Therefore, this effect is usually undesirable and must be compensated for. However, high gain may be used to overcome the destructive role of anisotropy in order to generate bright two-mode correlated twin-beams. In this work, we provide a rigorous theoretical description of the spatial properties of bright squeezed light in the presence of strong anisotropy. We investigate a single crystal and a system of two crystals with an air gap (corresponding to a nonlinear SU(1,1) interferometer) and demonstrate the generation of bright correlated twin-beams in such configurations at high gain due to anisotropy. We explore the mode structure of the generated light and show how anisotropy, together with crystal spacing, can be used for radiation shaping.","lang":"eng"}],"user_id":"16199"},{"user_id":"16199","title":"Transient subdiffusion via disordered quantum walks","author":[{"last_name":"Geraldi","full_name":"Geraldi, Andrea","first_name":"Andrea"},{"full_name":"De, Syamsundar","first_name":"Syamsundar","last_name":"De"},{"last_name":"Laneve","full_name":"Laneve, Alessandro","first_name":"Alessandro"},{"id":"48188","last_name":"Barkhofen","full_name":"Barkhofen, Sonja","first_name":"Sonja"},{"id":"75127","last_name":"Sperling","full_name":"Sperling, Jan","orcid":"0000-0002-5844-3205","first_name":"Jan"},{"last_name":"Mataloni","full_name":"Mataloni, Paolo","first_name":"Paolo"},{"full_name":"Silberhorn, Christine","first_name":"Christine","id":"26263","last_name":"Silberhorn"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"706"},{"_id":"288"},{"_id":"230"},{"_id":"623"},{"_id":"35"}],"publication":"Physical Review Research","status":"public","date_created":"2021-10-15T16:07:18Z","publication_status":"published","publication_identifier":{"issn":["2643-1564"]},"_id":"26287","date_updated":"2023-04-20T15:06:20Z","doi":"10.1103/physrevresearch.3.023052","language":[{"iso":"eng"}],"type":"journal_article","citation":{"short":"A.

Our scheme is based on optical excitation off resonant to a cavity mode followed by ultrafast control of the electronic states using the time-dependent quantum-confined Stark effect, which then allows for cavity-resonant emission. Our theoretical analysis considers cavity-loss mechanisms, the Stark effect, and phonon-induced dephasing, allowing realistic predictions for finite temperatures.","lang":"eng"}],"type":"journal_article","year":"2021","citation":{"ieee":"D.

It was revealed via electrochemical measurements that one oxidation and two reductions take place. The bandgaps determined via the electrochemical approach are in good agreement with the optical bandgap obtained from the absorption spectra via a Tauc plot. In addition, absorption spectra in dependence of the electrochemical potential were the basis for extensive quantum-chemical calculations of the neutral, monoanionic, and dianionic molecules. For this purpose, calculations based on density functional theory were compared with post-Hartree–Fock methods and the CAM-B3LYP functional proved to be the most reliable choice for the calculation of absorption spectra. Furthermore, spectral features found experimentally could be reproduced with vibronic calculations and allowed to understand their origins. In particular, the two lowest energy absorption bands of the anion are not caused by absorption of two distinct electronic states, which might have been expected from vertical excitation calculations, but both states exhibit a strong vibronic progression resulting in contributions to both bands.","lang":"eng"}],"user_id":"16199","year":"2021","citation":{"bibtex":"@article{Wiebeler_Vollbrecht_Neuba_Kitzerow_Schumacher_2021, title={Unraveling the electrochemical and spectroscopic properties of neutral and negatively charged perylene tetraethylesters}, volume={11}, DOI={10.1038/s41598-021-95551-0}, number={116097}, journal={Scientific Reports}, publisher={Springer Science and Business Media LLC}, author={Wiebeler, Christian and Vollbrecht, Joachim and Neuba, Adam and Kitzerow, Heinz-Siegfried and Schumacher, Stefan}, year={2021} }","mla":"Wiebeler, Christian, et al. “Unraveling the Electrochemical and Spectroscopic Properties of Neutral and Negatively Charged Perylene Tetraethylesters.” Scientific Reports, vol. 11, no. 1, 16097, Springer Science and Business Media LLC, 2021, doi:10.1038/s41598-021-95551-0.","chicago":"Wiebeler, Christian, Joachim Vollbrecht, Adam Neuba, Heinz-Siegfried Kitzerow, and Stefan Schumacher. “Unraveling the Electrochemical and Spectroscopic Properties of Neutral and Negatively Charged Perylene Tetraethylesters.” Scientific Reports 11, no. 1 (2021). https://doi.org/10.1038/s41598-021-95551-0.","apa":"Wiebeler, C., Vollbrecht, J., Neuba, A., Kitzerow, H.-S., & Schumacher, S.
