The cluster adsorption is found to be dominated by van der Waals forces. The electronic structure and in particular the excitation energies of the bare clusters and the TiO2/graphene composites are found to vary largely in dependence on the size of the respective constituents. This holds in particular for the energy and the spatial localization of the highest occupied and lowest unoccupied molecular orbitals. In addition to a substantial gap narrowing, a pronounced separation of photoexcited electrons and holes is predicted in some instances. This is expected to prolong the lifetime of photoexcited carriers. Altogether, TiO2/graphene composites are predicted to be promising photocatalysts with improved electronic and photocatalytic properties compared to bulk TiO2.","lang":"eng"}],"article_type":"original","language":[{"iso":"eng"}],"doi":"10.1002/jcc.26363","oa":"1","date_updated":"2023-04-21T09:47:30Z","publication_status":"published","publication_identifier":{"issn":["0192-8651","1096-987X"]},"project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"230"},{"_id":"35"}],"title":"Photocatalytic properties of graphene‐supported titania clusters from density‐functional theory","related_material":{"link":[{"url":"https://onlinelibrary.wiley.com/action/downloadSupplement?doi=10.1002%2Fjcc.26363&file=jcc26363-sup-0002-Supinfo.pdf","relation":"supplementary_material"}]}},{"language":[{"iso":"eng"}],"date_updated":"2023-04-21T11:22:13Z","doi":"10.1038/s42005-020-00491-2","department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"623"},{"_id":"230"},{"_id":"35"}],"project":[{"_id":"53","name":"TRR 142"},{"_id":"54","name":"TRR 142 - Project Area A"},{"name":"TRR 142 - Subproject A2","_id":"59"}],"publication_identifier":{"issn":["2399-3650"]},"publication_status":"published","title":"Accurate photon echo timing by optical freezing of exciton dephasing and rephasing in quantum dots","type":"journal_article","citation":{"ama":"Kosarev AN, Rose H, Poltavtsev SV, et al.

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."}],"user_id":"16199"},{"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"}],"issue":"1","_id":"43747","intvolume":" 11","page":"897","year":"2020","citation":{"ieee":"T.

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,"date_created":"2023-04-16T01:50:29Z","status":"public","publication":"Nature communications","author":[{"last_name":"Meier","id":"344","first_name":"Torsten","full_name":"Meier, Torsten","orcid":"0000-0001-8864-2072"},{"last_name":"Ma","full_name":"Ma, Xuekai","first_name":"Xuekai"},{"full_name":"Berger, Bernd","first_name":"Bernd","last_name":"Berger"},{"last_name":"Aßmann","first_name":"Marc","full_name":"Aßmann, Marc"},{"full_name":"Driben, Rodislav","first_name":"Rodislav","last_name":"Driben"},{"full_name":"Schneider, Christian","first_name":"Christian","last_name":"Schneider"},{"last_name":"Höfling","full_name":"Höfling, Sven","first_name":"Sven"},{"last_name":"Schumacher","id":"27271","first_name":"Stefan","orcid":"0000-0003-4042-4951","full_name":"Schumacher, Stefan"}],"publisher":"Nature Publishing Group UK"},{"title":"k.p-based multiband simulations of non-degenerate two-photon absorption in bulk GaAs","department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"429"},{"_id":"35"}],"publication_status":"published","publication_identifier":{"isbn":["9781510633193","9781510633209"]},"editor":[{"last_name":"Betz","first_name":"Markus","full_name":"Betz, Markus"},{"first_name":"Abdulhakem Y.","full_name":"Elezzabi, Abdulhakem Y.","last_name":"Elezzabi"}],"project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"},{"_id":"53","name":"TRR 142"},{"name":"TRR 142 - Project Area A","_id":"54"},{"name":"TRR 142 - Subproject A7","_id":"64"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"date_updated":"2023-04-21T11:22:44Z","doi":"10.1117/12.2545924","series_title":"SPIE Proceedings","language":[{"iso":"eng"}],"user_id":"16199","publication":"Ultrafast Phenomena and Nanophotonics XXIV","author":[{"id":"66789","last_name":"Hannes","orcid":"https://orcid.org/0000-0003-1210-4838","full_name":"Hannes, Wolf-Rüdiger","first_name":"Wolf-Rüdiger"},{"first_name":"Torsten","full_name":"Meier, Torsten","orcid":"0000-0001-8864-2072","last_name":"Meier","id":"344"}],"volume":11278,"date_created":"2020-12-16T14:23:16Z","status":"public","intvolume":" 11278","_id":"20770","page":"112780S","type":"conference","citation":{"bibtex":"@inproceedings{Hannes_Meier_2020, series={SPIE Proceedings}, title={k.p-based multiband simulations of non-degenerate two-photon absorption in bulk GaAs}, volume={11278}, DOI={10.1117/12.2545924}, booktitle={Ultrafast Phenomena and Nanophotonics XXIV}, author={Hannes, Wolf-Rüdiger and Meier, Torsten}, editor={Betz, Markus and Elezzabi, Abdulhakem Y.}, year={2020}, pages={112780S}, collection={SPIE Proceedings} }","mla":"Hannes, Wolf-Rüdiger, and Torsten Meier. “K.p-Based Multiband Simulations of Non-Degenerate Two-Photon Absorption in Bulk GaAs.” Ultrafast Phenomena and Nanophotonics XXIV, edited by Markus Betz and Abdulhakem Y.
