Ultrafast evolution of bulk, surface and surface resonance states in photoexcited [Formula: see text]
We use circular dichroism (CD) in time- and angle-resolved photoemission spectroscopy (trARPES) to measure the femtosecond charge dynamics in the topological insulator (TI) [Formula: see text] . We detect clear CD signatures from topological surface states (TSS) and surface resonance (SR) states. In...
