Title: A new look into cuprate superconductors using high-precision photoemission spectroscopy
Over the past three decades, angle-resolved photoemission spectroscopy has contributed extensively to our understanding of the cuprate high-temperature superconductors. Nevertheless, there are key questions awaiting to be addressed through measurements with new levels of precision and control. In this talk, I will present our recent efforts in tackling the following two questions, whether there is a quantum critical point under the superconducting dome, and what is the nature of the superconducting phase transition.
