[{"type":"journal_article","publication":"Entropy","status":"public","abstract":[{"text":"We present a novel approach to characterize and quantify microheterogeneity and microphase separation in computer simulations of complex liquid mixtures. Our post-processing method is based on local density fluctuations of the different constituents in sampling spheres of varying size. It can be easily applied to both molecular dynamics (MD) and Monte Carlo (MC) simulations, including periodic boundary conditions. Multidimensional correlation of the density distributions yields a clear picture of the domain formation due to the subtle balance of different interactions. We apply our approach to the example of force field molecular dynamics simulations of imidazolium-based ionic liquids with different side chain lengths at different temperatures, namely 1-ethyl-3-methylimidazolium chloride, 1-hexyl-3-methylimidazolium chloride, and 1-decyl-3-methylimidazolium chloride, which are known to form distinct liquid domains. We put the results into the context of existing microheterogeneity analyses and demonstrate the advantages and sensitivity of our novel method. Furthermore, we show how to estimate the configuration entropy from our analysis, and we investigate voids in the system. The analysis has been implemented into our program package TRAVIS and is thus available as free software.","lang":"eng"}],"user_id":"24135","department":[{"_id":"27"},{"_id":"518"},{"_id":"803"}],"project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"_id":"53474","language":[{"iso":"eng"}],"article_number":"322","issue":"4","publication_status":"published","publication_identifier":{"issn":["1099-4300"]},"citation":{"short":"M.

A characteristic material property for polymers is the low thermal conductivity. However, for specific applications, such as additively manufactured injection molding tool inserts, increased thermal conductivity is advantageous. In this study, the influence of fillers of different types, shapes and sizes on the resulting thermal conductivity of compounds is investigated. The aim is to analyze the effects of the fillers, considering the FFF-typical strand structure. The first step is to characterize the fillers in terms of shape and size. Based on this, the resulting thermal conductivity of specimens manufactured in the FFF process for different build orientations is specifically examined and compared to injection molding. This ensures that the process- and material-related anisotropy of the specimens is considered in the analysis. For the evaluation, a methodology is developed to be applied in Laser Flash Analysis (LFA), which allows the results to be evaluated despite the characteristic FFF surface structure. For the final visualization of the influence of the particle size on the particle orientation, Scanning Electron Microscopy (SEM) images of the relevant polymer compounds are made. The investigations provide a data basis regarding the influence of the particle type, shape and size on the thermal conductivity as well as for the requirement-oriented selection of fillers for processing thermally conductive polymer compounds in the FFF process."}],"status":"public","_id":"53529","department":[{"_id":"624"},{"_id":"367"},{"_id":"321"},{"_id":"9"}],"user_id":"70729","language":[{"iso":"eng"}]},{"title":"Noctua 2 Supercomputer","date_created":"2024-04-26T07:39:41Z","year":"2024","language":[{"iso":"eng"}],"ddc":["004"],"keyword":["Noctua 2","Supercomputer","FPGA","PC2","Paderborn Center for Parallel Computing"],"file":[{"file_size":3825480,"file_name":"Noctua2_Supercomputer.pdf","file_id":"53664","access_level":"open_access","date_updated":"2024-04-26T08:35:17Z","date_created":"2024-04-26T07:30:20Z","creator":"deffel","relation":"main_file","content_type":"application/pdf"}],"abstract":[{"text":"Noctua 2 is a supercomputer operated at the Paderborn Center for Parallel Computing (PC2) at Paderborn University in Germany.

These parameters were experimentally characterized and simulated by finite difference time domain simulations to elucidate the optical impact of the setae in the mid infrared range and the contribution of leaky mode resonances.

Here, we show that a characteristic dependence of the width of the temporal interferogram can be exploited to obtain insights into the amount of second-order dispersion inside the interferometer and to retrieve actual and Fourier-limited ultrashort biphoton correlation times of around 100 fs.

The heats of fusion of the end members, given by DTA measurements, are 103 kJ/mol at 1531 K for LN and 289 kJ/mol at 1913 K for LT. These values were used as input parameters to generate the data. This data served as the basis for calculating a phase diagram for LN-LT solid solutions. Finally, based on the experimental data and a thermodynamic solution model, the Calphad Factsage module optimized the phase diagram. We also generated thermodynamic parameters for Gibbs’ excess energy of the solid solution. A plot of the segregation coefficient as a function of Ta concentration was derived from the phase diagram."}],"status":"public","publication":"Journal of Materials Science","type":"journal_article","title":"Evaluation and thermodynamic optimization of phase diagram of lithium niobate tantalate solid solutions","doi":"10.1007/s10853-024-09932-7","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1007/s10853-024-09932-7"}],"oa":"1","publisher":"Springer Science and Business Media LLC","date_updated":"2024-07-05T06:49:25Z","author":[{"last_name":"Bashir","full_name":"Bashir, Umar","first_name":"Umar"},{"last_name":"Klimm","full_name":"Klimm, Detlef","first_name":"Detlef"},{"first_name":"Michael","last_name":"Rüsing","orcid":"0000-0003-4682-4577","id":"22501","full_name":"Rüsing, Michael"},{"first_name":"Matthias","full_name":"Bickermann, Matthias","last_name":"Bickermann"},{"first_name":"Steffen","last_name":"Ganschow","full_name":"Ganschow, Steffen"}],"date_created":"2024-07-05T06:47:53Z","year":"2024","citation":{"apa":"Bashir, U., Klimm, D., Rüsing, M., Bickermann, M., &#38; Ganschow, S.

