Up to thousands of specific cytidines are converted into uridines in plant chloroplasts and mitochondria whereas up to millions of adenosines are converted into inosines in animal nucleo-cytosolic RNAs. It is unknown whether these two different RNA editing machineries are mutually incompatible. RNA-binding pentatricopeptide repeat (PPR) proteins are the key factors of plant organelle cytidine-to-uridine RNA editing. The complete absence of PPR mediated editing of cytosolic RNAs might be due to a yet unknown barrier that prevents its activity in the cytosol. Here, we transferred two plant mitochondrial PPR-type editing factors into human cell lines to explore whether they could operate in the nucleo-cytosolic environment. PPR56 and PPR65 not only faithfully edited their native, co-transcribed targets but also different sets of off-targets in the human background transcriptome. More than 900 of such off-targets with editing efficiencies up to 91%, largely explained by known PPR-RNA binding properties, were identified for PPR56. Engineering two crucial amino acid positions in its PPR array led to predictable shifts in target recognition. We conclude that plant PPR editing factors can operate in the entirely different genetic environment of the human nucleo-cytosol and can be intentionally re-engineered towards new targets.</jats:p>"}],"date_created":"2024-01-04T08:23:01Z","keyword":["Genetics"],"type":"journal_article","department":[{"_id":"27"}]},{"type":"preprint","date_created":"2024-01-05T12:51:30Z","external_id":{"arxiv":["2211.00559"]},"project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"abstract":[{"text":"We study the influence of fringing magnetic fields on turbulent thermal\r\nconvection in a horizontally extended rectangular domain.

These applications require state-of-the-art engineering to reach optimized functionalities such as high directivity and radiation efficiency, low sidelobe levels, broadband and tunable capabilities, and compact design. In this work, we report on the numerical optimization of the directivity of optical traveling wave antennas made from low-loss dielectric materials using full-wave numerical simulations in conjunction with the particle swarm optimization algorithm. The antennas are composed of a reflector and a director deposited on a glass substrate, and an emitter placed in the feed gap between them serves as an internal source of excitation. In particular, we analyze antennas with rectangular- and horn-shaped directors made of either hafnium dioxide or silicon. The optimized antennas produce highly directional emissions due to the presence of two dominant guided TE modes in the director in addition to leaky modes. These guided modes dominate the far-field emission pattern and govern the direction of the main lobe emission, which predominately originates from the end facet of the director. Our work also provides a comprehensive analysis of the modes, radiation patterns, parametric influences, and bandwidths of the antennas, which highlights their robust nature.","lang":"eng"}]},{"abstract":[{"text":"We study a double-scattering coherent mechanism of negative polarization (NP) near opposition that is observed for powder-like surfaces.

Simulations with regular shapes and controlled geometric parameters show that the interference mechanism is sensitive to the geometry of the scattering system and can also result in no polarization or even strong enhancement of positive polarization at backscattering.","lang":"eng"}],"publication":"Optics Letters","issue":"1","keyword":["tet_topic_scattering"],"type":"journal_article","department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"file":[{"content_type":"application/pdf","file_id":"29076","file_size":3197213,"date_updated":"2021-12-21T13:53:47Z","embargo":"2022-12-21","relation":"main_file","creator":"fossie","access_level":"local","file_name":"2022-01 Alhaddad - Optics Letter - Double Scattering.pdf","date_created":"2021-12-21T13:53:47Z","embargo_to":"open_access"}],"date_created":"2021-12-21T13:49:29Z","date_updated":"2024-07-22T07:45:05Z","publication_status":"published","intvolume":"        47","title":"Numerical analysis of the coherent mechanism producing negative polarization at backscattering from systems of absorbing particles","year":"2022","author":[{"full_name":"Alhaddad, Samer","last_name":"Alhaddad","first_name":"Samer","id":"42456"},{"id":"26059","first_name":"Yevgen","last_name":"Grynko","full_name":"Grynko, Yevgen"},{"orcid":"0000-0001-7730-3489","first_name":"Henna","last_name":"Farheen","full_name":"Farheen, Henna","id":"53444"},{"full_name":"Förstner, Jens","orcid":"0000-0001-7059-9862","first_name":"Jens","last_name":"Förstner","id":"158"}],"publication_identifier":{"issn":["0146-9592","1539-4794"]},"doi":"10.1364/ol.444953","language":[{"iso":"eng"}],"project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"file_date_updated":"2021-12-21T13:53:47Z","citation":{"ieee":"S.

