Angle-resolved photoemission studies of quantum materials

Angle-resolved photoemission (ARPES) has evolved into a precision probe of electronic structure in momentum space of novel quantum materials. This review of a rapidly expanding field summarizes the technical advances leading to an increasing resolution and understanding of quantum materials, including copper- and iron-based superconductors, low-dimensional systems, topological materials, heavy fermions, and many magnetic systems. ARPES is presented as an accessible tool well situated to make advances in our understanding of the electronic structure of novel quantum materials.
