Besides the original parameter sets, some specifically reparametrized SQC methods (denoted as AM1-W, PM6-fm, and DFTB2-iBi) targeting various smaller water systems ranging from molecular clusters to bulk are considered as well. The quality of these different SQC methods for describing liquid water properties at ambient conditions are assessed by comparison to well-established experimental data and also to BLYP-D3 density functional theory-based ab initio MD simulations. Our analyses reveal that static and dynamics properties of bulk water are poorly described by all considered SQC methods with the original parameters, regardless of the underlying theoretical models, with most of the methods suffering from too weak hydrogen bonds and hence predicting a far too fluid water with highly distorted hydrogen bond kinetics. On the other hand, the reparametrized force-matchcd PM6-fm method is shown to be able to quantitatively reproduce the static and dynamic features of liquid water, and thus can be used as a computationally efficient alternative to electronic structure-based MD simulations for liquid water that requires extended length and time scales. DFTB2-iBi predicts a slightly overstructured water with reduced fluidity, whereas AM1-W gives an amorphous ice-like structure for water at ambient conditions."}],"citation":{"ieee":"X.

Meanwhile, the existing methods of its characterization are technically complicated, which reduces the level of squeezing, and mostly deal with a single mode at a time. Here, for the first time, to the best of our knowledge, we employ optical parametric amplification to characterize multiple squeezing eigenmodes simultaneously. We retrieve the shapes and squeezing degrees of all modes at once through direct detection followed by modal decomposition. This method is tolerant to inefficient detection and does not require a local oscillator. For a spectrally and spatially multimode squeezed vacuum, we characterize eight strongest spatial modes, obtaining squeezing and anti-squeezing values of up to −5.2 ± 0.2 dB and 8.6 ± 0.3 dB, respectively, despite the 50% detection loss. This work, being the first exploration of an optical parametric amplifier’s multimode capability for squeezing detection, paves the way for the real-time detection of multimode squeezing.","lang":"eng"}],"language":[{"iso":"eng"}],"article_number":"36","main_file_link":[{"open_access":"1","url":"https://opg.optica.org/opticaq/viewmedia.cfm?uri=opticaq-3-1-36&seq=0"}],"doi":"10.1364/opticaq.524682","author":[{"full_name":"Barakat, Ismail","last_name":"Barakat","first_name":"Ismail"},{"full_name":"Kalash, Mahmoud","last_name":"Kalash","first_name":"Mahmoud"},{"first_name":"Dennis","last_name":"Scharwald","orcid":"0009-0007-5654-5412","full_name":"Scharwald, Dennis","id":"55907"},{"first_name":"Polina","last_name":"Sharapova","full_name":"Sharapova, Polina","id":"60286"},{"first_name":"Norbert","last_name":"Lindlein","full_name":"Lindlein, Norbert"},{"first_name":"Maria","last_name":"Chekhova","full_name":"Chekhova, Maria"}],"publication_identifier":{"issn":["2837-6714"]},"year":"2025","title":"Simultaneous measurement of multimode squeezing through multimode phase-sensitive amplification","article_type":"original","intvolume":"         3","publication_status":"published","date_updated":"2026-02-10T22:44:44Z","oa":"1","citation":{"ieee":"I.

This split allows us to avoid higher-order time integration schemes, to apply a first-order explicit time stepping for the remaining nonlinear NLSE term in a variational algorithm block, and thus to avoid numerical instabilities. We demonstrate that the analytical solution is reproduced with a small root mean square error for a long time interval over which a nonlinear soliton propagates significantly forward in space while keeping its shape.

DWs show very different properties as compared to their hosting bulk crystal, in particular with respect to the high local electrical conductivity. The objective of this work is to demonstrate DW conductivity up to temperatures as high as 400 °C which extends previous studies significantly. Experimental investigation of the DW conductivity of charged, inclined DWs is performed using 5 mol % MgO-doped lithium niobate single crystals. Current–voltage (  ) curves are determined by DC electrometer measurements and impedance spectroscopy and found to be identical. Moreover, impedance spectroscopy enables to recognize artifacts such as damaged electrodes. Temperature dependent measurements over repeated heating cycles reveal two distinct thermal activation energies for a given DW, with the higher of the activation energies only measured at higher temperatures. Depending on the specific sample, the higher activation energy is found above 160 °C to 230 °C. This suggests, in turn, that more than one type of defect/polaron is involved, and that the dominant transport mechanism changes with increasing temperature. First principles atomistic modeling suggests that the conductivity of inclined domain walls cannot be solely explained by the formation of a 2D carrier gas and must be supported by hopping processes. This holds true even at temperatures as high as 400 °C. Our investigations underline the potential to extend DW current based nanoelectronic and sensor applications even into the so-far unexplored temperature range up to 400 °C."}],"publication":"Solid State Ionics","type":"journal_article","department":[{"_id":"15"},{"_id":"288"},{"_id":"623"}],"date_created":"2025-09-17T16:18:18Z"},{"oa":"1","quality_controlled":"1","citation":{"apa":"Koppitz, B., Saxena, T., Bernhardt, F., Ganschow, S., Sanna, S., Rüsing, M., &#38; Eng, L.

