Explores the theory of electric polarization and orbital magnetization in condensed matter physics, focusing on quantum aspects and topological insulators.
Explores electron behavior in an electron gas and the periodic arrangement of atoms in crystalline solids, along with density of states in various dimensions and energy bands.
Explores the concept of time in quantum mechanics, the Heisenberg uncertainty relation, time-resolved photoemission, attosecond time scales, and spin-orbit interaction spectroscopy.