In this paper, we design and optimize three distinct broadband traveling-wave tantalum pentoxide antennas exhibiting highly directional characteristics. Our antennas contain a director and reflector deposited on a glass substrate, which are excited by a dipole emitter placed in the feed gap between the two elements. Full-wave simulations in conjunction with global optimization provide structures with an enhanced linear directivity as high as 119 radiating in the substrate. The high directivity is a result of the interplay between two dominant TE modes and the leaky modes present in the antenna director. Furthermore, these low-loss dielectric antennas exhibit a near-unity radiation efficiency at the operational wavelength of 780 nm and maintain a broad bandwidth. Our numerical results are in good agreement with experimental measurements from the optimized antennas fabricated using a two-step electron-beam lithography, revealing the highly directive nature of our structures. We envision that our antenna designs can be conveniently adapted to other dielectric materials and prove instrumental for inter-chip optical communications and other on-chip applications.","lang":"eng"}],"date_created":"2022-05-18T16:39:17Z","department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"type":"journal_article","keyword":["tet_topic_opticalantenna"],"author":[{"full_name":"Farheen, Henna","orcid":"0000-0001-7730-3489","last_name":"Farheen","first_name":"Henna","id":"53444"},{"first_name":"Lok-Yee","last_name":"Yan","full_name":"Yan, Lok-Yee"},{"first_name":"Viktor","last_name":"Quiring","full_name":"Quiring, Viktor"},{"orcid":"https://orcid.org/0000-0002-5693-3083","first_name":"Christof","last_name":"Eigner","full_name":"Eigner, Christof","id":"13244"},{"id":"30525","full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101","last_name":"Zentgraf","first_name":"Thomas"},{"full_name":"Linden, Stefan","first_name":"Stefan","last_name":"Linden"},{"full_name":"Förstner, Jens","orcid":"0000-0001-7059-9862","last_name":"Förstner","first_name":"Jens","id":"158"},{"id":"46371","last_name":"Myroshnychenko","first_name":"Viktor","full_name":"Myroshnychenko, Viktor"}],"publication_identifier":{"issn":["1094-4087"]},"title":"Broadband optical Ta2O5 antennas for directional emission of light","year":"2022","intvolume":"        30","date_updated":"2024-07-22T07:44:58Z","publication_status":"published","language":[{"iso":"eng"}],"doi":"10.1364/oe.455815"},{"volume":117,"user_id":"49265","_id":"34065","publisher":"Elsevier BV","status":"public","project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"citation":{"ama":"Kirchgässner W, Wallscheid O, Böcker J.

Cavities with low <jats:italic>Q</jats:italic>-factors are generally given less attention due to their high losses that quickly destroy quantum systems. However, bad cavities can be utilized for several applications, where lower <jats:italic>Q</jats:italic>-factors are required, e.g., to increase the spectral width of the cavity mode. In this work, we demonstrate that low-<jats:italic>Q</jats:italic> cavities can be beneficial for preparing specific electronic steady states when certain quantum states of light are applied. We investigate the interaction between quantum light with various statistics and matter represented by a Λ-type three-level system in lossy cavities, assuming that cavity losses are the dominant loss mechanism. We show that cavity losses lead to non-trivial electronic steady states that can be controlled by the loss rate and the initial statistics of the quantum fields. We discuss the mechanism of the formation of such steady states on the basis of the equations of motion and present both analytical expressions and numerical simulations for such steady states.</jats:p>"}],"publication":"New Journal of Physics","issue":"6"},{"publication":"Physical Review B","issue":"20","date_created":"2023-01-18T10:58:12Z","department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"623"},{"_id":"35"},{"_id":"429"}],"type":"journal_article","publication_identifier":{"issn":["2469-9950","2469-9969"]},"author":[{"full_name":"Grisard, S.","last_name":"Grisard","first_name":"S."},{"orcid":"0000-0002-3079-5428","first_name":"Hendrik","last_name":"Rose","full_name":"Rose, Hendrik","id":"55958"},{"full_name":"Trifonov, A.

