Theoretical condensed matter physics and computational materials science:
• Novel physics induced by spin-orbit coupling, such as topological insulators, spin splittings (Rashba-type and Dresselhaus-type) and related electronic or optical properties.
• Atomic and electronic structure of crystals, defects, molecules and low-dimensional nanostructures, such as interfaces, heterostructures, graphene, silicene, carbon nanotube and transition-metal dichalcogenides.
• Novel electronic device simulation in nanoelectronics and spintronics, such as (spin-) field effect transistor, negative differential resistance, spin-filter, spin-valve, etc.
