Due to these advantageous properties, PC is often used in industry for example in medical devices, automotive headlamps, sporting equipment, electronics, and a variety of other products. PC is often subjected to uniaxial and biaxial loading conditions. Therefore, reliable material models have to take into account the various resulting experimental effects. For those reasons, we investigate PC specimens under uniaxial and biaxial loading by using different stretch rates and loading scenarios. In addition to that, we propose methods for optical measurement of local stretches to obtain the approximated local true stress. In future work, the displacement fields and the resulting reaction forces will be used for parameter identification of constitutive equations. author: - first_name: Ayoub full_name: Hamdoun, Ayoub last_name: Hamdoun - first_name: Rolf full_name: Mahnken, Rolf id: '335' last_name: Mahnken citation: ama: Hamdoun A, Mahnken R.

However, BCARS encounters spectral distortion due to a setup-dependent non-resonant background (NRB). This study assesses BCARS reproducibility through a round robin experiment using two distinct BCARS setups and crystalline materials with varying structural complexity, including diamond, 6H-SiC, KDP, and KTP. The analysis compares setup-specific NRB correction procedures, detected and NRB-removed spectra, and mode assignment. We determine the influence of BCARS setup parameters like pump wavelength, pulse width, and detection geometry and provide a practical guide for optimizing BCARS setups for solid-state applications. article_number: '112' article_type: original author: - first_name: Franz full_name: Hempel, Franz last_name: Hempel - first_name: Federico full_name: Vernuccio, Federico last_name: Vernuccio - first_name: Lukas full_name: König, Lukas last_name: König - first_name: Robin full_name: Buschbeck, Robin last_name: Buschbeck - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 - first_name: Giulio full_name: Cerullo, Giulio last_name: Cerullo - first_name: Dario full_name: Polli, Dario last_name: Polli - first_name: Lukas M. full_name: Eng, Lukas M. last_name: Eng citation: ama: 'Hempel F, Vernuccio F, König L, et al.

Diagonally implicit Runge–Kutta (DIRK) methods are the most popular class among the diverse family of Runge–Kutta algorithms. In this paper, the novel class of low‐order explicit last‐stage diagonally implicit Runge–Kutta (ELDIRK) methods are explored, which combine implicit schemes with an additional explicit evaluation as an explicit last stage. ELDIRK Butcher tableaus are used to control embedded RK methods to obtain solutions of different orders. The lower‐order solution is obtained by classical implicit RK stages and the higher‐order solution is obtained by additional explicit evaluation. As a result, a significant reduction in computational cost is achieved by skipping the iterative solution of nonlinear systems for the additional step. The examination of the heat problem and the use of the innovative Butcher tableau in the finite‐element method are the main contributions of this work. Thus, it is possible to establish adaptive step size control for the new low‐order embedded methods based on an empirical method for error estimation. Two‐dimensional simulations are used to show an appropriate algorithm for the ELDIRK schemes. The new Runge–Kutta schemes' predictions of higher‐order convergence are confirmed, and their successful outcomes are illustrated. author: - first_name: Hendrik full_name: Westermann, Hendrik id: '60816' last_name: Westermann orcid: 0000-0002-5034-9708 - first_name: Rolf full_name: Mahnken, Rolf id: '335' last_name: Mahnken citation: ama: Westermann H, Mahnken R.

However, readout and driving electronics can introduce detrimental parasitic effects. Here we show an all-optical control and readout of a superconducting nanowire single photon detector (SNSPD), completely electrically decoupled from room temperature electronics. We provide the operation power for the superconducting detector via a cryogenic photodiode, and readout single photon detection signals via a cryogenic electro-optic modulator in the same cryostat. This method opens the possibility for control and readout of superconducting circuits, and feedforward for photonic quantum computing. article_number: '32717' author: - first_name: Frederik full_name: Thiele, Frederik id: '50819' last_name: Thiele orcid: 0000-0003-0663-5587 - first_name: Thomas full_name: Hummel, Thomas id: '83846' last_name: Hummel - first_name: Adam N. full_name: McCaughan, Adam N. last_name: McCaughan - first_name: Julian full_name: Brockmeier, Julian id: '44807' last_name: Brockmeier - first_name: Maximilian full_name: Protte, Maximilian id: '46170' last_name: Protte - first_name: Victor full_name: Quiring, Victor last_name: Quiring - first_name: Sebastian full_name: Lengeling, Sebastian id: '44373' last_name: Lengeling - first_name: Christof full_name: Eigner, Christof id: '13244' last_name: Eigner orcid: https://orcid.org/0000-0002-5693-3083 - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn - first_name: Tim full_name: Bartley, Tim id: '49683' last_name: Bartley citation: ama: Thiele F, Hummel T, McCaughan AN, et al.