Several different approaches to realize solid-state quantum emitters with high performance have been pursued and different concepts for energy tuning have been established. However, the properties of the emitted photons are always defined by the individual quantum emitter and can therefore not be controlled with full flexibility. Here we introduce an all-optical nonlinear method to tailor and control the single photon emission. We demonstrate a laser-controlled down-conversion process from an excited state of a semiconductor quantum three-level system. Based on this concept, we realize energy tuning and polarization control of the single photon emission with a control-laser field. Our results mark an important step towards tailored single photon emission from a photonic quantum system based on quantum optical principles.</jats:p>","lang":"eng"}],"language":[{"iso":"eng"}],"article_number":"1387","doi":"10.1038/s41467-022-28993-3","author":[{"full_name":"Jonas, B.","first_name":"B.","last_name":"Jonas"},{"id":"10904","first_name":"Dirk Florian","last_name":"Heinze","full_name":"Heinze, Dirk Florian"},{"full_name":"Schöll, E.","first_name":"E.","last_name":"Schöll"},{"full_name":"Kallert, P.","last_name":"Kallert","first_name":"P."},{"last_name":"Langer","first_name":"T.","full_name":"Langer, T."},{"full_name":"Krehs, S.","first_name":"S.","last_name":"Krehs"},{"first_name":"A.","last_name":"Widhalm","full_name":"Widhalm, A."},{"id":"85353","full_name":"Jöns, Klaus","first_name":"Klaus","last_name":"Jöns"},{"last_name":"Reuter","first_name":"Dirk","full_name":"Reuter, Dirk","id":"37763"},{"id":"27271","full_name":"Schumacher, Stefan","first_name":"Stefan","last_name":"Schumacher","orcid":"0000-0003-4042-4951"},{"id":"606","full_name":"Zrenner, Artur","last_name":"Zrenner","first_name":"Artur","orcid":"0000-0002-5190-0944"}],"publication_identifier":{"issn":["2041-1723"]},"year":"2022","title":"Nonlinear down-conversion in a single quantum dot","intvolume":"        13","date_updated":"2023-04-20T15:18:31Z","publication_status":"published"},{"date_created":"2023-01-26T15:45:42Z","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"290"},{"_id":"230"},{"_id":"429"},{"_id":"623"},{"_id":"35"}],"type":"journal_article","publication":"Physical Review B","issue":"4","language":[{"iso":"eng"}],"article_number":"045302","doi":"10.1103/physrevb.105.045302","author":[{"full_name":"Praschan, Tom","last_name":"Praschan","first_name":"Tom"},{"full_name":"Heinze, Dirk","last_name":"Heinze","first_name":"Dirk"},{"last_name":"Breddermann","first_name":"Dominik","full_name":"Breddermann, Dominik"},{"full_name":"Zrenner, Artur","orcid":"0000-0002-5190-0944","first_name":"Artur","last_name":"Zrenner","id":"606"},{"last_name":"Walther","first_name":"Andrea","full_name":"Walther, Andrea"},{"id":"27271","full_name":"Schumacher, Stefan","last_name":"Schumacher","orcid":"0000-0003-4042-4951","first_name":"Stefan"}],"publication_identifier":{"issn":["2469-9950","2469-9969"]},"year":"2022","title":"Pulse shaping for on-demand emission of single Raman photons from a quantum-dot biexciton","intvolume":"       105","date_updated":"2023-04-20T15:19:24Z","publication_status":"published","citation":{"ieee":"T.

In this work, the formation of (defect) bound polarons in lithium niobate is studied by ab initio molecular dynamics. The calculations show a broad scatter of polaron formation times. Rising temperature increases the share of trajectories with long formation times, which leads to an overall increase of the average formation time with temperature. However, even at elevated temperatures, the average formation time does not exceed the value of 100 femtoseconds, i.e., a value close to the time measured for free, i.e., self-trapped polarons. Analyzing individual trajectories, it is found that the time required for the structural relaxation of the polarons depends sensitively on the excitation of the lithium niobate high-frequency phonon modes and their phase relation.</jats:p>"}],"language":[{"iso":"eng"}],"doi":"10.1007/s00339-022-05577-y","title":"Bound polaron formation in lithium niobate from ab initio molecular dynamics","year":"2022","author":[{"id":"52309","last_name":"Krenz","first_name":"Marvin","full_name":"Krenz, Marvin"},{"id":"171","full_name":"Gerstmann, Uwe","first_name":"Uwe","orcid":"0000-0002-4476-223X","last_name":"Gerstmann"},{"id":"468","full_name":"Schmidt, Wolf Gero","orcid":"0000-0002-2717-5076","last_name":"Schmidt","first_name":"Wolf Gero"}],"publication_identifier":{"issn":["0947-8396","1432-0630"]},"date_updated":"2023-04-21T11:06:37Z","publication_status":"published","intvolume":"       128","citation":{"bibtex":"@article{Krenz_Gerstmann_Schmidt_2022, title={Bound polaron formation in lithium niobate from ab initio molecular dynamics}, volume={128}, DOI={<a href=\"https://doi.org/10.1007/s00339-022-05577-y\">10.1007/s00339-022-05577-y</a>}, journal={Applied Physics A}, publisher={Springer Science and Business Media LLC}, author={Krenz, Marvin and Gerstmann, Uwe and Schmidt, Wolf Gero}, year={2022}, pages={480} }","ama":"Krenz M, Gerstmann U, Schmidt WG.
