Quantum control of exciton wavefunctions in 2D semiconductors
Jenny Hu, Etienne Lorchat, Xueqi Chen +5
Excitons -- bound electron-hole pairs -- play a central role in light-matter interaction phenomena, and are crucial for wide-ranging applications from light harvesting and generati…
High-harmonic generation from artificially stacked 2D crystals
Christian Heide, Yuki Kobayashi, Amalya C. Johnson +4
We report a coherent layer-by-layer high-order harmonic generation (HHG) build-up in artificially stacked transition metal dichalcogenides (TMDC) crystals in their various stacking…
Achiral dielectric metasurfaces for spectral and polarization control of valley specific light emission from monolayer MoS2
Yin Liu, Sze Cheung Lau, Wen-Hui Sophia Cheng +9
Excitons in two-dimensional transition metal dichalcogenides have a valley degree of freedom that can be optically accessed and manipulated for quantum information processing. Here…
Atom-Specific Probing of Electron Dynamics in an Atomic Adsorbate by Time-Resolved X-ray Spectroscopy
Simon Schreck, Elias Diesen, Martina Dell'Angela +25
The electronic excitation occurring on adsorbates at ultrafast time scales from optical lasers that initiate surface chemical reactions is still an open question. Here, we report t…
X-ray Free Electron Laser Studies of Electron and Phonon Dynamics of Graphene Adsorbed on Copper
Hirohito Ogasawara, Han Wang, Jörgen Gladh +23
We report optical pumping and X-ray absorption spectroscopy experiments at the PAL free electron laser that directly probe the electron dynamics of a graphene monolayer adsorbed on…
Floquet engineering of strongly-driven excitons in monolayer tungsten disulfide
Yuki Kobayashi, Christian Heide, Amalya C. Johnson +4
Interactions of quantum materials with strong-laser fields can induce exotic nonequilibrium electronic states. Monolayer transition-metal dichalcogenides, a new class of direct-gap…
