Splitting of the circular polarization components of the optical\nmodes induced by photonic RD SOC is observed experimentally in momentum space.\nBy applying an ultraviolet light beam, we control the spatial molecular\norientation through a photochemical reaction and with that we control the\nenergies of the photonic modes. This way we realize a reversible conversion of\nspin-splitting of the optical modes with different energies, leading to an\noptically controlled switching between circularly and linearly polarized\nemission from our device.

For resonant optical\r\nexcitation, we further find that the optical nonlinearity leads to a\r\nmultistability of different edge states. This includes topologically protected\r\nedge states evolved directly from individual linear eigenstates as well as\r\nadditional edge states that originate from nonlinearity-induced localization of\r\nbulk states. Extending the system into two dimensions (2D) by stacking\r\nhorizontal DW chains in the vertical direction, we also create 2D multi-wave\r\nlattices.

Ein möglicher Grund hierfür könnte neben organisatorischen Herausforderungen auch in einer geringen Akzeptanz von Eigenvideografien durch Lehramtsstudierende liegen. Um besser abschätzen zu können, mit welchen Voraussetzungen affektiv-emotionaler Art bei einer breiteren Implementierung im Lehramtsstudium gerechnet werden kann, wurden N = 938 Lehramtsstudierende im Masterstudium an der Universität Paderborn zu ihren Emotionen und Bereitschaften zur Arbeit mit Eigenvideografien befragt. Dabei wurde auch erfasst, wie sich diese je nach bestehenden\r\nErfahrungen zur Arbeit mit Videografien unterscheiden. In den Ergebnissen zeigen sich kaum affektiv-emotionale Reaktionen zur Eigenvideografie, und wenn, vor allem Gefühle der Unsicherheit. Zu beachten ist, dass zwar bei gut der Hälfte der Studierenden eine eher hohe generelle Bereitschaft zur Eigenvideografie besteht, eine konkrete Intention bzw. eine konkrete Volition zur Videografie aber geringer ist. Die ca. 10 % der Studierenden mit Eigenvideografieerfahrung im Studium zeigen erwartungsgemäß höhere Bereitschaften, aber unerwartet keine signifikant positiveren Emotionen. Insgesamt verdeutlichen die Ergebnisse, dass bzgl. der Akzeptanz der Studierenden ein höheres Potenzial zur Implementation von Eigenvideografien im Studium vorliegt, als aktuell ausgeschöpft wird.","lang":"ger"}],"date_created":"2023-01-10T13:06:03Z","department":[{"_id":"33"},{"_id":"386"},{"_id":"586"}],"type":"journal_article","keyword":["Lehrerbildung","Videografie","Praxissemester","Emotionen","Akzeptanz"],"author":[{"id":"4245","last_name":"Vogelsang","orcid":"0000-0002-5804-1855","first_name":"Christoph","full_name":"Vogelsang, Christoph"},{"id":"44191","full_name":"Pollmeier, Pascal","first_name":"Pascal","last_name":"Pollmeier"},{"full_name":"Gockeln, Theresa","last_name":"Gockeln","first_name":"Theresa"},{"full_name":"Rogge, Tim","last_name":"Rogge","first_name":"Tim"}],"year":"2023","title":"Zu unangenehm, zu viel Aufwand oder keine Möglichkeit? – Emotionen und Bereitschaft von Lehramtsstudierenden zur Videografie eigenen Unterrichts","intvolume":"        13","article_type":"original","date_updated":"2025-01-17T11:33:44Z","publication_status":"published","language":[{"iso":"ger"}],"main_file_link":[{"open_access":"1","url":"https://link.springer.com/article/10.1007/s35834-022-00378-y#citeas"}],"doi":"10.1007/s35834-022-00378-y","citation":{"ieee":"C.

To elucidate the origin of the ohmic part of the spectrum, activated carbon electrodes were prepared with different contents of polyacrylic acid as binder. Their impedance spectra and cyclic voltammograms were recorded using sulfuric acid of five different concentrations as the electrolyte. To distinguish electrolyte resistance and resistances related to the activated carbon layer of the electrode, the specific electrolyte conductivity was independently measured and compared against the ohmic part of the electrochemical impedance spectra (EIS). The capacitive cyclic voltammograms show larger resistive contributions with higher scan rate and lower electrolyte conductivity. Comparing the ohmic part of the EIS to the specific resistance of the electrolyte, a linear function with no statistically significant offset was found. The ohmic part of the EIS, thus, reflects the electrolyte resistance, not that of the carbon electrode.","lang":"eng"}],"date_created":"2025-12-03T15:58:28Z","keyword":["electrochemical impedance spectroscopy","supercapacitors","carbon"],"type":"conference","department":[{"_id":"985"}],"title":"Assessment of the Physicochemical Meaning of the Ohmic Series Resistance Observed for High Frequencies in Electrochemical Impedance Spectra","status":"public","year":"2023","author":[{"id":"117727","full_name":"Reinke, Sebastian","first_name":"Sebastian","last_name":"Reinke"},{"last_name":"Khamitsevich","first_name":"Vera","full_name":"Khamitsevich, Vera"},{"first_name":"Oliver","last_name":"Röth","full_name":"Röth, Oliver","id":"117786"},{"last_name":"Linnemann","orcid":"0000-0001-6883-5424","first_name":"Julia","full_name":"Linnemann, Julia","id":"116779"}],"publication_status":"published","date_updated":"2026-01-19T15:40:41Z","language":[{"iso":"eng"}],"_id":"62812","publisher":"IEEE","user_id":"116779","doi":"10.1109/iwis61214.2023.10302764"},{"doi":"10.1103/physrevresearch.5.043158","main_file_link":[{"url":"https://journals.aps.org/prresearch/pdf/10.1103/PhysRevResearch.5.043158","open_access":"1"}],"article_number":"043158","language":[{"iso":"eng"}],"date_updated":"2026-02-01T13:21:22Z","publication_status":"published","intvolume":"         5","year":"2023","title":"Phase sensitivity of spatially broadband high-gain SU(1,1) interferometers","author":[{"id":"55907","first_name":"Dennis","orcid":"0009-0007-5654-5412","last_name":"Scharwald","full_name":"Scharwald, Dennis"},{"id":"344","full_name":"Meier, Torsten","first_name":"Torsten","last_name":"Meier","orcid":"0000-0001-8864-2072"},{"full_name":"Sharapova, Polina","last_name":"Sharapova","first_name":"Polina"}],"publication_identifier":{"issn":["2643-1564"]},"type":"journal_article","department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"293"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"623"},{"_id":"27"}],"date_created":"2024-08-30T04:48:05Z","issue":"4","publication":"Physical Review Research","user_id":"55907","volume":5,"publisher":"American Physical Society (APS)","_id":"55900","status":"public","oa":"1","project":[{"name":"TRR 142: TRR 142 - Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen","_id":"53"},{"name":"TRR 142 - C: TRR 142 - Project Area C","_id":"56"},{"_id":"174","name":"TRR 142 - C10: TRR 142 -  Erzeugung und Charakterisierung von Quantenlicht in nichtlinearen Systemen: Eine theoretische Analyse (C10*)"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"citation":{"apa":"Scharwald, D., Meier, T., &#38; Sharapova, P.

