High Harmonic Spectroscopy Probes Lattice Dynamics
Jicai Zhang, Ziwen Wang, Frank Lengers +5
The probing of coherent lattice vibrations in solids has been conventionally carried out using time-resolved transient spectroscopy where only the relative oscillation amplitude ca…
Electron dynamics in a 2D nanobubble: A two-level system based on spatial density
Roberto Rosati, Frank Lengers, Christian Carmesin +5
Nanobubbles formed in monolayers of transition metal dichalcogenides (TMDCs) on top of a substrate feature localized potentials, in which electrons can be captured. We show that th…
Comparison of the semiclassical and quantum optical field dynamics in a pulse-excited optical cavity with a finite number of quantum emitters
K. Jürgens, F. Lengers, D. Groll +3
The spectral and temporal response of a set of quantum emitters embedded in a photonic cavity is studied. Quantum mechanically, such systems can be described by the Tavis-Cummi…
Phonon signatures in spectra of exciton polaritons in transition metal dichalcogenides
Frank Lengers, Tilmann Kuhn, Doris E. Reiter
Embedding a monolayer of a transition metal dichalcogenide in a high-Q optical cavity results in the formation of distinct exciton polariton modes. The polaritons are affected by t…
Phonon-mediated exciton capture in Mo-based transition metal dichalcogenides
F. Lengers, T. Kuhn, D. E. Reiter
Localized excitons play a vital role in the optical response of monolayers of transition metal dichalcogenides and can be exploited as single photon sources for quantum information…
Semiclassical modeling of coupled quantum dot-cavity systems: From polariton-like dynamics to Rabi oscillations
K. Jürgens, F. Lengers, T. Kuhn +1
Semiconductor quantum dots in photonic cavities are strongly coupled light-matter systems with prospective applications in optoelectronic devices and quantum information processing…
Theory of absorption lineshape in monolayers of transition metal dichalcogenides
F. Lengers, T. Kuhn, D. E. Reiter
The linear absorption spectra in monolayers of transition metal dichalcogenides show pronounced signatures of the exceptionally strong exciton-phonon interaction in these materials…
Spatiotemporal dynamics of Coulomb-correlated carriers in semiconductors
F. Lengers, R. Rosati, T. Kuhn +1
When the excitation of carriers in real space is focused down to the nanometer scale, the carrier system can no longer be viewed as homogeneous and ultrafast transport of the excit…
Spatial control of carrier capture in two-dimensional materials: Beyond energy selection rules
Roberto Rosati, Frank Lengers, Doris E. Reiter +1
Transition metal dichalcogenide monolayers have attracted wide attention due to their remarkable optical, electronic and mechanical properties. In these materials local strain dist…
