-Hwan Park11Department of Physics and Astronomy, Seoul National University, Seoul 08826, Korea — 2Centro S3, CNR-Instituto Nanoscienze, 41125 Modena, Italy

The electronic structure of a material involving heavy elements are significantly affected by spin-orbit coupling (SOC). Especially, since SOC allows the manipulation of the spin degree of freedom in a material by using light [1-4], understanding the SOC effects on the optical response is a matter of importance. In this contribution, we calculate and investigate the effects of SOC on the optical responses of a material based on a fully-relativistic pseudopotential method [5-6].