Finally we provide proof-of-principle results concerning the numerical calculation of invariant Ruelle distributions for 3-disc scattering systems."}],"date_created":"2022-05-04T12:27:46Z","external_id":{"arxiv":["2112.05791"]},"department":[{"_id":"10"},{"_id":"548"},{"_id":"623"},{"_id":"15"}],"type":"journal_article"},{"doi":"10.1002/qute.202300142","article_number":"2300142","language":[{"iso":"eng"}],"date_updated":"2025-09-12T11:16:12Z","publication_status":"published","intvolume":"         7","title":"On‐Demand Indistinguishable and Entangled Photons Using Tailored Cavity Designs","year":"2023","publication_identifier":{"issn":["2511-9044","2511-9044"]},"author":[{"first_name":"David","last_name":"Bauch","full_name":"Bauch, David"},{"full_name":"Siebert, Dustin","first_name":"Dustin","last_name":"Siebert"},{"id":"85353","full_name":"Jöns, Klaus D.","first_name":"Klaus D.","last_name":"Jöns"},{"id":"158","orcid":"0000-0001-7059-9862","first_name":"Jens","last_name":"Förstner","full_name":"Förstner, Jens"},{"id":"27271","last_name":"Schumacher","first_name":"Stefan","orcid":"0000-0003-4042-4951","full_name":"Schumacher, Stefan"}],"type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"642"},{"_id":"61"},{"_id":"230"},{"_id":"35"},{"_id":"34"},{"_id":"429"},{"_id":"27"},{"_id":"623"}],"date_created":"2025-09-12T11:11:56Z","abstract":[{"lang":"eng","text":"<jats:title>Abstract</jats:title><jats:p>The biexciton‐exciton emission cascade commonly used in quantum‐dot systems to generate polarization entanglement yields photons with intrinsically limited indistinguishability. In the present work, it focuses on the generation of pairs of photons with high degrees of polarization entanglement and simultaneously high indistinguishability. It achieves this goal by selectively reducing the biexciton lifetime with an optical resonator. It demonstrates that a suitably tailored circular Bragg reflector fulfills the requirements of sufficient selective Purcell enhancement of biexciton emission paired with spectrally broad photon extraction and twofold degenerate optical modes. The in‐depth theoretical study combines (i) the optimization of realistic photonic structures solving Maxwell's equations from which model parameters are extracted as input for (ii) microscopic simulations of quantum‐dot cavity excitation dynamics with full access to photon properties. It reports non‐trivial dependencies on system parameters and use the predictive power of the combined theoretical approach to determine the optimal range of Purcell enhancement that maximizes indistinguishability and entanglement to near unity values, here specifically for the telecom C‐band at 1550 nm.</jats:p>"}],"publication":"Advanced Quantum Technologies","issue":"1","user_id":"16199","volume":7,"_id":"61252","publisher":"Wiley","status":"public","project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"},{"_id":"53","name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"},{"name":"TRR 142 - Project Area B","_id":"55"},{"name":"TRR 142 - Project Area C","_id":"56"},{"_id":"167","name":"TRR 142; TP B06: Ultraschnelle kohärente opto-elektronische Kontrolle eines photonischen Quantensystems"},{"name":"TRR 142; TP C09: Ideale Erzeugung von Photonenpaaren für Verschränkungsaustausch bei Telekom Wellenlängen","_id":"173"},{"_id":"266","name":"PhoQC: Photonisches Quantencomputing"}],"citation":{"apa":"Bauch, D., Siebert, D., Jöns, K.

Observations, such as coherence times that exceed the nanosecond scale obtained by monitoring the temporal decay of quantum coherence in a polariton condensate, are discussed. Proof-of-concept experiments and numerical simulations that demonstrate the enhanced resourcefulness of the produced system states for modern quantum protocols are assessed.
