With its direct correspondence to the electronic structure, angle-resolved photoemission spectroscopy (ARPES) is a ubiquitous tool for the study of quantum materials. When ex-tended to the temporal domain, time-resolved ARPES offers the potential to move beyond equilibrium properties, exploring both the unoccupied electronic structure as well as its dy-namical response under ultrafast perturbation. In this talk, I will discuss how time-resolved ARPES can probe the coherence of many-body condensates, from high-temperature super-conductivity to spin-correlation-driven pseudogap and excitonic insulating behavior.