These methods are particularly advantageous to account for microstructural mechanisms which can be related to nonlinearities and time‐dependency due to elasto‐plasticity behavior. However, their advantages are diminished by increasing computational demand. The present contribution deals with the balance of accuracy and numerical efficiency of nonlinear homogenization associated with a framework of goal‐oriented adaptivity, which takes into account error accumulation over time. To this end, model adaptivity of homogenization methods is coupled to mesh adaptivity on the macro scale. Our new proposed adaptive procedure is driven by a goal‐oriented a posteriori error estimator based on duality techniques using downwind and upwind approximations. Due to nonlinearities and time‐dependency of the plasticity, the estimation of error transport and error generation is obtained with a backward‐in‐time dual method despite a high demand on memory capacity. In this contribution, the dual problem is solved with a forward‐in‐time dual method that allows estimating the full error during the resolution of the primal problem without the need for extra memory capacity. Finally, a numerical example illustrates the effectiveness of the proposed adaptive approach. author: - first_name: Arnold full_name: Tchomgue Simeu, Arnold id: '83075' last_name: Tchomgue Simeu - first_name: Rolf full_name: Mahnken, Rolf id: '335' last_name: Mahnken citation: ama: Tchomgue Simeu A, Mahnken R.

The behavior of CBS is simulated with a micropolar model, whereby the additional degree of freedom of the model describes the rotation of the sand grains. The model is used to generate a shear band under pressure for three different meshes, where the force‐displacement curves of the three meshes converge so that no mesh dependence occurs. Another requirement of the model is the consideration of asymmetric behavior for compression and tension. Due to the additional degree of freedom the implicit implementation of the micropolar continuum is very time‐consuming. Therefore, an explicit implementation is considered as an alternative possibility. This paper compares the advantages and disadvantages of both methods and the results for both calculations. author: - first_name: Alexander full_name: Börger, Alexander last_name: Börger - first_name: Rolf full_name: Mahnken, Rolf id: '335' last_name: Mahnken citation: ama: Börger A, Mahnken R.

We theoretically and experimentally reveal that when the structural symmetry of the meta-atom is incompatible with the lattice symmetry of an array, some generalized nonlinear geometric phases appear, which offers new possibilities for harmonic generation control beyond the accessible symmetries governed by the selection rule. The underlying mechanism is attributed to the modified rotation of the effective principal axis of a dense meta-atom array, where the strong coupling among the units gives rise to a generalized linear geometric phase modulation of the pump light. Therefore, nonlinear geometric phases carried by third-harmonic emissions are the natural result of the wave-mixing process among the modes excited at the fundamental frequency. This mechanism further points out a new strategy to predict the nonlinear geometric phases delivered by the nanostructures according to their linear responses. Our design is simple and efficient and offers alternatives for the nonlinear meta-devices that are capable of flexible photon generation and manipulation. article_type: original author: - first_name: Bingyi full_name: Liu, Bingyi last_name: Liu - first_name: René full_name: Geromel, René last_name: Geromel - first_name: Zhaoxian full_name: Su, Zhaoxian last_name: Su - first_name: Kai full_name: Guo, Kai last_name: Guo - first_name: Yongtian full_name: Wang, Yongtian last_name: Wang - first_name: Zhongyi full_name: Guo, Zhongyi last_name: Guo - first_name: Lingling full_name: Huang, Lingling last_name: Huang - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 citation: ama: Liu B, Geromel R, Su Z, et al.

Their appearance was explained by geometric optics and total internal reflection. The setae also increase the emissivity of the ant, as they form an effective medium. This work provides additional data on microstructural details of the setae that are used to simulate the scattering of an individual seta to explain their influence on the optical properties. This is achieved by characterization of their structure using light microscopy and scanning/transmission electron microscopy. How the microstructural features influence scattering is investigated wave-optically within the limits of finite-difference time-domain simulations from the ultraviolet to the mid-infrared spectral range to elucidate the optical effects beyond ray optics and effective medium theory. The results show that Mie scattering plays an important role in protecting the ant from solar radiation and could be relevant for its thermal tolerance. article_type: original author: - first_name: Bertram full_name: Schwind, Bertram last_name: Schwind - first_name: Xia full_name: Wu, Xia last_name: Wu - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Helge-Otto full_name: Fabritius, Helge-Otto last_name: Fabritius citation: ama: Schwind B, Wu X, Tiemann M, Fabritius H-O.

