PVVBs are typically generated through the superposition of perfect vortex beams, which suffer from the limited number of topological charges (TCs). Furthermore, dynamic control of PVVBs is desirable and has not been reported. We propose and experimentally demonstrate hybrid grafted perfect vector vortex beams (GPVVBs) and their dynamic control. Hybrid GPVVBs are generated through the superposition of grafted perfect vortex beams with a multifunctional metasurface. The generated hybrid GPVVBs possess spatially variant rates of polarization change due to the involvement of more TCs. Each hybrid GPVVB includes different GPVVBs in the same beam, adding more design flexibility. Moreover, these beams are dynamically controlled with a rotating half waveplate. The generated dynamic GPVVBs may find applications in the fields where dynamic control is in high demand, including optical encryption, dense data communication, and multiple particle manipulation.","lang":"eng"}],"date_created":"2023-07-06T06:34:37Z","file":[{"creator":"zentgraf","date_created":"2023-07-06T06:40:28Z","file_name":"NatureCommun_Ahmed_2023.pdf","file_size":4341041,"access_level":"closed","relation":"main_file","date_updated":"2023-07-06T06:40:28Z","file_id":"45869","success":1,"content_type":"application/pdf"}],"department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"keyword":["General Physics and Astronomy","General Biochemistry","Genetics and Molecular Biology","General Chemistry","Multidisciplinary"],"type":"journal_article"},{"user_id":"63231","volume":31,"_id":"45850","publisher":"Optica Publishing Group","status":"public","citation":{"mla":"Babel, Silia, et al. “Demonstration of Hong-Ou-Mandel Interference in an LNOI Directional Coupler.” <i>Optics Express</i>, vol. 31, no. 14, 23140, Optica Publishing Group, 2023, doi:<a href=\"https://doi.org/10.1364/oe.484126\">10.1364/oe.484126</a>.","bibtex":"@article{Babel_Bollmers_Massaro_Luo_Stefszky_Pegoraro_Held_Herrmann_Eigner_Brecht_et al._2023, title={Demonstration of Hong-Ou-Mandel interference in an LNOI directional coupler}, volume={31}, DOI={<a href=\"https://doi.org/10.1364/oe.484126\">10.1364/oe.484126</a>}, number={1423140}, journal={Optics Express}, publisher={Optica Publishing Group}, author={Babel, Silia and Bollmers, Laura and Massaro, Marcello and Luo, Kai Hong and Stefszky, Michael and Pegoraro, Federico and Held, Philip and Herrmann, Harald and Eigner, Christof and Brecht, Benjamin and et al.}, year={2023} }","ama":"Babel S, Bollmers L, Massaro M, et al.

Here, we realise Hong-Ou-Mandel (HOM) interference between telecom photons from an engineered parametric down-conversion source in an LNOI directional coupler. The coupler has been designed and fabricated in house and provides close to perfect balanced beam splitting. We obtain a raw HOM visibility of (93.5 ± 0.7) %, limited mainly by the source performance and in good agreement with off-chip measurements.

It says that among all possible motions\nconnecting two points in a phase space, the system will exhibit those motions which extremise an action functional.\nMany qualitative features of dynamical systems, such as the presence of conservation laws and energy balance equa-\ntions, are related to the existence of an action functional. Incorporating variational structure into learning algorithms\nfor dynamical systems is, therefore, crucial in order to make sure that the learned model shares important features\nwith the exact physical system. In this paper we show how to incorporate variational principles into trajectory predic-\ntions of learned dynamical systems. The novelty of this work is that (1) our technique relies only on discrete position\ndata of observed trajectories. Velocities or conjugate momenta do not need to be observed or approximated and no\nprior knowledge about the form of the variational principle is assumed. Instead, they are recovered using backward\nerror analysis. (2) Moreover, our technique compensates discretisation errors when trajectories are computed from the\nlearned system. This is important when moderate to large step-sizes are used and high accuracy is required. For this,\nwe introduce and rigorously analyse the concept of inverse modified Lagrangians by developing an inverse version of\nvariational backward error analysis.

