Transient field-resolved reflectometry at 50-100 THz
M. Neuhaus, J. Schötz, M. Aulich +11
Transient field-resolved spectroscopy enables studies of ultrafast dynamics in molecules, nanostructures, or solids with sub-cycle resolution, but previous work has so far concentr…
Time-dependent screening explains the ultrafast excitonic signal rise in 2D semiconductors
Valerie Smejkal, Florian Libisch, Alejandro Molina-Sanchez +2
We calculate the time evolution of the transient reflection signal in an MoS monolayer on a SiO/Si substrate using first-principles out-of-equilibrium real-time methods. Ou…
Localized inter-valley defect excitons as single-photon emitters in WSe
L. Linhart, M. Paur, V. Smejkal +3
Single-photon emitters play a key role in present and emerging quantum technologies. Several recent measurements have established monolayer WSe as a promising candidate for a r…
Ab-initio multi-scale simulation of high-harmonic generation in solids
Isabella Floss, Christoph Lemell, Georg Wachter +5
High-harmonic generation by a highly non-linear interaction of infrared laser fields with matter allows for the generation of attosecond pulses in the XUV spectral regime. This pro…
