Theory of resonance Raman profiles in transition metal dichalcogenide monolayers: Interference effects due to inter-valley phonon scattering
Daniel Groll, Daniel Wigger, Tilmann Kuhn
The optical properties of monolayer transition metal dichalcogenides (TMDCs) are strongly impacted by exciton-phonon coupling, especially inter-valley scattering in the case of tun…
Phonon-induced Markovian and non-Markovian effects on absorption spectra of moiré excitons in twisted transition metal dichalcogenide bilayers
Daniel Groll, Anton Plonka, Kevin Jürgens +2
The properties of moiré excitons in twisted bilayers of transition metal dichalcogenides (TMDCs) vary significantly with the twist angle, ranging from quasi localized excitons with…
Topical review on acousto-optical Floquet engineering of single-photon emitters
Daniel Groll, Daniel Wigger, Matthias Weiß +6
The combination of solid state single-photon emitters and mechanical excitations on a common platform is a promising approach for the development of hybrid quantum technologies. In…
Fundamentals of heterodyne wave mixing spectroscopy: a tutorial
Daniel Groll, Thilo Hahn, Paweł Machnikowski +3
This tutorial provides a joint theoretical and experimental overview of heterodyne wave mixing spectroscopy, focusing mainly on four-wave mixing (FWM). This powerful and versatile…
Theory of phonon sidebands in the absorption spectra of moiré exciton-polaritons
Kevin Jürgens, Daniel Wigger, Tilmann Kuhn
Excitons in twisted bilayers of transition metal dichalcogenides have strongly modified dispersion relations due to the formation of periodic moiré potentials. The strong coupling…
Spin-dependent exciton-exciton interactions in a mixed lead halide perovskite crystal
Stefan Grisard, Artur V. Trifonov, Thilo Hahn +6
We investigate the two-pulse photon echo response of excitons in the mixed lead halide perovskite crystal \sample in dependence on the excitation intensity and polarization of the…