Many qualitative features of dynamical systems, such as the presence of conservation laws and energy balance equations, are related to the existence of an action functional. Incorporating variational structure into learning algorithms for dynamical systems is, therefore, crucial in order to make sure that the learned model shares important features with the exact physical system. In this paper we show how to incorporate variational principles into trajectory predictions of learned dynamical systems. The novelty of this work is that (1) our technique relies only on discrete position data of observed trajectories. Velocities or conjugate momenta do not need to be observed or approximated and no prior knowledge about the form of the variational principle is assumed. Instead, they are recovered using backward error analysis. (2) Moreover, our technique compensates discretisation errors when trajectories are computed from the learned system. This is important when moderate to large step-sizes are used and high accuracy is required. For this,\r\nwe introduce and rigorously analyse the concept of inverse modified Lagrangians by developing an inverse version of variational backward error analysis. (3) Finally, we introduce a method to perform system identification from position observations only, based on variational backward error analysis."}]},{"status":"public","volume":13,"user_id":"37763","_id":"44851","publisher":"AIP Publishing","citation":{"ieee":"D.

These alloys are subjected to marine environments with a high NaCl concentration, therefore, corrosion and catastrophic failure are anticipated. So, the surface dissolution of additively manufactured FeCo samples is investigated in a quasi-<jats:italic>in situ</jats:italic> manner, in particular, the pitting corrosion in 5.0 wt pct NaCl solution. The local dissolution of the same sample region is monitored after 24, 72, and 168 hours. Here, the formation of rectangular and circular pits of ultra-fine dimensions (less than 0.5 <jats:italic>µ</jats:italic>m) is observed with increasing immersion time. In addition, the formation of a corrosion-inhibiting surface layer is detected on the sample surface. Surface dissolution leads to a change in the surface structure, however, no change in grain shape or grain size is noticed. The surface topography after local dissolution is correlated to the grain orientation. Quasi-<jats:italic>in situ</jats:italic> analysis shows the preferential dissolution of high-angle grain boundaries (HAGBs) leading to a change in the fraction of HAGBs and low-angle grain boundaries fraction (LAGBs).

