Explores the concept of time in quantum mechanics, the Heisenberg uncertainty relation, time-resolved photoemission, attosecond time scales, and spin-orbit interaction spectroscopy.
Explores the fundamentals of exchange interactions, including intra-atomic and inter-atomic exchange, spin-orbit coupling, and Dzyaloshinskii-Moryia coupling.
Explores the theory of electric polarization and orbital magnetization in condensed matter physics, focusing on quantum aspects and topological insulators.
