Quantum Time: Spin-Orbit Interaction and Topology

This lecture delves into the concept of time in quantum mechanics, exploring its definition from historical perspectives and its role as a classical parameter. The discussion progresses to the Heisenberg uncertainty relation, Fourier transform, and the challenges in defining time zero. The lecture also touches on the nature of time in entanglement and the implications of instantaneous coupling. Furthermore, it explores time-resolved photoemission, attosecond time scales, and the measurement of absolute time scales in photoemission. The lecture concludes with insights into spin-orbit interaction spectroscopy, topological phases, and the influence of correlations in solid-state physics.
