We consider spherical clusters, thick layers and monolayers with realistic topologies and dimensions much larger than the wavelength of light. The maximum bulk packing density of clusters is 0.5. A numerically exact solution of the electromagnetic problem is obtained using the Discontinuous Galerkin Time Domain method and with application of high- performance computing. We show that high packing density causes light localization in such structures which makes an impact on the opposition phenomena: backscattering intensity surge and negative linear polarization feature. Diffuse multiple scattering is significantly reduced in the case of non-absorbing particles and near-field interaction results in a percolation-like light transport determined by the topology of the medium. With this the negative polarization feature caused by single scattering gets enhanced if compared to lower density samples. We also confirm coherent double scattering mechanism of negative polarization for light scattered from dense absorbing slabs. In this case convergent result for the scattering angle polarization dependency at backscattering can be obtained for a layer of just a few tens of particles if they are larger than the wavelength.","lang":"eng"}],"publication":"Springer Series in Light Scattering - Volume 8: Light Polarization and Multiple Scattering in Turbid Media","type":"book_chapter","keyword":["tet_topic_scattering"],"department":[{"_id":"61"},{"_id":"230"},{"_id":"429"}],"file":[{"creator":"fossie","date_created":"2022-09-22T09:24:45Z","file_size":1525307,"access_level":"local","file_name":"2022-09 Grynko - Book chapter on Light Scattering by Large Densely Packed Clusters of Particles.pdf","date_updated":"2022-09-22T09:24:45Z","relation":"main_file","content_type":"application/pdf","file_id":"33467"}],"date_created":"2022-09-22T09:18:45Z","has_accepted_license":"1","status":"public","user_id":"158","ddc":["530"],"volume":8,"editor":[{"first_name":"Alexander","last_name":"Kokhanovsky","full_name":"Kokhanovsky, Alexander"}],"_id":"33466","publisher":"Springer International Publishing","project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"file_date_updated":"2022-09-22T09:24:45Z","citation":{"ama":"Grynko Y, Shkuratov Y, Alhaddad S, Förstner J.

However, during the joint preparation for the MA, geometric features of the joint can change due to elastic effects and closing cracks. X-ray computed tomography (CT) is a promising alternative to investigate the joint non-destructively. However, if the\r\nmaterial properties of similar joining partners are the same, the CT is not able to correctly resolve surfaces in the joint that are close to or pressing onto each other. These surfaces are relevant for the determination of characteristic dimensions such as neck thickness and undercut. By placing a thin, highly radiopaque tin layer between the joining partners, the interfacial area in the reconstructed volume can be highlighted. In this work, a method for the localisation of the tin layer inside the joint as well as threshold value procedures for the outer joint contour in cross section images are investigated. The measured characteristic dimensions are compared with measured values from MA of the same samples and of samples without tin layer.

