Im vorliegenden Beitrag wird auf die Befragung der ErzieherInnen fokussiert, die mittels halbstandardisierter Fragebögen durchgeführt wurde. Untersucht wurde, wie sich der sprachlich-kulturelle Hintergrund der Kinder für das Kommunikationsverhalten der ErzieherInnen mit den Kindern in pädagogischer Anschlusskommunikation und in Gesprächen mit den Eltern der Kinder auswirkt. Hier wurde auch eine intersektionale Perspektive eingenommen und parallel zur Herkunftskultur auch das biologische Geschlecht der Kinder in die Auswertung einbezogen. Es stellte sich heraus, dass die Kommunikation sowohl mit den Kindern als auch mit den Eltern in Abhängigkeit der Herkunftskultur der Kinder und auch ihres Geschlechtes erfolgt. Pädagogisch ist zu fragen, inwiefern es den pädagogischen Fachkräften gelingt, benachteiligende Ausgangslagen auch tatsächlich auszugleichen und Partizipation im Sinne von Inklusion zu ermöglichen. Ausgehend von diesen Ergebnissen wird in diesem Beitrag die Bedeutung und Relevanz der Überschneidungen und Interdependenzen von Ungleichheitsdimensionen für eine inklusionsorientierte Qualifikation pädagogischer Fachkräfte in institutionell-frühkindlichen Medienbildungskontexten diskutiert. Konkret richtet sich der Blick auf die sprachlich-kulturelle Ein- und Vielfalt in den frühkindlichen Einrichtungen sowie die Wahrnehmungen und Einschätzungen der pädagogischen Fachkräfte, die sie in Hinblick auf die Kooperationswilligkeit der Eltern, die Anschlusskommunikation mit den Kindern und schließlich die medialen Fähig- und Fertigkeiten der Kinder äußern.","lang":"ger"}],"date_created":"2023-04-18T12:30:09Z","status":"public","volume":2,"publication_status":"published","publication":"QfI - Qualifizierung für Inklusion Online-Zeitschrift zur Forschung über Aus-, Fort- und Weiterbildung pädagogischer Fachkräfte","quality_controlled":"1","author":[{"id":"82970","last_name":"Günesli","full_name":"Günesli, Habib","first_name":"Habib"}]},{"page":"196–205","citation":{"ieee":"G.

Our approach complements and extends recent results that were based on Chebyshev's integral inequality \\cite{BA19}. The method developed here correlates arbitrary phase-space functions at arbitrary points in phase space, including multimode scenarios and higher-order correlations. Furthermore, our approach provides necessary and sufficient nonclassicality criteria, applies to phase-space functions beyond s-parametrized ones, and is accessible in experiments. To demonstrate the power of our technique, the quantum characteristics of discrete- and continuous-variable, single- and multimode, as well as pure and mixed states are certified only employing second-order correlations and Husimi functions, which always resemble a classical probability distribution. Moreover, nonlinear generalizations of our approach are studied. Therefore, a versatile and broadly applicable framework is devised to uncover quantum properties in terms of matrices of phase-space distributions."}],"status":"public","date_created":"2021-10-15T16:10:46Z","publication_status":"published","publication_identifier":{"issn":["2521-327X"]},"author":[{"first_name":"Martin","full_name":"Bohmann, Martin","last_name":"Bohmann"},{"last_name":"Agudelo","first_name":"Elizabeth","full_name":"Agudelo, Elizabeth"},{"full_name":"Sperling, Jan","orcid":"0000-0002-5844-3205","first_name":"Jan","id":"75127","last_name":"Sperling"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"706"},{"_id":"35"}],"publication":"Quantum"},{"article_number":"065101","doi":"10.1088/1402-4896/ab833b","date_updated":"2023-04-20T15:12:37Z","_id":"26292","type":"journal_article","year":"2020","citation":{"ieee":"J.