Two different approaches are physical modelling and data‐driven modelling, both of which have their respective advantages and disadvantages. By combining these two approaches, hybrid models can be created in which the respective disadvantages are mitigated, with discrepancy models being a particular subclass. Here, the basic system behaviour is described physically, that is, in the form of differential equations. Inaccuracies resulting from insufficient modelling or numerics lead to a discrepancy between the measurements and the model, which can be compensated by a data‐driven error correction term. Since discrepancy methods still require a large amount of measurement data, this paper investigates the extent to which a single discrepancy model can be trained for a physical model with additional parameter dependencies without the need for retraining. As an example, a damped electromagnetic oscillating circuit is used. The physical model is realised by a differential equation describing the electric current, considering only inductance and capacitance; dissipation due to resistance is neglected. This creates a discrepancy between measurement and model, which is corrected by a data‐driven model. In the experiments, the inductance and the capacity are varied. It is found that the same data‐driven model can only be used if additional parametric dependencies in the data‐driven term are considered as well."}]},{"type":"journal_article","keyword":["Atomic and Molecular Physics","and Optics"],"department":[{"_id":"15"},{"_id":"623"},{"_id":"230"},{"_id":"429"},{"_id":"642"}],"date_created":"2023-01-12T14:46:40Z","abstract":[{"text":"<jats:p>Superconducting nanowire single-photon detectors (SNSPDs) show near unity efficiency, low dark count rate, and short recovery time. Combining these characteristics with temporal control of SNSPDs broadens their applications as in active de-latching for higher dynamic range counting or temporal filtering for pump-probe spectroscopy or LiDAR. To that end, we demonstrate active gating of an SNSPD with a minimum off-to-on rise time of 2.4 ns and a total gate length of 5.0 ns. We show how the rise time depends on the inductance of the detector in combination with the control electronics. The gate window is demonstrated to be fully and freely, electrically tunable up to 500 ns at a repetition rate of 1.0 MHz, as well as ungated, free-running operation. Control electronics to generate the gating are mounted on the 2.3 K stage of a closed-cycle sorption cryostat, while the detector is operated on the cold stage at 0.8 K. We show that the efficiency and timing jitter of the detector is not altered during the on-time of the gating window. We exploit gated operation to demonstrate a method to increase in the photon counting dynamic range by a factor 11.2, as well as temporal filtering of a strong pump in an emulated pump-probe experiment.</jats:p>","lang":"eng"}],"publication":"Optics Express","issue":"1","doi":"10.1364/oe.472058","article_number":"610","language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2025-12-11T13:05:14Z","intvolume":"        31","year":"2023","title":"Nanosecond gating of superconducting nanowire single-photon detectors using cryogenic bias circuitry","publication_identifier":{"issn":["1094-4087"]},"author":[{"full_name":"Hummel, Thomas","orcid":"0000-0001-8627-2119","first_name":"Thomas","last_name":"Hummel","id":"83846"},{"full_name":"Widhalm, Alex","last_name":"Widhalm","first_name":"Alex"},{"first_name":"Jan Philipp","last_name":"Höpker","full_name":"Höpker, Jan Philipp","id":"33913"},{"full_name":"Jöns, Klaus","first_name":"Klaus","last_name":"Jöns","id":"85353"},{"last_name":"Chang","first_name":"Jin","full_name":"Chang, Jin"},{"full_name":"Fognini, Andreas","first_name":"Andreas","last_name":"Fognini"},{"first_name":"Stephan","last_name":"Steinhauer","full_name":"Steinhauer, Stephan"},{"last_name":"Zwiller","first_name":"Val","full_name":"Zwiller, Val"},{"first_name":"Artur","orcid":"0000-0002-5190-0944","last_name":"Zrenner","full_name":"Zrenner, Artur","id":"606"},{"full_name":"Bartley, Tim","last_name":"Bartley","first_name":"Tim","id":"49683"}],"citation":{"mla":"Hummel, Thomas, et al. “Nanosecond Gating of Superconducting Nanowire Single-Photon Detectors Using Cryogenic Bias Circuitry.” <i>Optics Express</i>, vol. 31, no. 1, 610, Optica Publishing Group, 2023, doi:<a href=\"https://doi.org/10.1364/oe.472058\">10.1364/oe.472058</a>.","bibtex":"@article{Hummel_Widhalm_Höpker_Jöns_Chang_Fognini_Steinhauer_Zwiller_Zrenner_Bartley_2023, title={Nanosecond gating of superconducting nanowire single-photon detectors using cryogenic bias circuitry}, volume={31}, DOI={<a href=\"https://doi.org/10.1364/oe.472058\">10.1364/oe.472058</a>}, number={1610}, journal={Optics Express}, publisher={Optica Publishing Group}, author={Hummel, Thomas and Widhalm, Alex and Höpker, Jan Philipp and Jöns, Klaus and Chang, Jin and Fognini, Andreas and Steinhauer, Stephan and Zwiller, Val and Zrenner, Artur and Bartley, Tim}, year={2023} }","ama":"Hummel T, Widhalm A, Höpker JP, et al.

(2) Known process parameters for low-porosity parts were used to fabricate tensile strength specimens. Half of the specimens were heat-treated, and all specimens were tested for mechanical properties in a quasi-static tensile test. In addition, the material hardness was determined. (3) It was found that, firstly, heat treatment resulted in a sharp increase in mechanical properties such as hardness, elastic modulus, yield strength and ultimate strength. In addition to the increase in these properties, the elongation at break also decreases significantly after heat treatment. The choice of process, on the other hand, does not give either process a clear advantage in terms of mechanical properties but shows that it is necessary to consider the essential mechanical properties for a desired application.</jats:p>"}],"issue":"2","publication":"Crystals","doi":"10.3390/cryst13020157","language":[{"iso":"eng"}],"article_number":"157","article_type":"original","intvolume":"        13","publication_status":"published","date_updated":"2025-03-18T12:45:57Z","publication_identifier":{"issn":["2073-4352"]},"author":[{"full_name":"Gnaase, Stefan","last_name":"Gnaase","first_name":"Stefan","id":"25730"},{"id":"77214","full_name":"Niggemeyer, Dennis","last_name":"Niggemeyer","first_name":"Dennis"},{"id":"90491","full_name":"Lehnert, Dennis","last_name":"Lehnert","first_name":"Dennis"},{"id":"93904","first_name":"Christian","last_name":"Bödger","full_name":"Bödger, Christian"},{"id":"553","last_name":"Tröster","first_name":"Thomas","full_name":"Tröster, Thomas"}],"year":"2023","title":"Comparative Study of the Influence of Heat Treatment and Additive Manufacturing Process (LMD &amp; L-PBF) on the Mechanical Properties of Specimens Manufactured from 1.2709"},{"citation":{"ieee":"A.

