What is the signature of a trion in photoemission?
Jinyuan Wu, Zachary H. Withers, Thomas K. Allison +1
Recent advances in time- and angle-resolved photoemission spectroscopy (tr-ARPES) allow for the probing of multiparticle excited-states in reciprocal space. While neutral two-parti…

Direct Observation of Massless Excitons and Linear Exciton Dispersion
Luna Y. Liu, Steffi Y. Woo, Jinyuan Wu +3
Excitons -- elementary excitations formed by bound electron-hole pairs -- govern the optical properties and excited-state dynamics of materials. In two-dimensions (2D), excitons ar…