Twenty-four female footballers (14.9 ± 0.9 year) performed unanticipated cutting maneuvers in a laboratory setting and on the football pitch during football-specific exercises (F-EX) and games (F-GAME). Knee joint moments were collected in the laboratory and grouped using hierarchical agglomerative clustering. The clusters were used to investigate the kinematics collected on field through wearable sensors. Three clusters emerged: Cluster 1 presented the lowest knee moments; Cluster 2 presented high knee extension but low knee abduction and rotation moments; Cluster 3 presented the highest knee abduction, extension, and external rotation moments. In F-EX, greater knee abduction angles were found in Cluster 2 and 3 compared to Cluster 1 (p = 0.007). Cluster 2 showed the lowest knee and hip flexion angles (p < 0.013). Cluster 3 showed the greatest hip external rotation angles (p = 0.006). In F-GAME, Cluster 3 presented the greatest knee external rotation and lowest knee flexion angles (p = 0.003). Clinically relevant differences towards ACL injury identified in the laboratory reflected at-risk patterns only in part when cutting on the field: in the field, low-risk players exhibited similar kinematic patterns as the high-risk players. Therefore, in-lab injury risk screening may lack ecological validity.' article_number: '2176' author: - first_name: Stefano full_name: Di Paolo, Stefano last_name: Di Paolo - first_name: Eline M. full_name: Nijmeijer, Eline M. last_name: Nijmeijer - first_name: Laura full_name: Bragonzoni, Laura last_name: Bragonzoni - first_name: Alli full_name: Gokeler, Alli last_name: Gokeler - first_name: Anne full_name: Benjaminse, Anne last_name: Benjaminse citation: ama: 'Di Paolo S, Nijmeijer EM, Bragonzoni L, Gokeler A, Benjaminse A.

The situation is, however, different in solid-state systems as it has been demonstrated that due to collisions with neighboring atomic cores of the crystal lattice strong HHG can be generated even by elliptically- and circularly-polarized laser fields. Here we apply PG to solid-state systems and find that the conventional PG technique is inefficient for the generation of isolated ultrashort harmonic pulse bursts. In contrast, we demonstrate that a polarization-skewed laser pulse is able to confine the harmonic emission to a time window of less than one-tenth of the laser cycle. This method provides a novel way to control HHG and to generate isolated attosecond pulses in solids. article_number: '18862' author: - first_name: Xiaohong full_name: Song, Xiaohong last_name: Song - first_name: Shidong full_name: Yang, Shidong last_name: Yang - first_name: Guifang full_name: Wang, Guifang last_name: Wang - first_name: Jianpeng full_name: Lin, Jianpeng last_name: Lin - first_name: Liang full_name: Wang, Liang last_name: Wang - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: Weifeng full_name: Yang, Weifeng last_name: Yang citation: ama: Song X, Yang S, Wang G, et al.

It is advantageous to operate the systems at telecommunication wavelengths and to integrate the setups for these applications in order to improve stability, compactness and scalability. A new promising material platform for integrated quantum optics is lithium niobate on insulator (LNOI). 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. This lays the foundation for more sophisticated quantum experiments in LNOI. article_number: '23140' author: - first_name: Silia full_name: Babel, Silia id: '63231' last_name: Babel orcid: https://orcid.org/0000-0002-1568-2580 - first_name: Laura full_name: Bollmers, Laura id: '61375' last_name: Bollmers - first_name: Marcello full_name: Massaro, Marcello id: '59545' last_name: Massaro orcid: 0000-0002-2539-7652 - first_name: Kai Hong full_name: Luo, Kai Hong id: '36389' last_name: Luo orcid: 0000-0003-1008-4976 - first_name: Michael full_name: Stefszky, Michael id: '42777' last_name: Stefszky - first_name: Federico full_name: Pegoraro, Federico id: '88928' last_name: Pegoraro - first_name: Philip full_name: Held, Philip id: '68236' last_name: Held - first_name: Harald full_name: Herrmann, Harald id: '216' last_name: Herrmann - first_name: Christof full_name: Eigner, Christof id: '13244' last_name: Eigner orcid: https://orcid.org/0000-0002-5693-3083 - first_name: Benjamin full_name: Brecht, Benjamin id: '27150' last_name: Brecht orcid: '0000-0003-4140-0556 ' - first_name: Laura full_name: Padberg, Laura id: '40300' last_name: Padberg - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn citation: ama: Babel S, Bollmers L, Massaro M, et al.

A continuous-wave laser beam is delivered and the squeezed field is collected by single-mode fibers; up to −3.17(9) dB of useful squeezing is available in fibers. To showcase the usefulness of such a fiber-coupled device, we applied the generated squeezed light in a fiber-based phase sensing experiment, showing a quantum enhancement in the signal-to-noise ratio of 0.35 dB. Moreover, our investigation of the effect of photorefraction on the cavity resonance condition suggests that it causes system instabilities at high powers. article_number: '2999' article_type: original author: - first_name: Renato full_name: Domeneguetti, Renato last_name: Domeneguetti - first_name: Michael full_name: Stefszky, Michael id: '42777' last_name: Stefszky - first_name: Harald full_name: Herrmann, Harald id: '216' last_name: Herrmann - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn - first_name: Ulrik L. full_name: Andersen, Ulrik L. last_name: Andersen - first_name: Jonas S. full_name: Neergaard-Nielsen, Jonas S. last_name: Neergaard-Nielsen - first_name: Tobias full_name: Gehring, Tobias last_name: Gehring citation: ama: Domeneguetti R, Stefszky M, Herrmann H, et al.
