Electron propagation from a photo-excited surface: implications for time-resolved photoemission

Shuolong Yang, Jonathan A. Sobota, Patrick S. Kirchmann +1

We perform time- and angle-resolved photoelectron spectroscopy on p-type GaAs(110). We observe an optically excited population in the conduction band, from which the time scales of…

Direct Optical Coupling to an Unoccupied Dirac Surface State in the Topological Insulator Bi $_{2}$ Se $_{3}$

Jonathan A. Sobota, Shuolong Yang, Alexander F. Kemper +9

We characterize the occupied and unoccupied electronic structure of the topological insulator Bi $_{2}$ Se $_{3}$ by one-photon and two-photon angle-resolved photoemission spectroscopy an…

Real-time manifestation of strongly coupled spin and charge order parameters in stripe-ordered nickelates via time-resolved resonant x-ray diffraction

Y. D. Chuang, W. S. Lee, Y. F. Kung +27

We investigate the order parameter dynamics of the stripe-ordered nickelate, La $_{1.75}$ Sr $_{0.25}$ NiO $_{4}$ , using time-resolved resonant X-ray diffraction. In spite of distinct spi…
