Thickness-Dependent Coherent Phonon Frequency in Ultrathin FeSe/SrTiO Films
Shuolong Yang, Jonathan A. Sobota, Dominik Leuenberger +7
Ultrathin FeSe films grown on SrTiO substrates are a recent milestone in atomic material engineering due to their important role in understanding unconventional superconducti…
Classification of Collective Modes in a Charge Density Wave by Momentum-Dependent Modulation of the Electronic Band Structure
D. Leuenberger, J. A. Sobota, S. -L. Yang +7
We present time- and angle-resolved photoemission spectroscopy measurements on the charge density wave system CeTe. Optical excitation transiently populates the unoccupied ba…
Direct characterization of photo-induced lattice dynamics in BaFe2As2
S. Gerber, K. W. Kim, Y. Zhang +21
Ultrafast light pulses can modify the electronic properties of quantum materials by perturbing the underlying, intertwined degrees of freedom. In particular, iron-based superconduc…
Distinguishing bulk and surface electron-phonon coupling in the topological insulator Bi2Se3 using time-resolved photoemission spectroscopy
Jonathan A. Sobota, Shuolong Yang, Dominik Leuenberger +6
We report time- and angle-resolved photoemission spectroscopy measurements on the topological insulator Bi2Se3. We observe oscillatory modulations of the electronic structure of bo…
Phase Fluctuations and the Absence of Topological Defects in Photo-excited Charge Ordered Nickelate
W. S. Lee, Y. D. Chuang, R. G. Moore +32
The dynamics of an order parameter's amplitude and phase determines the collective behaviour of novel states emerged in complex materials. Time- and momentum-resolved pump-probe sp…
Ultrafast Optical Excitation of a Persistent Surface-State Population in the Topological Insulator Bi2Se3
Jonathan A. Sobota, Shuolong Yang, James G. Analytis +4
Using femtosecond time- and angle- resolved photoemission spectroscopy, we investigated the nonequilibrium dynamics of the topological insulator Bi2Se3. We studied p-type Bi2Se3, i…
