The fabrication of low-loss optical waveguides, as well as high-grade periodically poled ferroelectric domain structures, requires a profound understanding of the material properties and crystal structure. In this regard, Raman spectroscopy offers the possibility to study and visualize domain structures, strain, defects, and the local stoichiometry, which are all factors impacting device performance. However, the accurate interpretation of Raman spectra and their changes with respect to extrinsic and intrinsic defects requires a thorough assignment of the Raman modes to their respective crystal features, which to date is only partly conducted based on phenomenological modelling. To address this issue, we calculated the phonon spectra of potassium titanyl phosphate and the related compounds rubidium titanyl phosphate (RbTiOPO4) and potassium titanyl arsenate (KTiOAsO4) based on density functional theory and compared them with experimental data. Overall, this allows us to assign various spectral features to eigenmodes of lattice substructures with improved detail compared to previous assignments. Nevertheless, the analysis also shows that not all features of the spectra can unambigiously be explained yet. A possible explanation might be that defects or long range fields not included in the modeling play a crucial rule for the resulting Raman spectrum. In conclusion, this work provides an improved foundation into the vibrational properties in the KTiOPO4 material family.","lang":"eng"}],"publication":"Crystals","issue":"10","department":[{"_id":"169"}],"keyword":["Inorganic Chemistry","Condensed Matter Physics","General Materials Science","General Chemical Engineering"],"type":"journal_article","date_created":"2023-10-11T09:10:53Z","intvolume":" 13","publication_status":"published","date_updated":"2023-10-11T09:15:58Z","author":[{"full_name":"Neufeld, Sergej","last_name":"Neufeld","first_name":"Sergej"},{"full_name":"Gerstmann, Uwe","last_name":"Gerstmann","orcid":"0000-0002-4476-223X","first_name":"Uwe","id":"171"},{"id":"40300","last_name":"Padberg","first_name":"Laura","full_name":"Padberg, Laura"},{"id":"13244","last_name":"Eigner","orcid":"https://orcid.org/0000-0002-5693-3083","first_name":"Christof","full_name":"Eigner, Christof"},{"last_name":"Berth","first_name":"Gerhard","full_name":"Berth, Gerhard","id":"53"},{"last_name":"Silberhorn","first_name":"Christine","full_name":"Silberhorn, Christine","id":"26263"},{"last_name":"Eng","first_name":"Lukas M.","full_name":"Eng, Lukas M."},{"id":"468","last_name":"Schmidt","orcid":"0000-0002-2717-5076","first_name":"Wolf Gero","full_name":"Schmidt, Wolf Gero"},{"id":"22501","full_name":"Rüsing, Michael","last_name":"Rüsing","orcid":"0000-0003-4682-4577","first_name":"Michael"}],"publication_identifier":{"issn":["2073-4352"]},"title":"Vibrational Properties of the Potassium Titanyl Phosphate Crystal Family","year":"2023","doi":"10.3390/cryst13101423","language":[{"iso":"eng"}],"article_number":"1423","main_file_link":[{"open_access":"1","url":"https://doi.org/10.3390/cryst13101423"}]},{"quality_controlled":"1","citation":{"mla":"Bashir, Umar, et al. “Solid Solutions of Lithium Niobate and Lithium Tantalate: Crystal Growth and the Ferroelectric Transition.” Ferroelectrics, vol. 613, no. 1, Informa UK Limited, 2023, pp. 250–62, doi:10.1080/00150193.2023.2189842.","ama":"Bashir U, Böttcher K, Klimm D, 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.","lang":"eng"}],"issue":"2","publication":"PAMM","doi":"10.1002/pamm.202300071","language":[{"iso":"eng"}],"intvolume":" 23","date_updated":"2023-11-07T14:34:44Z","publication_status":"published","author":[{"last_name":"Westermann","first_name":"Hendrik","orcid":"0000-0002-5034-9708","full_name":"Westermann, Hendrik","id":"60816"},{"id":"335","last_name":"Mahnken","first_name":"Rolf","full_name":"Mahnken, Rolf"}],"publication_identifier":{"issn":["1617-7061","1617-7061"]},"year":"2023","title":"Numerical investigations of new low‐order explicit last stage diagonal implicit Runge–Kutta schemes with the finite‐element method"},{"_id":"48465","publisher":"Elsevier BV","user_id":"335","volume":418,"status":"public","citation":{"mla":"Westermann, Hendrik, and Rolf Mahnken. “On the Accuracy, Stability and Computational Efficiency of Explicit Last-Stage Diagonally Implicit Runge–Kutta Methods (ELDIRK) for the Adaptive Solution of Phase-Field Problems.” Computer Methods in Applied Mechanics and Engineering, vol. 418, 116545, Elsevier BV, 2023, doi:10.1016/j.cma.2023.116545.","ama":"Westermann H, Mahnken R.