Heart rate variability (HRV) offers easily obtainable diagnostic approaches to SRC-associated dysautonomia, but studies investigating HRV during sleep, a crucial time for post-traumatic cerebral regeneration, are relatively sparse. The aim of this study was to assess nocturnal HRV in athletes during their return to sports (RTS) after SRC in their home environment using wireless wrist sensors (E4, Empatica, Milan, Italy) and to explore possible relations with clinical concussion-associated sleep symptoms. Eighteen SRC athletes wore a wrist sensor obtaining photoplethysmographic data at night during RTS as well as one night after full clinical recovery post RTS (&gt;3 weeks). Nocturnal heart rate and parasympathetic activity of HRV (RMSSD) were calculated and compared using the Mann–Whitney U Test to values of eighteen; matched by sex, age, sport, and expertise, control athletes underwent the identical protocol. During RTS, nocturnal RMSSD of SRC athletes (Mdn = 77.74 ms) showed a trend compared to controls (Mdn = 95.68 ms, p = 0.021, r = −0.382, p adjusted using false discovery rate = 0.126) and positively correlated to “drowsiness” (r = 0.523, p = 0.023, p adjusted = 0.046). Post RTS, no differences in RMSSD between groups were detected. The presented findings in nocturnal cardiac parasympathetic activity during nights of RTS in SRC athletes might be a result of concussion, although its relation to recovery still needs to be elucidated. Utilization of wireless sensors and wearable technologies in home-based settings offer a possibility to obtain helpful objective data in the management of SRC.</jats:p>","lang":"eng"}],"date_created":"2023-07-04T11:30:24Z","department":[{"_id":"35"},{"_id":"176"}],"type":"journal_article","keyword":["Electrical and Electronic Engineering","Biochemistry","Instrumentation","Atomic and Molecular Physics","and Optics","Analytical Chemistry"],"publication_identifier":{"issn":["1424-8220"]},"author":[{"full_name":"Delling, Anne Carina","first_name":"Anne Carina","last_name":"Delling"},{"id":"9583","full_name":"Jakobsmeyer, Rasmus","orcid":"0000-0002-9385-0834","last_name":"Jakobsmeyer","first_name":"Rasmus"},{"last_name":"Coenen","first_name":"Jessica","full_name":"Coenen, Jessica"},{"full_name":"Christiansen, Nele","first_name":"Nele","last_name":"Christiansen"},{"last_name":"Reinsberger","first_name":"Claus","full_name":"Reinsberger, Claus","id":"48978"}],"year":"2023","title":"Home-Based Measurements of Nocturnal Cardiac Parasympathetic Activity in Athletes during Return to Sport after Sport-Related Concussion","intvolume":"        23","date_updated":"2025-08-28T13:41:09Z","publication_status":"published","language":[{"iso":"eng"}],"article_number":"4190","doi":"10.3390/s23094190"},{"year":"2023","title":"Development of an adaptive coaxial concrete rheometer and rheological characterisation of fresh concrete","publication_identifier":{"issn":["1617-8106"]},"author":[{"last_name":"Josch","first_name":"Sebastian","full_name":"Josch, Sebastian"},{"full_name":"Jesinghausen, Steffen","first_name":"Steffen","last_name":"Jesinghausen"},{"full_name":"Schmid, Hans-Joachim","first_name":"Hans-Joachim","last_name":"Schmid"}],"publication_status":"published","date_updated":"2026-06-17T04:42:06Z","intvolume":"        33","language":[{"iso":"eng"}],"doi":"10.1515/arh-2022-0140","publication":"Applied Rheology","issue":"1","abstract":[{"lang":"eng","text":"<jats:title>Abstract</jats:title>\n               <jats:p>The accessibility to rheological parameters for concrete is becoming more and more relevant. This is mainly related to the constantly emerging challenges, such as not only the development of high-strength concretes is progressing very fast but also the simulation of the flow behaviour is of high importance. The main problem, however, is that the rheological characterisation of fresh concrete is not possible via commercial rheometers. The so-called concrete rheometers provide valuable relative values for comparing different concretes, but they cannot measure absolute values.

