High resolution X‐ray diffraction is performed to determine the lattice constant, using an Anton–Paar DHS1100 stage to vary the sample temperature from 25°C to 900°C, calibrated against the underlying single‐crystalline silicon substrate. A linear increase in\r\n a\r\n exp\r\n \ with rising temperature is observed. The thermal expansion behaviour is modelled using Debye´s phonon dispersion. The fitted lattice parameters are used to calculate the thermal expansion coefficient (TEC). At room temperature the TEC is determined to be\r\n α\r\n \ Debye \r\n ≈ 5.25 × 10\r\n −6\r\n  K\r\n \ −1\r\n . We further compare the TEC of the cubic GaN epilayer to that of free‐standing hexagonal GaN using the crystallographic relationship of , demonstrating good agreement between both phases. Using literature values for the elastic constants of cubic GaN, the corresponding elastic moduli and Debye temperature Θ\r\n D\r\n \ are calculated. An average value of Θ\r\n D\r\n \ of ≈905 ± 25 K is obtained, which is very close to our experimental results. Moreover, tensile strain is found to be present in our sample at room temperature, leading to an increase in the TEC. The impact of strain on the thermal properties of cubic GaN is discussed.\r\n " article_number: e202500477 article_type: original author: - first_name: Donat Josef full_name: As, Donat Josef id: '14' last_name: As orcid: 0000-0003-1121-3565 - first_name: Falco full_name: Meier, Falco last_name: Meier - first_name: Pascal full_name: Mahler, Pascal last_name: Mahler - first_name: Cedrik full_name: Meier, Cedrik id: '20798' last_name: Meier orcid: https://orcid.org/0000-0002-3787-3572 citation: ama: As DJ, Meier F, Mahler P, Meier C.

To this end, we consider different programs based on the restriction of the evolution to the set of separable (i.e., non-entangled) states, together with the discretization of the space of variables for numerical computations. As a first approach, we apply linear splitting methods to the restricted, continuous equations of motion derived from variational principles. We utilize an exchange interaction Hamiltonian to confirm that the numerical and analytical solutions coincide in the limit of small time steps. The application to different Hamiltonians shows the wide applicability of the method to detect dynamical entanglement. To avoid the derivation of analytical solutions for complex dynamics, we consider variational, numerical integration schemes, introducing a variational discretization for Lagrangians linear in velocities. Here, we examine and compare two approaches: one in which the system is discretized before the restriction is applied, and another in which the restriction precedes the discretization. We find that the ‘first-discretize-then-restrict’ method becomes numerically unstable, already for the example of an exchange-interaction Hamiltonian, which can be an important consideration for the numerical analysis of constrained quantum dynamics. Thereby, broadly applicable numerical tools, including their limitations, for studying entanglement over time are established for assessing the entangling power of processes that are used in quantum information theory." article_number: '225303' author: - first_name: Christian full_name: Offen, Christian last_name: Offen - first_name: Boris Edgar full_name: Wembe Moafo, Boris Edgar id: '95394' last_name: Wembe Moafo orcid: 0000-0002-6085-8071 - first_name: Laura full_name: Ares, Laura last_name: Ares - first_name: Jan full_name: Sperling, Jan id: '75127' last_name: Sperling orcid: 0000-0002-5844-3205 - first_name: Sina full_name: Ober-Blöbaum, Sina id: '16494' last_name: Ober-Blöbaum citation: ama: 'Offen C, Wembe Moafo BE, Ares L, Sperling J, Ober-Blöbaum S.