In this work, we demonstrate how ferroelectric domain walls can unambiguously be identified and distinguished from local changes in composition by correlating piezoresponse force microscopy with second harmonic generation microscopy, using the Cherenkov contrast, reference crystal contrast, and negative phase mismatching contrast. We demonstrate how measuring the associated intensity change when approaching negative phase mismatching can be used to deduce the local tantalum concentration fast and over a large sample area. Based on these results, we study the natural domain structures that appear from Czochralski-grown, multi-domain LNT solid solution crystals.

Despite advances in fundamental understanding of water‐exposed surfaces, the detailed time‐ and energy‐resolved behavior of excited electrons remains largely unexplored. Here, the effects of water exposure on the near‐surface electron dynamics of phosphorus‐terminated p(2×2)/c(4×2)‐reconstructed indium phosphide (100) (P‐rich InP) are studied experimentally and matched to theoretical calculations. The P‐rich InP surface, consisting of H‐passivated P‐dimers, serves as a model for other P‐containing III‐V semiconductors such as gallium phosphide (GaP) or aluminum indium phosphide (AlInP). Electron dynamics near the surface are probed with femtosecond resolution using time‐resolved two‐photon photoemission (tr‐2PPE), a pump‐probe spectroscopic technique. Pulsed water exposure preserves electronic states and significantly increases lifetimes at the conduction band minimum (CBM). Density‐functional theory (DFT) calculations attribute these findings to suppression of surface vibrational modes in the top P‐layer by water exposure, reducing electronic transition probabilities of near‐band‐gap surface states. The results suggest that many near‐surface state lifetimes reported in ultra‐high vacuum may change significantly upon electrolyte exposure. These states may thus contribute more strongly to surface reactions than traditionally assumed. Demonstrating this effect for the technologically relevant P‐rich InP surface opens new opportunities in this underexplored area of surface electrochemistry.</jats:p>"}],"issue":"16","publication":"Advanced Materials Interfaces","department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"35"},{"_id":"230"},{"_id":"27"},{"_id":"429"}],"type":"journal_article","date_created":"2025-09-18T11:03:16Z","intvolume":"        12","publication_status":"published","date_updated":"2025-09-18T11:06:59Z","author":[{"last_name":"Diederich","first_name":"Jonathan","full_name":"Diederich, Jonathan"},{"first_name":"Agnieszka","last_name":"Paszuk","full_name":"Paszuk, Agnieszka"},{"orcid":"0000-0002-4710-1170","last_name":"Ruiz Alvarado","first_name":"Isaac Azahel","full_name":"Ruiz Alvarado, Isaac Azahel","id":"79462"},{"full_name":"Krenz, Marvin","first_name":"Marvin","last_name":"Krenz"},{"full_name":"Zare Pour, Mohammad Amin","first_name":"Mohammad Amin","last_name":"Zare Pour"},{"first_name":"Diwakar Suresh","last_name":"Babu","full_name":"Babu, Diwakar Suresh"},{"full_name":"Velazquez Rojas, Jennifer","first_name":"Jennifer","last_name":"Velazquez Rojas"},{"full_name":"Höhn, Christian","last_name":"Höhn","first_name":"Christian"},{"last_name":"Gao","first_name":"Yuying","full_name":"Gao, Yuying"},{"first_name":"Klaus","last_name":"Schwarzburg","full_name":"Schwarzburg, Klaus"},{"first_name":"David","last_name":"Ostheimer","full_name":"Ostheimer, David"},{"last_name":"Eichberger","first_name":"Rainer","full_name":"Eichberger, Rainer"},{"orcid":"0000-0002-2717-5076","first_name":"Wolf Gero","last_name":"Schmidt","full_name":"Schmidt, Wolf Gero","id":"468"},{"full_name":"Hannappel, Thomas","last_name":"Hannappel","first_name":"Thomas"},{"last_name":"de Krol","first_name":"Roel van","full_name":"de Krol, Roel van"},{"full_name":"Friedrich, Dennis","first_name":"Dennis","last_name":"Friedrich"}],"publication_identifier":{"issn":["2196-7350","2196-7350"]},"year":"2025","title":"Ultrafast Electron Dynamics at the Water‐Modified InP(100) Surface","doi":"10.1002/admi.202500463","language":[{"iso":"eng"}],"article_number":"e00463","project":[{"_id":"53","name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"},{"_id":"55","name":"TRR 142 - Project Area B"},{"_id":"168","name":"TRR 142 - Polaronen-Einfluss auf die optischen Eigenschaften von Lithiumniobat (B07*)"},{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"citation":{"short":"J.

