报告内容：

Advanced spectroscopy tools that directly probe the electronic structure and dynamics in quantum materials is essential to the exploration of quantum many-body states. In this talk, Dr. Li will introduce his works using angle-resolved photoemission spectroscopy to directly probe the many-body excitations in the strongly correlated nickelate materials. He will present his research on two major families of nickelate superconductors¬ – ¬the perovskite phase nickelates and the planar nickelates. This research not only reveals the orbital-polarized electronic structure in the two nickelate compounds, but also presents a detailed analysis of the electronic self-energy that uncover the unique electron correlations in these materials.
