OIST TR-ARPES setup with Xing Zhu — Caption

The time- and angle-resolved photoemission spectroscopy (TR-ARPES) setup at OIST, here with study co-first author Xing Zhu, PhD student in the Femtosecond Spectroscopy Unit. Featuring a proprietary, table-top extreme-UV source emitting bursts at femtosecond intervals (1fs = one millionth of one billionth of a second), this setup captured the first real images of excitons, helped sketch out the evolution of dark excitons, and has now proved the feasibility of excitonic Floquet engineering.
