We show that such a measurement enables one to infer directly the degree of global coherence of that beam, which is linked by a simple relation to the number of modes characterizing the entanglement between the two generated beams. We illustrate the proposed method by an example of photon pairs generated in a periodically poled potassium titanyl phosphate (KTP) crystal with a symmetric group velocity matching for various durations of the pump pulse, resulting in different numbers of modes.

Here, a simulation technique is described, that predicts the shifts of frequency and half bandwidth, Δfn and ΔΓn, of a quartz resonator operating on different overtone orders, n, induced by structured samples in contact with the resonator surface in liquid. The technique, abbreviated as FreqD‐LBM, solves the Stokes equation in the frequency domain. The solution provides the complex amplitude of the area‐averaged tangential stress at the resonator surface, from which Δfn and ΔΓn are derived. Because the dynamical variables are complex amplitudes, the viscosity can be complex, as well. The technique naturally covers viscoelasticity. Limitations are linked to the grid resolution and to problems at large viscosity. Validation steps include viscoelastic films, rough surfaces, an oscillating cylinder in a viscous medium, and a free‐floating sphere above the resonator. Application examples are soft adsorbed particles, stiff adsorbed particles, and a large, immobile spherical cap above the resonator, which allows to study the high‐frequency properties of the material in the gap. FreqDLBM runs on an office PC and does not require expert knowledge of numerical techniques. It is accessible to an experimentalist."}],"date_created":"2025-12-18T16:57:22Z","type":"journal_article","author":[{"last_name":"Johannsmann","first_name":"Diethelm","full_name":"Johannsmann, Diethelm"},{"full_name":"Häusner, Paul","last_name":"Häusner","first_name":"Paul"},{"full_name":"Langhoff, Arne","last_name":"Langhoff","first_name":"Arne"},{"full_name":"Leppin, Christian","last_name":"Leppin","first_name":"Christian","id":"117722"},{"first_name":"Ilya","last_name":"Reviakine","full_name":"Reviakine, Ilya"},{"full_name":"Vanoppen, Viktor","first_name":"Viktor","last_name":"Vanoppen"}],"publication_identifier":{"issn":["2513-0390","2513-0390"]},"title":"The Frequency‐Domain Lattice Boltzmann Method (FreqD‐LBM): A Versatile Tool to Predict the QCM Response Induced by Structured Samples","year":"2025","article_type":"original","intvolume":" 8","publication_status":"published","date_updated":"2025-12-18T17:46:34Z","language":[{"iso":"eng"}],"article_number":"2401373","doi":"10.1002/adts.202401373","citation":{"mla":"Johannsmann, Diethelm, et al. “The Frequency‐Domain Lattice Boltzmann Method (FreqD‐LBM): A Versatile Tool to Predict the QCM Response Induced by Structured Samples.” Advanced Theory and Simulations, vol. 8, no. 7, 2401373, Wiley, 2025, doi:10.1002/adts.202401373.","bibtex":"@article{Johannsmann_Häusner_Langhoff_Leppin_Reviakine_Vanoppen_2025, title={The Frequency‐Domain Lattice Boltzmann Method (FreqD‐LBM): A Versatile Tool to Predict the QCM Response Induced by Structured Samples}, volume={8}, DOI={10.1002/adts.202401373}, number={72401373}, journal={Advanced Theory and Simulations}, publisher={Wiley}, author={Johannsmann, Diethelm and Häusner, Paul and Langhoff, Arne and Leppin, Christian and Reviakine, Ilya and Vanoppen, Viktor}, year={2025} }","ama":"Johannsmann D, Häusner P, Langhoff A, Leppin C, Reviakine I, Vanoppen V.