A commonly used approach to describe theoretical properties includes a phenomenological single-mode equation that complements the equation for the nonlinear optical response (interband polarization) of the semiconductor. Here, we show how to replace the single-mode equation by a fully predictive transfer function method that, in contrast to the single-mode equation, accounts for propagation, retardation, and pulse-filtering effects of the incident light field traversing the distributed Bragg reflector (DBR) mirrors, without substantially increasing the numerical complexity of the solution. As examples, we use cavities containing GaAs quantum wells and transition-metal dichalcogenides (TMDs)."}],"user_id":"16199","language":[{"iso":"eng"}],"date_updated":"2023-04-20T15:42:52Z","doi":"10.1364/ao.392014","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"230"},{"_id":"35"}],"publication_identifier":{"issn":["1559-128X","2155-3165"]},"publication_status":"published","title":"Transfer function replacement of phenomenological single-mode equations in semiconductor microcavity modeling"},{"language":[{"iso":"eng"}],"doi":"10.1364/ol.405400","date_updated":"2023-04-20T15:42:33Z","publication_identifier":{"issn":["0146-9592","1539-4794"]},"publication_status":"published","project":[{"name":"TRR 142","_id":"53"},{"_id":"54","name":"TRR 142 - Project Area A"},{"_id":"61","name":"TRR 142 - Subproject A4"}],"department":[{"_id":"230"},{"_id":"429"},{"_id":"15"},{"_id":"170"},{"_id":"705"},{"_id":"297"},{"_id":"35"}],"title":"Chiral condensates in a polariton hexagonal ring.","external_id":{"pmid":["33057263"]},"page":"5700-5703","year":"2020","type":"journal_article","citation":{"bibtex":"@article{Ma_Kartashov_Kavokin_Schumacher_2020, title={Chiral condensates in a polariton hexagonal ring.}, volume={45}, DOI={10.1364/ol.405400}, number={20}, journal={Optics Letters}, author={Ma, Xuekai and Kartashov, YV and Kavokin, A and Schumacher, Stefan}, year={2020}, pages={5700–5703} }","mla":"Ma, Xuekai, et al. “Chiral Condensates in a Polariton Hexagonal Ring.” Optics Letters, vol. 45, no. 20, 2020, pp. 5700–03, doi:10.1364/ol.405400.","apa":"Ma, X., Kartashov, Y., Kavokin, A., & Schumacher, S.

In inhomogeneous ensembles a macroscopic optical polarization decays rapidly due to dephasing, which, however, is reversible in photon echoes carrying complete information about the coherent ensemble dynamics. Control of the echo emission time is mandatory for applications. Here, we propose a concept to reach this goal. In a two-pulse photon echo sequence, we apply an additional resonant control pulse with multiple of 2π area. Depending on its arrival time, the control slows down dephasing or rephasing of the exciton ensemble during its action. We demonstrate for self-assembled (In,Ga)As quantum dots that the photon echo emission time can be retarded or advanced by up to 5 ps relative to its nominal appearance time without control. This versatile protocol may be used to obtain significantly longer temporal shifts for suitably tailored control pulses."}],"date_created":"2020-12-16T14:30:57Z","status":"public","volume":3,"publication":"Communications Physics","author":[{"full_name":"Kosarev, Alexander N.","first_name":"Alexander N.","last_name":"Kosarev"},{"id":"55958","last_name":"Rose","orcid":"0000-0002-3079-5428","full_name":"Rose, Hendrik","first_name":"Hendrik"},{"full_name":"Poltavtsev, Sergey V.","first_name":"Sergey V.","last_name":"Poltavtsev"},{"id":"138","last_name":"Reichelt","full_name":"Reichelt, Matthias","first_name":"Matthias"},{"full_name":"Schneider, Christian","first_name":"Christian","last_name":"Schneider"},{"last_name":"Kamp","full_name":"Kamp, Martin","first_name":"Martin"},{"full_name":"Höfling, Sven","first_name":"Sven","last_name":"Höfling"},{"last_name":"Bayer","full_name":"Bayer, Manfred","first_name":"Manfred"},{"first_name":"Torsten","full_name":"Meier, Torsten","orcid":"0000-0001-8864-2072","last_name":"Meier","id":"344"},{"first_name":"Ilya A.","full_name":"Akimov, Ilya A.","last_name":"Akimov"}],"issue":"1","article_number":"228","intvolume":" 3","_id":"20773","year":"2020","citation":{"short":"A.N.

