报告摘要：Photoelectric Effect, as formulated in his 1905 landmark paper, is among the most debated ideas of Albert Einstein. Despite its early controversy, photoelectric effect emerged as a pillar for the establishment of quantum mechanics, and has been an engine driving a century of discovery and innovation. In this talk, I will discuss the development of photoemission as a many-body spectroscopy derived from photoelectric effect. I will survey the advances in energy, momentum, spin and time resolution; and its match with frontier physics problems, in-situ materials synthesis and theoretical simulation. I will showcase recent results from high temperature superconductors and topological insulators. In particular, I will address the issue of pseodogap and its intertwined relationship with superconductivity.
