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…
Coherent dynamics of individual excitons in a quantum dot embedded in a nanopost
Maxime Gaignard, Karolina Ewa Polczynska, Niels Gregersen +5
We measured coherent ultrafast dynamics of exciton complexes in a single strongly-confined InAs quantum dot embedded in a GaAs nanopost. Such a photonic structure combines a wave g…
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…
Nanoscale resolved mapping of the dipole emission of hBN color centers with a scattering-type scanning near-field optical microscope
Iris Niehues, Daniel Wigger, Korbinian Kaltenecker +11
Color centers in hexagonal boron nitride (hBN) are promising candidates as quantum light sources for future technologies. In this work, we utilize a scattering-type near-field opti…
