Phonon impact on optical control schemes of quantum dots: The role of quantum dot geometry and symmetry
S. Lüker, T. Kuhn, D. E. Reiter
Phonons strongly influence the optical control of semiconductor quantum dots. When modeling the electron-phonon interaction in several theoretical approaches the quantum dot geomet…
Comparison of different concurrences characterizing photon-pairs generated in the biexciton cascade in quantum dots coupled to microcavities
Moritz Cygorek, Florian Ungar, Tim Seidelmann +4
We compare three different notions of concurrence to measure the polarization entanglement of two-photon states generated by the biexciton cascade in a quantum dot embedded in a mi…
Coulomb effects on the photo-excited quantum dynamics of electrons in a plasmonic nanosphere
Alexandra Crai, Andreas Pusch, Doris E. Reiter +3
With recent experiments investigating the optical properties of progressively smaller plasmonic particles, quantum effects become increasingly more relevant, requiring a microscopi…
Pure Goldstone mode in the quench dynamics of a confined ultracold Fermi gas in the BCS-BEC crossover regime
P. Kettmann, S. Hannibal, M. D. Croitoru +2
We present a numerical study of the dynamic response of a confined superfluid Fermi gas to a rapid change of the scattering length (i.e., an interaction quench). Based on a fully m…
Influence of quantum dot geometry on p-shell transitions in differently charged quantum dots
Matthias Holtkemper, Doris E. Reiter, Tilmann Kuhn
Absorption spectra of neutral, negatively and positively charged semiconductor quantum dots are studied theoretically. We provide an overview of the main energetic structure around…
Magnetic-optical transitions induced by twisted light in quantum dots
G. F. Quinteiro, D. E. Reiter, T. Kuhn
It has been theoretically predicted that light carrying orbital angular momentum, or twisted light, can be tuned to have a strong magnetic-field component at optical frequencies. W…
