Probing many-body correlations using quantum-cascade correlation spectroscopy
Lorenzo Scarpelli, Cyril Elouard, Mattias Johnsson +7
The radiative quantum cascade, i.e. the consecutive emission of photons from a ladder of energy levels, is of fundamental importance in quantum optics. For example, the two-photon…
Dynamics of resonantly excited excitons in MoSe and WS single-layers monitored with four-wave mixing
Tomasz Jakubczyk, Miroslav Bartos, Karol Nogajewski +4
We investigate dynamics of resonantly excited excitons in single-layers of MoSe and WS down to 4.5 K. To this end, we measure the delay dependence of the heterodyne four-wa…
99% beta factor and directional coupling of quantum dots to fast light in photonic crystal waveguides determined by hyperspectral imaging
L. Scarpelli, B. Lang, F. Masia +8
Spontaneous emission from excitonic transitions in InAs/GaAs quantum dots embedded in photonic crystal waveguides at 5K into non-guided and guided modes is determined by direct hyp…
Coherence and density dynamics of excitons in a single-layer MoS reaching the homogeneous limit
Tomasz Jakubczyk, Goutham Nayak, Lorenzo Scarpelli +13
We measure the coherent nonlinear response of excitons in a single-layer of molybdenum disulphide embedded in hexagonal boron nitride, forming a -BN/MoS/-BN heterostructu…
Long Exciton Dephasing Time and Coherent Phonon Coupling in CsPbBrCl Perovskite Nanocrystals
Michael A. Becker, Lorenzo Scarpelli, Georgian Nedelcu +7
Fully-inorganic cesium lead halide perovskite nanocrystals (NCs) have shown to exhibit outstanding optical properties such as wide spectral tunability, high quantum yield, high osc…
Resonantly excited exciton dynamics in two-dimensional MoSe monolayers
L. Scarpelli, F. Masia, E. M. Alexeev +4
We report on the exciton and trion density dynamics in a single layer of MoSe, resonantly excited and probed using three-pulse four-wave mixing (FWM), at temperatures from 300K…