Recently, it has been experimentally demonstrated that photonic platforms based on Gaussian boson sampling (GBS) are capable of performing these simulations. However, whether an actual GBS approach is required depends on the molecule under investigation. To develop a better understanding on the requirements for simulating vibronic spectra, we explore connections between theoretical approximations in physical chemistry and their photonic counterparts. Mapping these approximations into photonics, we show that for certain molecules the GBS approach is unnecessary. We place special emphasis on the linear coupling approximation, which in photonics corresponds to sampling from multiple coherent states. By implementing this approach in experiments, we demonstrate improved similarities over previously reported GBS results for formic acid and identify the particular attributes that a molecule must exhibit for this, and other approximations, to be valid. These results highlight the importance in forming deeper connections between traditional methods and photonic approaches. article_number: '89' article_type: original author: - first_name: Jan-Lucas full_name: Eickmann, Jan-Lucas id: '73665' last_name: Eickmann orcid: 0009-0008-6524-7684 - first_name: Kai-Hong full_name: Luo, Kai-Hong id: '36389' last_name: Luo orcid: 0000-0003-1008-4976 - first_name: Mikhail full_name: Roiz, Mikhail id: '114114' last_name: Roiz - first_name: Jonas full_name: Lammers, Jonas last_name: Lammers - first_name: Simone full_name: Atzeni, Simone id: '98338' last_name: Atzeni - first_name: Cheeranjiv full_name: Pandey, Cheeranjiv last_name: Pandey - first_name: Florian full_name: Lütkewitte, Florian last_name: Lütkewitte - first_name: Reza G. full_name: Shirazi, Reza G. last_name: Shirazi - first_name: Fabian full_name: Schlue, Fabian id: '63579' last_name: Schlue - first_name: Benjamin full_name: Brecht, Benjamin id: '27150' last_name: Brecht orcid: '0000-0003-4140-0556 ' - first_name: Vladimir V. full_name: Rybkin, Vladimir V. last_name: Rybkin - first_name: Michael full_name: Stefszky, Michael id: '42777' last_name: Stefszky - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn citation: ama: 'Eickmann J-L, Luo K-H, Roiz M, et al.

We introduce a paradigm shift using a many‐body plasmonic architecture inspired by statistical mechanics. By moving toward the continuum limit, local geometric variations are statistically averaged out, effectively decoupling optical performance from microscopic disorder. We implement this concept via a lithography‐ and etching‐free, multi‐step dewetting strategy, creating wafer‐scale nanoclusters. This process strategically forms a robust many‐body system by introducing numerous small satellite nanoparticles between larger particles. Crucially, this design achieves a high collective enhancement that surpasses even optimized few‐body systems, despite having larger individual gaps. Under optimized conditions, these substrates exhibit a surface‐enhanced Raman scattering enhancement factor approaching 4 × 10^8 with unprecedented reproducibility (RSD of ∼10%). This scalable, low‐cost concept establishes a practical route toward reproducible wafer‐scale nanophotonic platforms for sensing, spectroscopy, and quantum technologies.' article_number: e71610 article_type: original author: - first_name: Minjun full_name: Kim, Minjun last_name: Kim - first_name: Vasanthan full_name: Devaraj, Vasanthan id: '103814' last_name: Devaraj - first_name: Hyeon‐Seok full_name: Seo, Hyeon‐Seok last_name: Seo - first_name: Seong‐Jae full_name: Eom, Seong‐Jae last_name: Eom - first_name: Jeong‐Su full_name: Lee, Jeong‐Su last_name: Lee - first_name: Donghan full_name: Lee, Donghan last_name: Lee - first_name: Min Yong full_name: Jeon, Min Yong last_name: Jeon - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 - first_name: Jong‐Min full_name: Lee, Jong‐Min last_name: Lee citation: ama: Kim M, Devaraj V, Seo H, et al.

Here, we demonstrate a hybrid nonlinear optoelectronic device that enhances the detection efficiency of a (001)-oriented GaAs PIN photodiode under telecommunication-wavelength illumination, where absorption is intrinsically limited to two-photon absorption (2PA). Our approach relies on the integration of a transferred, nanopatterned 385 nm-thick (111)-oriented GaAs nanofilm acting as an on-chip nonlinear frequency-conversion layer. Elliptical GaAs nanoresonators are employed to enhance second-harmonic generation (SHG) resonantly, converting incident 1550 nm radiation into above-bandgap photons efficiently absorbed by the underlying diode. Spatially resolved current–voltage measurements reveal a pronounced enhancement of the detector response in regions covered by the nanoantennas. The device exhibits a low dark current, while the metasurface-covered regions show the largest current response under 1560 nm excitation compared to the bare GaAs(100) diode and the unstructured GaAs(111) film. These results establish a direct functional link between dielectric metasurface–based nonlinear frequency conversion and electrical photodetection, providing a viable route toward integrated sub-bandgap detection schemes. article_number: '30335' article_type: original author: - first_name: Vladimir full_name: Spedt, Vladimir last_name: Spedt - first_name: Falco full_name: Meier, Falco last_name: Meier - first_name: René full_name: Geromel, René last_name: Geromel - first_name: Pascal full_name: Mahler, Pascal last_name: Mahler - first_name: Tobias full_name: Henksmeier, Tobias id: '42539' last_name: Henksmeier - first_name: Dirk full_name: Reuter, Dirk id: '37763' last_name: Reuter - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 - first_name: Cedrik full_name: Meier, Cedrik id: '20798' last_name: Meier orcid: https://orcid.org/0000-0002-3787-3572 citation: ama: Spedt V, Meier F, Geromel R, et al.