At the same time, most studies of the SEI apply ex situ characterization methods, which may introduce artifacts or misinterpretations as they do not investigate the SEI in its unaltered state immersed in liquid battery electrolyte. Thus, in this work, we focus on using the non-destructive combination of electrochemical quartz crystal microbalance with dissipation monitoring (EQCM-D) and impedance spectroscopy (EIS) in the same electrochemical cell. EQCM-D can not only probe the solidified products of the SEI but also allows for the monitoring of viscoelastic layers and viscosity changes of the electrolyte at the interphase during the SEI formation. EIS complements those results by providing electrochemical properties of the formed interphase. Our results highlight substantial differences in the physical and electrochemical properties between the SEI formed on copper and on amorphous carbon and show how formation parameters and the additive vinylene carbonate (VC) influence their growth. The EQCM-D results show consistently that much thicker SEIs are formed on carbon substrates in comparison to copper substrates."}],"extern":"1","issue":"7","publication":"Batteries","type":"journal_article","date_created":"2025-12-18T16:56:12Z","status":"public","user_id":"117722","volume":11,"publisher":"MDPI AG","_id":"63222","quality_controlled":"1","citation":{"chicago":"Stich, Michael, Christian Leppin, Falk Thorsten Krauss, Jesus Eduardo Valdes Landa, Isabel Pantenburg, Bernhard Roling, and Andreas Bund. “Comparing the SEI Formation on Copper and Amorphous Carbon: A Study with Combined Operando Methods.” Batteries 11, no. 7 (2025). https://doi.org/10.3390/batteries11070273.","short":"M.

A similar conclusion was drawn from optical videos, where the plants were injured and the milky fluid was stretched (sometimes forming fibers) after the cut. Rapid solidification cannot be explained with physical drying because physical drying is transport-limited and therefore is inherently slow. It can, however, be explained with coagulation being triggered by a sudden decrease in hydrostatic pressure. A mechanism based on a pressure drop is corroborated by optical videos of both plants being injured under water. While the liquid exuded by E. characias keeps streaming away, the liquid exuded by C. glomerata quickly forms a plug even under water. Presumably, the pressure drop causes an influx of serum into the laticifers. The serum, in turn, triggers a transition from a liquid–liquid phase separated state (an LLPS state) of a resin and hardener to a single-phase state. QCM measurements, optical videos, and cryo-SEM images suggest that LLPS plays a role in the solidification of C. glomerata.","lang":"eng"}],"publication":"Plants","issue":"5","type":"journal_article","date_created":"2025-12-18T16:58:15Z"},{"publication_identifier":{"issn":["1525-7797","1526-4602"]},"author":[{"id":"117722","first_name":"Christian","last_name":"Leppin","full_name":"Leppin, Christian"},{"first_name":"Agata","last_name":"Pomorska","full_name":"Pomorska, Agata"},{"last_name":"Morga","first_name":"Maria","full_name":"Morga, Maria"},{"first_name":"Pawel","last_name":"Pomastowski","full_name":"Pomastowski, Pawel"},{"full_name":"Fijałkowski, Piotr","first_name":"Piotr","last_name":"Fijałkowski"},{"full_name":"Michna, Aneta","first_name":"Aneta","last_name":"Michna"},{"first_name":"Diethelm","last_name":"Johannsmann","full_name":"Johannsmann, Diethelm"}],"title":"Swelling Degree of Polyelectrolyte Layers Determined by an Electrochemical Quartz Crystal Microbalance","year":"2025","article_type":"original","intvolume":" 26","publication_status":"published","date_updated":"2025-12-18T17:44:44Z","language":[{"iso":"eng"}],"doi":"10.1021/acs.biomac.4c01205","publication":"Biomacromolecules","issue":"2","extern":"1","abstract":[{"text":"Various polycations and polyanions were sequentially adsorbed onto the gold electrode of a quartz crystal microbalance with dissipation monitoring. The study focused on determining the adsorption kinetics, viscoelastic properties, and electroresponsivity of polyelectrolyte layers. For the first time, it was demonstrated that the structure (compact or expanded) of the layers can be determined by electroresponsivity. Viscoelastic modeling alone did not provide a conclusive answer as to whether the layers were compact or expanded. The study was further enriched by streaming potential and contact angle measurements, where polyelectrolyte multilayers were formed on mica. It was found that successive adsorption of layers led to periodic inversion of the zeta potential. Systematic differences were observed between the different top layers, which were explained by intermixing between layers. The presence or absence of interpenetration, as determined by the measurements of streaming potential and contact angles, correlated well with electroresponsivity.","lang":"eng"}],"date_created":"2025-12-18T16:59:12Z","type":"journal_article","status":"public","publisher":"American Chemical Society (ACS)","_id":"63225","page":"914-928","volume":26,"user_id":"117722","citation":{"mla":"Leppin, Christian, et al. “Swelling Degree of Polyelectrolyte Layers Determined by an Electrochemical Quartz Crystal Microbalance.” Biomacromolecules, vol. 26, no. 2, American Chemical Society (ACS), 2025, pp. 914–28, doi:10.1021/acs.biomac.4c01205.","bibtex":"@article{Leppin_Pomorska_Morga_Pomastowski_Fijałkowski_Michna_Johannsmann_2025, title={Swelling Degree of Polyelectrolyte Layers Determined by an Electrochemical Quartz Crystal Microbalance}, volume={26}, DOI={10.1021/acs.biomac.4c01205}, number={2}, journal={Biomacromolecules}, publisher={American Chemical Society (ACS)}, author={Leppin, Christian and Pomorska, Agata and Morga, Maria and Pomastowski, Pawel and Fijałkowski, Piotr and Michna, Aneta and Johannsmann, Diethelm}, year={2025}, pages={914–928} }","ama":"Leppin C, Pomorska A, Morga M, et al.

