摘要:

Understanding the mechanism of high temperature superconductivity as in the copper-based compounds discovered in 1986 and

the iron-based compounds discovered in 2008 is a prominent and challenging issue in condensed matter physics. Angle-Resolved

photoemission spectroscopy (ARPES), as a powerful technique to directly probe the electronic structure of materials, has played a

key role in studying high temperature superconductors. In this talk, I will first introduce the principle, history and present status of

photoemission techniques, particularly the latest development of laser-based spin- and angle-resolved photoemission spectroscopy

(ARPES) which has unique advantages such as super-high energy resolution. I will then highlight some recent advances in utilizing

the state-of-the-art ARPES in studying copper-based [1,2] and iron-based [3,4] high temperature superconductors, as well as topological

insulators [5,6].