Dabei wird der Prozess der parametrischen Fluoreszenz (PDC) mithilfe von Integro-Differentialgleichungen modelliert, welche die räumliche Entwicklung der Ebene-Wellen-Operatoren beschreiben. Es wurde gezeigt, dass Supersensitivität für die Phasenempfindlichkeit dieser Interferometer erreicht werden kann, sofern die Beugung der PDC Strahlung kompensiert wird. Weiterhin führt eine Erhöhung der parametrische Verstärkung und eine Reduktion der Schmidt-Zahl zu einer Verbesserung der Phasenempfindlichkeit und einer Verkleinerung des Phasenbereiches, über den die Supersensitivität erreicht werden kann. Basierend auf der Struktur der Schmidt-Moden von SU(1,1) Interferometern wurde ein numerisches Aufbereitungsverfahren konstruiert, welches die Messung der Stärke des Squeezing und Anti-Squeezing des Zustandes ermöglicht, der durch den ersten Kristall des Interferometers erzeugt wird. Das Verfahren wurde experimentell von Kooperationspartnern angewandt, wobei eine gute Übereinstimmung mit der Theorie festgestellt wurde. Zuletzt wurden SU(1,1) Interferometer mit Laguerre-Gauß-Moden als Pump-Strahlung für die Messung von Winkelverschiebungen untersucht. Es zeigte sich, dass sich die quantenmechanisch bedingte Messunsicherheit verbessert, wenn die parametrische Verstärkung oder die Indizes der Pump-Mode erhöht werden. Das generelle Verhalten gleicht dem der Phasensensitivität. - lang: eng text: In this thesis, several aspects of high-gain multimode SU(1,1) interferometers are theoretically investigated, with the focus being on metrological applications. The parametric down-conversion (PDC) process utilized in these interferometers is theoretically described via integro-differential equations describing spatial evolution of the plane-wave operators. It is shown that for the phase sensitivity of these interferometers, supersensitivity can be reached provided that proper diffraction compensation is applied. The phase sensitivity improves if the gain is increased or if the number of effective modes is decreased. This comes at the cost of the phase-region width over which supersensitivity can be reached. Based on the Schmidt mode structure of SU(1,1) interferometers, a processing method is constructed which allows for the experimental retrieval of the levels of squeezing and anti-squeezing of the multimode state generated by the first PDC section of an SU(1,1) interferometer. It is then applied experimentally by collaborators and is found to be in good agreement with the theoretical predictions. Finally, SU(1,1) interferometers pumped with Laguerre-Gaussian beams are analyzed in the context of angular displacement measurements. As either the gain, the OAM index or the radial index of the pump are increased, the measurement uncertainty is decreased, ultimately allowing for supersensitive measurements. Generally, the behavior is the same as for the phase sensitivity. author: - first_name: Dennis full_name: Scharwald, Dennis id: '55907' last_name: Scharwald orcid: 0009-0007-5654-5412 citation: ama: Scharwald D.

These needs are—according to Ainscow’s (2007) inclusive turn—not primarily ‘special educational needs’, but diverse needs of all learners. For the rather segregated German educational system, this endeavour applies especially to primary education, where needs are still developing and pupils are not yet assigned to different types of schooling according to their needs and abilities.\r\n\r\nDespite a substantial amount of research on pupils’ basic psychological needs for autonomy, competence and social relatedness (Ryan et al., 2022), strategies that technology education teachers apply in this regard are not yet well understood. Besides interventional studies on technology education, indicating effectiveness of self‑directed and action‑oriented teaching and learning, there is a dearth of research on how teachers address different needs as a routine.\r\n\r\nThe purpose of the presented study is therefore to investigate and systematize actions and strategies teachers apply, and to specify how pupils' needs are considered when teaching technology education on a given topic.\r\n\r\nThe overall study used a mixed-methods approach to the question how pupils’ needs are characterized by themselves and by their teachers, and how they were taken into account in a lesson adapted and delivered by the teachers. In the sub-study presented here, participating primary school teachers were interviewed about their consideration of pupils’ needs whilst planning and conducting a technology education unit on the functionality of robots.\r\n\r\nThe results gained from qualitative content analysis of the interviews indicate that although the anticipation of different needs is considered challenging, teachers possess a substantiate amount of practices and strategies to take them into account.\r\n\r\nThe paper systematizes the practices teachers described in structured interviews within strategies and discusses the contribution of taking basic needs into account for inclusive technology education." alternative_title: - On Teachers’ Practices and Strategies to Teach Technology Inclusively at Primary Level author: - first_name: Franz full_name: Schröer, Franz last_name: Schröer - first_name: Claudia full_name: Tenberge, Claudia last_name: Tenberge citation: ama: 'Schröer F, Tenberge C. “They Really Need to Handle, Inspect, and Experience Things.” In: Linköping Electronic Conference Proceedings.