The comparison of the ACCR with a commercial rheometer showed very good agreement for selected test materials (Newtonian fluid, shear thinning fluid, suspension, and yield stress fluid), so that self-compacting concrete was subsequently measured. Since these measurements showed a very high reproducibility, the rheological properties of the fresh concrete could be determined with high accuracy. The common flow models (Bingham (B), Herschel–Bulkley, modified Bingham (MB) models) were also tested for their applicability, with the Bingham and the modified Bingham model proving to be the best suitable ones.</jats:p>"}],"date_created":"2023-03-16T19:06:11Z","keyword":["Condensed Matter Physics","General Materials Science"],"type":"journal_article","department":[{"_id":"150"}],"status":"public","_id":"43032","publisher":"Walter de Gruyter GmbH","user_id":"3959","volume":33,"citation":{"bibtex":"@article{Josch_Jesinghausen_Schmid_2023, title={Development of an adaptive coaxial concrete rheometer and rheological characterisation of fresh concrete}, volume={33}, DOI={<a href=\"https://doi.org/10.1515/arh-2022-0140\">10.1515/arh-2022-0140</a>}, number={1}, journal={Applied Rheology}, publisher={Walter de Gruyter GmbH}, author={Josch, Sebastian and Jesinghausen, Steffen and Schmid, Hans-Joachim}, year={2023} }","ama":"Josch S, Jesinghausen S, Schmid H-J.

Here, we observe strong chiroptical responses in the linear and nonlinear optical regime for chiral L-handed helicoid-III nanoparticles and quantify them by means of an asymmetric factor, the so-called g-factor. We calculate the linear optical g-factors for two distinct chiroptical resonances to −0.12 and –0.43 and the nonlinear optical g-factors to −1.45 and −1.63. The results demonstrate that the chirality of the helicoid-III nanoparticles is strongly enhanced in the nonlinear regime."}],"issue":"3","publication":"ACS Photonics","doi":"10.1021/acsphotonics.1c00882","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://pubs.acs.org/doi/full/10.1021/acsphotonics.1c00882","open_access":"1"}],"intvolume":"         9","article_type":"original","date_updated":"2022-03-21T07:48:27Z","publication_status":"published","author":[{"full_name":"Spreyer, Florian","last_name":"Spreyer","first_name":"Florian"},{"first_name":"Jungho","last_name":"Mun","full_name":"Mun, Jungho"},{"first_name":"Hyeohn","last_name":"Kim","full_name":"Kim, Hyeohn"},{"last_name":"Kim","first_name":"Ryeong Myeong","full_name":"Kim, Ryeong Myeong"},{"full_name":"Nam, Ki Tae","last_name":"Nam","first_name":"Ki Tae"},{"first_name":"Junsuk","last_name":"Rho","full_name":"Rho, Junsuk"},{"last_name":"Zentgraf","orcid":"0000-0002-8662-1101","first_name":"Thomas","full_name":"Zentgraf, Thomas","id":"30525"}],"publication_identifier":{"issn":["2330-4022","2330-4022"]},"year":"2022","title":"Second Harmonic Optical Circular Dichroism of Plasmonic Chiral Helicoid-III Nanoparticles","oa":"1","external_id":{"arxiv":["arXiv:2202.13594"]},"quality_controlled":"1","citation":{"short":"F.