This approach is valid for Markovian environments and includes both a model of discrete losses based on the beamsplitter approach and a generalized continuous loss model based on the spatial Langevin equation. For an important class of Gaussian states, we derive master equations for the second-order correlation functions and illustrate their solution for both frequency-independent and frequency-dependent losses. Studying the mode structure, we demonstrate that in a lossy environment no broadband basis without quadrature correlations between the different broadband modes exists. Therefore, various techniques and strategies to introduce broadband modes can be considered. We show that the Mercer expansion and the Williamson-Euler decomposition do not provide modes in which the maximal squeezing contained in the system can be measured. In turn, we find a new broadband basis that maximizes squeezing in the lossy system and present an algorithm to construct it.</jats:p>","lang":"eng"}],"publication":"Quantum","type":"journal_article","department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"293"},{"_id":"35"},{"_id":"230"},{"_id":"623"},{"_id":"27"}],"date_created":"2025-02-05T12:57:37Z","status":"public","user_id":"16199","volume":9,"publisher":"Verein zur Forderung des Open Access Publizierens in den Quantenwissenschaften","_id":"58519","project":[{"_id":"266","name":"PhoQC: PhoQC: Photonisches Quantencomputing"},{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"citation":{"ama":"Kopylov DA, Meier T, Sharapova PR.

Despite the enormous advances of ab initio simulations in materials science, quantitative calculations of spin-wave spectra still pose a significant challenge, because the collective nature of the spin dynamics requires an accurate treatment of the Coulomb interaction between the electrons. As a consequence, simple lattice models like the Heisenberg Hamiltonian are still widespread in practical investigations, but modern techniques like time-dependent density-functional theory or many-body perturbation theory also open a route to material-specific spin-wave calculations from first principles. Although both are in principle exact, actual implementations necessarily employ approximations for electronic exchange and correlation as well as additional numerical simplifications. In this review, we recapitulate the theoretical foundations of ab initio spin-wave calculations and analyze the common approximations that underlie present implementations. In addition, we survey the available results for spin-wave dispersions of various magnetic materials and compare the performance of different computational approaches. In this way, we provide an overview of the present state of the art and identify directions for further developments.","lang":"eng"}],"issue":"18","publication":"Materials","doi":"10.3390/ma18184431","language":[{"iso":"eng"}],"article_number":"4431","intvolume":"        18","article_type":"review","date_updated":"2025-10-10T07:31:23Z","publication_status":"published","publication_identifier":{"eissn":["1996-1944"]},"author":[{"id":"80813","first_name":"Michael","last_name":"Neugum","full_name":"Neugum, Michael"},{"id":"458","full_name":"Schindlmayr, Arno","orcid":"0000-0002-4855-071X","first_name":"Arno","last_name":"Schindlmayr"}],"title":"Ab initio calculations of spin waves: A review of theoretical approaches and applications","year":"2025","oa":"1","external_id":{"isi":["001580599300001"]},"quality_controlled":"1","citation":{"ama":"Neugum M, Schindlmayr A.

It is now accepted as a useful tool for guiding experiments and computational materials discovery, but its theoretical foundation had long been limited to a derivation for the classical Lorentz model with a weak anharmonic perturbation. Recently, we developed a mathematical framework which enabled us to prove that Miller's rule is equally valid for quantum anharmonic oscillators, despite different dynamics due to zero-point fluctuations and further quantum-mechanical effects. However, our previous derivation applied only to one-dimensional oscillators and to the special case of second- and third-harmonic generation in a monochromatic electric field. Here we extend the proof to three-dimensional quantum anharmonic oscillators and also treat all orders of the nonlinear response to an arbitrary multi-frequency field. This makes the results applicable to a much larger range of physical systems and nonlinear optical processes. The obtained generalized Miller formulae rigorously express all tensor elements of the frequency-dependent nonlinear susceptibilities in terms of the linear susceptibility and thus allow a computationally inexpensive quantitative prediction of arbitrary parametric frequency-mixing processes from a small initial dataset.","lang":"eng"}],"issue":"3","publication":"Dynamics","department":[{"_id":"296"},{"_id":"230"},{"_id":"15"},{"_id":"170"},{"_id":"35"}],"type":"journal_article","date_created":"2025-08-20T09:46:13Z","file":[{"date_created":"2025-08-28T12:23:26Z","description":"Creative Commons Attribution 4.0 International Public License (CC BY 4.0)","creator":"schindlm","content_type":"application/pdf","file_id":"61056","title":"Generalized Miller formulae for quantum anharmonic oscillators","access_level":"open_access","file_size":375897,"file_name":"dynamics-05-00034.pdf","date_updated":"2025-08-28T12:27:05Z","relation":"main_file"}]},{"abstract":[{"lang":"eng","text":"<jats:title>Abstract</jats:title><jats:p>Controlling the surface orientation of DNA origami nanostructures (DON) is crucial for applications in nanotechnology and materials science.
