Optical control of electrons in a Floquet topological insulator
Daniel M. B. Lesko, Tobias Weitz, Simon Wittigschlager +4
Light-dressed materials hold enormous potential for generating new electronic properties. The band structure resulting from light-dressing can exhibit starkly different quantum and…
Strong-Field Bloch Electron Interferometry for Band Structure Retrieval
Tobias Weitz, Christian Heide, Peter Hommelhoff
When Bloch electrons in a solid are exposed to a strong optical field, they are coherently driven in their respective bands where they acquire a quantum phase as the imprint of the…
Giant room-temperature nonlinearities from a monolayer Janus topological semiconductor
Jiaojian Shi, Haowei Xu, Christian Heide +16
Nonlinear optical materials possess wide applications, ranging from terahertz and mid-infrared detection to energy harvesting. Recently, the correlations between nonlinear optical…
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…
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…
Light-field control of real and virtual charge carriers
Tobias Boolakee, Christian Heide, Antonio Garzón-Ramírez +3
Light-driven electronic excitation is a cornerstone for energy and information transfer. In the interaction of intense and ultrafast light fields with solids, electrons may be exci…