In fact, its operation, combined with single qubit rotations allows to realise any quantum circuit. Several strategies have been adopted in order to build quantum gates. Among them, photonics offers the dual advantage of excellent isolation from the environment and ease of manipulation at the single qubit level. Here we adopt a scalable time-multiplexed approach in order to build a fully reconfigurable architecture capable of implementing a post-selected C-NOT gate with a fidelity of (93.8 ± 1.4)%.

Here, we present a systematic optical investigation of large‐scale 3D AuNP assemblies fabricated via meniscus‐guided assembly, focusing on the reproducibility, spatial uniformity, and mode evolution of their plasmonic responses. Spatially‐resolved dark‐field scattering measurements reveal that high‐aspect‐ratio AuNP pillars exhibit uniform scattering spectra along their height and across different pillars, despite variations in geometry and structure. Electromagnetic simulations suggest that this robustness arises from a collective many‐particle plasmonic response that remains optically active despite structural perturbations. The corresponding near‐field and surface‐charge distributions remain spatially distributed under representative structural perturbations, consistent with volumetric averaging across the three‐dimensional assembly. Building on this robust platform, we introduce compositional modulation through a core–satellite architecture by incorporating smaller AuNPs. This yields a composition‐dependent spectral redistribution, including the emergence of an additional long‐wavelength spectral feature in the core–satellite assemblies. Wavelength‐dependent surface‐enhanced Raman scattering measurements reveal contrasting responses under 633 and 785 nm excitation, reflecting redistribution of local plasmonic coupling pathways. These results provide process‐enabled guidelines for using meniscus‐guided 3D‐nanoprinting to realize robust nanoparticle assemblies. article_number: e71686 article_type: original author: - first_name: Vasanthan full_name: Devaraj, Vasanthan id: '103814' last_name: Devaraj - first_name: Sunghyun full_name: Kwak, Sunghyun last_name: Kwak - first_name: Hyeongjip full_name: Kim, Hyeongjip last_name: Kim - first_name: Sang‐Keun full_name: Sung, Sang‐Keun last_name: Sung - first_name: Jong‐Min full_name: Lee, Jong‐Min last_name: Lee - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 - first_name: Won‐Geun full_name: Kim, Won‐Geun last_name: Kim citation: ama: Devaraj V, Kwak S, Kim H, et al.

However, its multimode nature also makes it challenging to measure its properties. Recently [I. Barakat et al., Optica Quantum 3, 36 (2025)], a technique for the simultaneous measurement of squeezing of multiple broadband modes based on a phase-sensitive amplification approach was experimentally implemented using a setup that effectively corresponds to an SU(1,1) interferometer. Here, we aim to provide a complete theoretical analysis of the modal structure of (generally unbalanced) SU(1,1) interferometers and a detailed theoretical formal derivation of the framework for this technique. Utilizing the joint Schmidt decomposition of the transfer functions, we investigate the shape and phase profiles of the modes of the SU(1,1) interferometer and its components [parametric down-conversion (PDC) sections] for different parametric gain regimes. We discover a complicated interplay between the PDC modes and the modes of the entire interferometer, and analyze it by using their overlap coefficients as a similarity measure. Finally, we develop a rigorous processing method for the aforementioned multimode squeezing measurement technique and discuss necessary approximations to make this method experimentally feasible. article_number: '033139' article_type: original author: - first_name: Dennis full_name: Scharwald, Dennis id: '55907' last_name: Scharwald orcid: 0009-0007-5654-5412 - first_name: Polina full_name: Sharapova, Polina id: '60286' last_name: Sharapova citation: ama: Scharwald D, Sharapova P.