We find that the rising edge as well as the amplitude of the electrical signal have the most dependence on photon number. Accurately measuring the rising edge while simultaneously measuring the voltage of the pulse amplitude maximizes the photon-number resolution of SNSPDs. Using an optimal basis of principal components, we show unambiguous discrimination between one- and two-photon events, as well as partial resolution up to five photons. This expands the use case of SNSPDs to photon-counting experiments, without the need of detector multiplexing architectures.</jats:p>\r\n          <jats:sec>\r\n            <jats:title/>\r\n            <jats:supplementary-material>\r\n              <jats:permissions>\r\n                <jats:copyright-statement>Published by the American Physical Society</jats:copyright-statement>\r\n                <jats:copyright-year>2024</jats:copyright-year>\r\n              </jats:permissions>\r\n            </jats:supplementary-material>\r\n          </jats:sec>"}],"publication":"Physical Review Applied","doi":"10.1103/physrevapplied.22.014024","main_file_link":[{"open_access":"1"}],"oa":"1","date_updated":"2024-07-11T09:36:00Z","volume":22,"author":[{"full_name":"Schapeler, Timon","id":"55629","last_name":"Schapeler","orcid":"0000-0001-7652-1716","first_name":"Timon"},{"last_name":"Lamberty","full_name":"Lamberty, Niklas","first_name":"Niklas"},{"first_name":"Thomas","orcid":"0000-0001-8627-2119","last_name":"Hummel","id":"83846","full_name":"Hummel, Thomas"},{"id":"63579","full_name":"Schlue, Fabian","last_name":"Schlue","first_name":"Fabian"},{"first_name":"Michael","last_name":"Stefszky","id":"42777","full_name":"Stefszky, Michael"},{"orcid":"0000-0003-4140-0556 ","last_name":"Brecht","full_name":"Brecht, Benjamin","id":"27150","first_name":"Benjamin"},{"full_name":"Silberhorn, Christine","id":"26263","last_name":"Silberhorn","first_name":"Christine"},{"first_name":"Tim","full_name":"Bartley, Tim","id":"49683","last_name":"Bartley"}],"intvolume":"        22","citation":{"chicago":"Schapeler, Timon, Niklas Lamberty, Thomas Hummel, Fabian Schlue, Michael Stefszky, Benjamin Brecht, Christine Silberhorn, and Tim Bartley. “Electrical Trace Analysis of Superconducting Nanowire Photon-Number-Resolving Detectors.” <i>Physical Review Applied</i> 22, no. 1 (2024). <a href=\"https://doi.org/10.1103/physrevapplied.22.014024\">https://doi.org/10.1103/physrevapplied.22.014024</a>.","ieee":"T.

However, the tunneling dynamics in solids, especially nonadiabatic tunneling, has not yet been fully understood. Here, we study the sub-cycle resolved strong-field tunneling dynamics in solids via a complex saddle-point method. We compare the instantaneous momentum at the moment of tunneling and the tunneling distances over a range of Keldysh parameters. Our results demonstrate that for nonadiabatic tunneling, tunneling ionization away from Γ point is possible. When this happens the electron has a nonzero initial velocity when it emerges in the conduction band. Moreover, consistent with atomic tunneling, a reduced tunneling distance as compared to the quasi-static case is found. Our results provide remarkable insight into the basic physics governing the sub-cycle electron tunneling dynamics with significant implications for understanding subsequent strong-field nonlinear phenomena in solids.</jats:p>"}],"publication":"Optics Express","type":"journal_article","language":[{"iso":"eng"}],"article_number":"15862","department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"35"}],"user_id":"16199","_id":"55264"},{"publication":"Physical Review B","language":[{"iso":"eng"}],"issue":"7","year":"2024","publisher":"American Physical Society (APS)","date_created":"2024-07-15T09:47:27Z","title":"Optical Stark effect in type-II semiconductor heterostructures","type":"journal_article","status":"public","_id":"55267","project":[{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"grant_number":"231447078","name":"TRR 142: TRR 142 - Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen","_id":"53"},{"grant_number":"231447078","name":"TRR 142 - A10: TRR 142 - Nichtlinearitäten von atomar dünnen Übergangsmetall-Dichalkogeniden in starken Feldern (A10)","_id":"165"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"27"}],"user_id":"16199","article_number":"075301","publication_identifier":{"issn":["2469-9950","2469-9969"]},"publication_status":"published","intvolume":"       109","citation":{"ama":"Schäfer F, Trautmann A, Ngo C, et al.
