Abstract: Angle-resolved photoemission spectroscopy (ARPES) has been utilized for several decades as a major tool to resolve electronic band structures and fundamental interactions in quantum materials. On the other hand, critical information about quantum materials is hidden above the Fermi level, in the time domain, or in microscopic spatial domains. ARPES experiments combined with femtosecond time resolution and micrometer spatial resolution have garnered tremendous attention in the condensed matter community. In this talk I will introduce our latest development of a multi-resolution photoemission spectroscopy setup which combines meV energy resolution, mA-1 momentum resolution, 35 fs time resolution, and 10 micron spatial resolution. I will use examples of magnetic topological insulators and Fe-based superconductors to demonstrate the novel functionalities that this setup brings.
