Description
Using an ultrashort pulsed extreme ultraviolet laser as the photon source, angle-resolved photoemission spectroscopy (ARPES) has expanded the study of electronic structure beyond the 3D momentum space and into the temporal domain with femtosecond resolution. This advancement in studying electron dynamics greatly enhances the characterization and identification of exotic phase transitions in novel materials, particularly in charge-ordered low-dimensional materials.
In this talk, I will introduce the time-resolved ARPES implemented at the Artemis facility, along with recent results from the beamline dedicated to this technique. I will also discuss the ongoing upgrade of the materials science end-station, which will include both a momentum microscope and a hemispherical analyzer. This upgrade will maximize the capability and performance of time-resolved ARPES and will be available to UK academics and their collaborators through Laserlab-Europe starting in 2026.