With their additional degree of freedom, the vorticity, they have been widely investigated in many physical systems and different materials for fundamental interest and for applications in data storage and information processing. Vortices have also been observed in non-equilibrium exciton-polariton condensates in planar semiconductor microcavities. There they appear spontaneously or can be created and pinned in space using ring-shaped optical excitation profiles. However, using the vortex state for information processing not only requires creation of a vortex but also efficient control over the vortex after its creation. Here we demonstrate a simple approach to control and switch a localized polariton vortex between opposite states. In our scheme, both the optical control of vorticity and its detection through the orbital angular momentum of the emitted light are implemented in a robust and practical manner.","lang":"eng"}],"volume":11,"status":"public","date_created":"2023-04-16T01:50:29Z","author":[{"id":"344","last_name":"Meier","orcid":"0000-0001-8864-2072","full_name":"Meier, Torsten","first_name":"Torsten"},{"first_name":"Xuekai","full_name":"Ma, Xuekai","last_name":"Ma"},{"full_name":"Berger, Bernd","first_name":"Bernd","last_name":"Berger"},{"last_name":"Aßmann","first_name":"Marc","full_name":"Aßmann, Marc"},{"last_name":"Driben","full_name":"Driben, Rodislav","first_name":"Rodislav"},{"first_name":"Christian","full_name":"Schneider, Christian","last_name":"Schneider"},{"last_name":"Höfling","first_name":"Sven","full_name":"Höfling, Sven"},{"first_name":"Stefan","full_name":"Schumacher, Stefan","orcid":"0000-0003-4042-4951","last_name":"Schumacher","id":"27271"}],"publisher":"Nature Publishing Group UK","publication":"Nature communications","doi":"10.1038/s41467-020-14702-5","oa":"1","date_updated":"2023-04-21T11:23:46Z","language":[{"iso":"eng"}],"title":"Realization of all-optical vortex switching in exciton-polariton condensates","publication_status":"published","department":[{"_id":"293"},{"_id":"35"},{"_id":"2"},{"_id":"170"},{"_id":"297"},{"_id":"230"}]},{"department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"429"},{"_id":"35"}],"editor":[{"full_name":"Betz, Markus","first_name":"Markus","last_name":"Betz"},{"last_name":"Elezzabi","full_name":"Elezzabi, Abdulhakem Y.","first_name":"Abdulhakem Y."}],"publication_status":"published","publication_identifier":{"isbn":["9781510633193","9781510633209"]},"project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"name":"TRR 142","_id":"53"},{"_id":"54","name":"TRR 142 - Project Area A"},{"_id":"64","name":"TRR 142 - Subproject A7"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"title":"k.p-based multiband simulations of non-degenerate two-photon absorption in bulk GaAs","series_title":"SPIE Proceedings","language":[{"iso":"eng"}],"date_updated":"2023-04-21T11:22:44Z","doi":"10.1117/12.2545924","author":[{"id":"66789","last_name":"Hannes","full_name":"Hannes, Wolf-Rüdiger","orcid":"https://orcid.org/0000-0003-1210-4838","first_name":"Wolf-Rüdiger"},{"last_name":"Meier","id":"344","first_name":"Torsten","full_name":"Meier, Torsten","orcid":"0000-0001-8864-2072"}],"publication":"Ultrafast Phenomena and Nanophotonics XXIV","volume":11278,"status":"public","date_created":"2020-12-16T14:23:16Z","user_id":"16199","year":"2020","type":"conference","citation":{"ama":"Hannes W-R, Meier T. k.p-based multiband simulations of non-degenerate two-photon absorption in bulk GaAs.