In this paper, we study linear representations of groups that intertwine with a permutation representation. Recently, D'Alconzo and Di Scala investigated how small the matrices in such a linear representation can be. The minimal dimension of such a representation is the \\emph{linear dimension of the group action} and this has applications in cryptography and cryptosystems.\r\n\r\nWe develop the idea of linear dimension from an algebraic point of view by using the theory of permutation modules. We give structural results about representations of minimal dimension and investigate the implications of faithfulness, transitivity and primitivity on the linear dimension. Furthermore, we compute the linear dimension of several classes of finite primitive permutation groups. We also study wreath products, allowing us to determine the linear dimension of imprimitive group actions. Finally, we give the linear dimension of almost simple finite $2$-transitive groups, some of which may be used for further applications in cryptography. Our results also open up many new questions about linear representations of group actions."}],"language":[{"iso":"eng"}],"_id":"63384","user_id":"91965","title":"Linear dimension of group actions","status":"public","year":"2025","author":[{"full_name":"Devillers, Alice","last_name":"Devillers","first_name":"Alice"},{"full_name":"Giudici, Michael","first_name":"Michael","last_name":"Giudici"},{"last_name":"Hawtin","first_name":"Daniel R.","full_name":"Hawtin, Daniel R."},{"full_name":"Klawuhn, Lukas-André Dominik","orcid":"0009-0009-7736-4885","first_name":"Lukas-André Dominik","last_name":"Klawuhn","id":"91965"},{"full_name":"Morgan, Luke","last_name":"Morgan","first_name":"Luke"}],"date_updated":"2025-12-19T11:23:41Z"},{"_id":"62906","publisher":"Verlag Barbara Budrich GmbH","page":"97 - 119","volume":5,"user_id":"21765","status":"public","citation":{"chicago":"Riedl, Lars, and Heiko Meier. “Protest gegen Kommerzialisierung im Fußball: Theoretische Überlegungen zu Entstehung, Strukturen und Nutzen.” FuG – Zeitschrift für Fußball und Gesellschaft 5, no. 2–2023 (2025): 97–119. https://doi.org/10.3224/fug.v5i2.02.","short":"L.

Gezeigt wird, dass Zuschauerproteste bereits umfassend beforscht sind, bislang allerdings keine theoretische Einordung zu ihrer Entwicklung vorgelegt wurde. Entsprechend liegt das Ziel des Beitrags darin, unter Rückgriff auf systemtheoretische Überlegungen, insbesondere auch zur Funktion des Publikums für den Fußball, und typologische Unterscheidungen, angereichert durch kulturanthropologische Betrachtungen, theoretische Erklärungen für die Ursprünge und Bedeutung von Zuschauerprotesten zu liefern. Im Anschluss hieran wird betrachtet, wie sich Zuschauerproteste in theoretische Konzepte zu Protestbewegungen einordnen lassen, um abschließend deren Nutzen für die Fußballclubs und -verbände zu bestimmen."}]}]