To mitigate the narrowing of coronary artery atherosclerosis (stenosis), the computational modelling of auxetic and non-auxetic stents was performed in this study to minimise or even avoid these deposition agents in the future. Computational modelling was performed in unrestricted (open) conditions and restricted (in an artery) conditions. Finally, stent designs were produced by additive manufacturing, and mechanical testing of the stents was undertaken. Auxetic stent 1 and auxetic stent 2 exhibit very little foreshortening and radial recoil in unrestricted deployment conditions compared to non-auxetic stent 3. However, stent 2 shows structural instability (strut failure) during unrestricted deployment conditions. For the restricted deployment condition, stent 1 shows a higher radial recoil compared to stent 3. In the tensile test simulations, short elongation for stent 1 due to strut failure is demonstrated, whereas no structural instability is noticed for stent 2 and stent 3 until 0.5 (mm/mm) strain. The as-built samples show a significant thickening of the struts of the stents resulting in short elongations during tensile testing compared to the simulations (stent 2 and stent 3). A modelling framework for the stent deployment system that enables the selection of appropriate stent designs before in vivo testing is required. This leads to the acceleration of the development process and a reduction in time, resulting in less material wastage. The modelling framework shall be useful for doctors designing patient-specific stents."}],"publication":"Crystals","issue":"11","user_id":"48411","volume":13,"publisher":"MDPI AG","_id":"49107","status":"public","quality_controlled":"1","citation":{"chicago":"Pramanik, Sudipta, Dennis Milaege, Maxwell Hein, Kay-Peter Hoyer, and Mirko Schaper. “Additive Manufacturing and Mechanical Properties of Auxetic and Non-Auxetic Ti24Nb4Zr8Sn Biomedical Stents: A Combined Experimental and Computational Modelling Approach.” Crystals 13, no. 11 (2023). https://doi.org/10.3390/cryst13111592.","short":"S.

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.","lang":"eng"}],"_id":"49866","publisher":"Wiley","language":[{"iso":"eng"}],"doi":"10.1002/pamm.202300136","user_id":"335","status":"public","year":"2023","title":"Downwind and upwind approximations for mesh and model adaptivity of elasto‐plastic composites","author":[{"id":"83075","full_name":"Tchomgue Simeu, Arnold","last_name":"Tchomgue Simeu","first_name":"Arnold"},{"id":"335","full_name":"Mahnken, Rolf","first_name":"Rolf","last_name":"Mahnken"}],"publication_identifier":{"issn":["1617-7061","1617-7061"]},"date_updated":"2023-12-19T12:20:51Z","publication_status":"published"},{"abstract":[{"text":"In the last decade, conductive domain walls (CDWs) in single crystals of the uniaxial model ferroelectric lithium niobate (LiNbO3; LNO) have been shown to reach resistances more than 10 orders of magnitude lower than the resistance of the surrounding bulk, with charge carriers being firmly confined to sheets with a width of a few nanometers. LNO is thus currently witnessing increased attention because of its potential in the design of room-temperature nanoelectronic circuits and devices based on such CDWs. In this context, the reliable determination of the fundamental transport parameters of LNO CDWs, in particular the 2D charge carrier density n2D and the Hall mobility μH of the majority carriers, is of great interest. In this contribution, we present and apply a robust and easy-to-prepare Hall-effect measurement setup by adapting the standard four-probe van der Pauw method to contact a single, hexagonally shaped domain wall that fully penetrates the 200-μm-thick LNO bulk single crystal. We then determine n2D and μH for a set of external magnetic fields B and prove the expected cosinelike angular dependence of the Hall voltage. Lastly, we present photoinduced-Hall-effect measurements of one and the same DW, by determining the impact of super-band-gap illumination on n2D.","lang":"eng"}],"publication":"Physical Review Applied","issue":"6","keyword":["General Physics and Astronomy"],"type":"journal_article","date_created":"2024-01-09T15:03:22Z","intvolume":" 20","article_type":"original","date_updated":"2024-01-09T15:05:29Z","publication_status":"published","publication_identifier":{"issn":["2331-7019"]},"author":[{"full_name":"Beccard, Henrik","first_name":"Henrik","last_name":"Beccard"},{"last_name":"Beyreuther","first_name":"Elke","full_name":"Beyreuther, Elke"},{"full_name":"Kirbus, Benjamin","first_name":"Benjamin","last_name":"Kirbus"},{"first_name":"Samuel D.","last_name":"Seddon","full_name":"Seddon, Samuel D."},{"orcid":"0000-0003-4682-4577","last_name":"Rüsing","first_name":"Michael","full_name":"Rüsing, Michael","id":"22501"},{"full_name":"Eng, Lukas M.","last_name":"Eng","first_name":"Lukas M."}],"year":"2023","title":"Hall mobilities and sheet carrier densities in a single LiNbO3 conductive ferroelectric domain wall","doi":"10.1103/physrevapplied.20.064043","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://arxiv.org/pdf/2308.00061.pdf","open_access":"1"}],"article_number":"064043","citation":{"bibtex":"@article{Beccard_Beyreuther_Kirbus_Seddon_Rüsing_Eng_2023, title={Hall mobilities and sheet carrier densities in a single LiNbO3 conductive ferroelectric domain wall}, volume={20}, DOI={10.1103/physrevapplied.20.064043}, number={6064043}, journal={Physical Review Applied}, publisher={American Physical Society (APS)}, author={Beccard, Henrik and Beyreuther, Elke and Kirbus, Benjamin and Seddon, Samuel D. and Rüsing, Michael and Eng, Lukas M.}, year={2023} }","ama":"Beccard H, Beyreuther E, Kirbus B, Seddon SD, Rüsing M, Eng LM.

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."}],"citation":{"chicago":"Börger, Alexander, and Rolf Mahnken. “A Micropolar Model Accounting for Asymmetric Behavior of Cold‐box Sand in Relation to Tensile and Compression Tests.” PAMM, 2023. https://doi.org/10.1002/pamm.202300126.","short":"A.