In this paper\r\nwe investigate the hardness of classically simulating the QSVT. A recent result\r\nby Chia, Gily\\'en, Li, Lin, Tang and Wang (STOC 2020) showed that the QSVT can\r\nbe efficiently \"dequantized\" for low-rank matrices, and discussed its\r\nimplication to quantum machine learning. In this work, motivated by\r\nestablishing the superiority of quantum algorithms for quantum chemistry and\r\nmaking progress on the quantum PCP conjecture, we focus on the other main class\r\nof matrices considered in applications of the QSVT, sparse matrices.\r\n  We first show how to efficiently \"dequantize\", with arbitrarily small\r\nconstant precision, the QSVT associated with a low-degree polynomial. We apply\r\nthis technique to design classical algorithms that estimate, with constant\r\nprecision, the singular values of a sparse matrix. We show in particular that a\r\ncentral computational problem considered by quantum algorithms for quantum\r\nchemistry (estimating the ground state energy of a local Hamiltonian when\r\ngiven, as an additional input, a state sufficiently close to the ground state)\r\ncan be solved efficiently with constant precision on a classical computer. As a\r\ncomplementary result, we prove that with inverse-polynomial precision, the same\r\nproblem becomes BQP-complete. This gives theoretical evidence for the\r\nsuperiority of quantum algorithms for chemistry, and strongly suggests that\r\nsaid superiority stems from the improved precision achievable in the quantum\r\nsetting. We also discuss how this dequantization technique may help make\r\nprogress on the central quantum PCP conjecture."}],"external_id":{"arxiv":["2111.09079"]},"date_created":"2021-11-18T07:32:56Z","type":"conference","department":[{"_id":"623"},{"_id":"7"}],"oa":"1","title":"Dequantizing the Quantum Singular Value Transformation: Hardness and  Applications to Quantum Chemistry and the Quantum PCP Conjecture","status":"public","year":"2022","author":[{"id":"71541","full_name":"Gharibian, Sevag","last_name":"Gharibian","orcid":"0000-0002-9992-3379","first_name":"Sevag"},{"first_name":"François Le","last_name":"Gall","full_name":"Gall, François Le"}],"publication_status":"published","date_updated":"2023-10-09T04:17:29Z","page":"19-32","main_file_link":[{"url":"https://arxiv.org/abs/2111.09079","open_access":"1"}],"_id":"27531","language":[{"iso":"eng"}],"user_id":"71541"},{"publication":"Journal of Applied Physics","issue":"24","abstract":[{"text":"Recent analyses by polarization resolved second-harmonic (SH) microscopy have demonstrated that ferroelectric (FE) domain walls (DWs) can possess non-Ising wall characteristics and topological nature. These analyses rely on locally analyzing the properties, directionality, and magnitude of the second-order nonlinear tensor. However, when inspecting FE DWs with SH microscopy, a manifold of different effects may contribute to the observed signal difference between domains and DWs, i.e., far-field interference, Čerenkov-type phase-matching (CSHG), and changes in the aforementioned local nonlinear optical properties. They all might be present at the same time and, therefore, require careful interpretation and separation. In this work, we demonstrate how the particularly strong Čerenkov-type contrast can selectively be blocked using dark- and bright-field SH microscopy. Based on this approach, we show that other contrast mechanisms emerge that were previously overlayed by CSHG but can now be readily selected through the appropriate experimental geometry. Using the methods presented, we show that the strength of the CSHG contrast compared to the other mechanisms is approximately 22 times higher. This work lays the foundation for the in-depth analysis of FE DW topologies by SH microscopy.","lang":"eng"}],"extern":"1","date_created":"2023-10-11T08:53:25Z","keyword":["General Physics and Astronomy"],"type":"journal_article","publication_identifier":{"issn":["0021-8979","1089-7550"]},"author":[{"full_name":"Hegarty, Peter A.","last_name":"Hegarty","first_name":"Peter A."},{"full_name":"Beccard, Henrik","first_name":"Henrik","last_name":"Beccard"},{"last_name":"Eng","first_name":"Lukas M.","full_name":"Eng, Lukas M."},{"orcid":"0000-0003-4682-4577","first_name":"Michael","last_name":"Rüsing","full_name":"Rüsing, Michael","id":"22501"}],"title":"Turn all the lights off: Bright- and dark-field second-harmonic microscopy to select contrast mechanisms for ferroelectric domain walls","year":"2022","intvolume":"       131","article_type":"original","date_updated":"2023-10-11T08:53:55Z","publication_status":"published","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":" https://doi.org/10.1063/5.0094988"}],"doi":"10.1063/5.0094988","citation":{"short":"P.A.

Coherent, nonlinear optical (NLO) μ-spectroscopy offers insight into the local thickness, stacking order, symmetry, or electronic and vibrational properties. Thin films and 2D materials are usually supported on multi-layered substrates leading to (multi-)reflections, interference, or phase jumps at interfaces during μ-spectroscopy, which all can make the interpretation of experiments particularly challenging. The disentanglement of the influence parameters can be achieved via rigorous theoretical analysis. In this work, we compare two self-developed modeling approaches, a semi-analytical and a fully vectorial model, to experiments carried out in thin-film geometry for two archetypal NLO processes, second-harmonic and third-harmonic generation. In particular, we demonstrate that thin-film interference and phase matching do heavily influence the signal strength. Furthermore, we work out key differences between three and four photon processes, such as the role of the Gouy-phase shift and the focal position. Last, we can show that a relatively simple semi-analytical model, despite its limitations, is able to accurately describe experiments at a significantly lower computational cost as compared to a full vectorial modeling. This study lays the groundwork for performing quantitative NLO μ-spectroscopy on thin films and 2D materials, as it identifies and quantifies the impact of the corresponding sample and setup parameters on the NLO signal, in order to distinguish them from genuine material properties.<"}],"date_created":"2023-10-11T08:59:23Z","type":"journal_article","keyword":["General Physics and Astronomy"]},{"language":[{"iso":"eng"}],"article_number":" e2022001","main_file_link":[{"open_access":"1","url":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/zaac.202200193"}],"doi":"10.1002/zaac.202200193","publication_identifier":{"issn":["0044-2313","1521-3749"]},"author":[{"last_name":"Li","first_name":"Yuxi","full_name":"Li, Yuxi"},{"full_name":"Hegarty, Peter A.","last_name":"Hegarty","first_name":"Peter A."},{"id":"22501","full_name":"Rüsing, Michael","orcid":"0000-0003-4682-4577","last_name":"Rüsing","first_name":"Michael"},{"last_name":"Eng","first_name":"Lukas M.","full_name":"Eng, Lukas M."},{"last_name":"Ruck","first_name":"Michael","full_name":"Ruck, Michael"}],"title":"Ba(BO2OH) – A Monoprotonated Monoborate from Hydroflux Showing Intense Second Harmonic Generation","year":"2022","article_type":"original","intvolume":"       648","publication_status":"published","date_updated":"2023-10-11T08:59:51Z","date_created":"2023-10-11T08:56:26Z","type":"journal_article","keyword":["Inorganic Chemistry"],"issue":"21","publication":"Zeitschrift für anorganische und allgemeine Chemie","extern":"1","abstract":[{"text":"<jats:title>Abstract</jats:title><jats:p>Pure samples of colorless, air‐stable Ba(BO<jats:sub>2</jats:sub>OH) crystals were obtained from Ba(NO<jats:sub>3</jats:sub>)<jats:sub>2</jats:sub> and H<jats:sub>3</jats:sub>BO<jats:sub>3</jats:sub> under the ultra‐alkaline conditions of a KOH hydroflux at about 250 °C.

