Correlated quantum materials host a vast array of emergent electronic phenomena, including high-temperature superconductivity, colossal magnetoresistance, and nanoscale charge / spin ordering, some of which might someday serve as potential platforms for future technologies. One of the grand challenges in this field is understanding precisely how strong interactions affect the electronic structure of these materials and ultimately lead to these exotic properties. I will describe how we utilize angle-resolved photoemission spectroscopy (ARPES), a powerful tool for directly probing the electronic structure and many-body interactions in solids, to investigate a variety of correlated quantum materials particularly unconventional superconductors and correlated magnetic materials. Finally, I will focus on our recent work which has extended this technique to a much broader range of materials, particularly artificially engineered heterostructures grown by molecular beam epitaxy where new emergent electronic states can be synthesized and controlled at the atomic interface between different correlated materials.