Under the condition of normal dispersion, i.e., the refractive index at the SH wavelength is larger as compared to the refractive index at the fundamental wavelength, n(2ω)>n(ω), bulk crystals will generate no SH signal. Should the bulk, however, contain DWs, an appreciable SH signal will still be detectable at the location of DWs stemming from the Čerenkov mechanism. In this work, we demonstrate both how SH signals are generated in bulk media and how the Čerenkov mechanism can be inhibited by using anomalous dispersion, i.e., n(ω)<n(2ω). This allows us to quantitatively estimate the relative strength of the Čerenkov compared to other SH contrast mechanisms in DWs, such as the interference contrast. The results are in agreement with previous experiments based on the geometric separation of the signals. Due to the observed, strong Čerenkov contrast, such signal contributions may not be neglected in polarimetry studies of ferroelectric DWs in the future.","lang":"eng"}],"publication":"Journal of Applied Physics","issue":"21","type":"journal_article","keyword":["General Physics and Astronomy"],"date_created":"2023-10-11T08:57:55Z","status":"public","volume":132,"user_id":"22501","_id":"47988","funded_apc":"1","publisher":"AIP Publishing","page":"214102","quality_controlled":"1","citation":{"short":"P.A.

Training and evaluation of these single tasks requires synthetic\r\ndata with access to intermediate signals that is as close as possible to the\r\nevaluation scenario. As such data often is not available, many works instead\r\nuse specialized databases for the training of each system component, e.g\r\nWSJ0-mix for source separation. We present a Multi-purpose Multi-Speaker\r\nMixture Signal Generator (MMS-MSG) for generating a variety of speech mixture\r\nsignals based on any speech corpus, ranging from classical anechoic mixtures\r\n(e.g., WSJ0-mix) over reverberant mixtures (e.g., SMS-WSJ) to meeting-style\r\ndata.

Such labels are required when training a neural network for object recognition from radar data. The automatic labeling approach rests on the simultaneous recording of camera and lidar data in addition to the radar spectrum. By warping radar spectra into the camera image, state-of-the-art object recognition algorithms can be applied to label relevant objects, such as cars, in the camera image. The warping operation is designed to be fully differentiable, which allows backpropagating the gradient computed on the camera image through the warping operation to the neural network operating on the radar data. As the warping operation relies on accurate scene flow estimation, we further propose a novel scene flow estimation algorithm which exploits information from camera, lidar and radar sensors. The\r\nproposed scene flow estimation approach is compared against a state-of-the-art scene flow algorithm, and it outperforms it by approximately 30% w.r.t. mean average error. The feasibility of the overall framework for automatic label generation for\r\nRD spectra is verified by evaluating the performance of neural networks trained with the proposed framework for Direction-of-Arrival estimation."}],"issue":"9","publication":"IEEE Transactions on Vehicular Technology","ddc":["000"],"user_id":"242","volume":71,"page":"9435-9449","_id":"33451","has_accepted_license":"1","status":"public","oa":"1","quality_controlled":"1","file_date_updated":"2022-09-22T07:00:29Z","citation":{"mla":"Grimm, Christopher, et al. “Warping of Radar Data Into Camera Image for Cross-Modal Supervision in Automotive Applications.” <i>IEEE Transactions on Vehicular Technology</i>, vol. 71, no. 9, 2022, pp. 9435–49, doi:<a href=\"https://doi.org/10.1109/TVT.2022.3182411\">10.1109/TVT.2022.3182411</a>.","ama":"Grimm C, Fei T, Warsitz E, Farhoud R, Breddermann T, Haeb-Umbach R.
