Our study examines the phase space representation of the system's eigenstates by comparing them to the classical phase space of a pendulum, to which the system effectively maps. The analysis reveals that quantum states can exhibit mixed dynamics by straddling the separatrix. A key finding is that the dynamics around the separatrix enables the controlled creation of highly nonclassical states, distinguishing them from the classical oscillatory or rotational dynamics of the pendulum. By considering a finite momentum of the initial wave packet, we demonstrate various dynamical regimes. Furthermore, a slight energy mismatch between nearly degenerate states localized at opposite turning points of the trap potential results in controlled long-range dynamical tunneling.

Harnessing the spectral correlations also permits refinement of the emission and unraveling of previously hidden strong correlations in a plethora of quantum-optical systems under continuous-wave excitation. In this work, we investigate such correlations for time-dependent excitation and develop a methodology to compute efficiently time-integrated correlations, which are at the heart of the photon-counting theory, and subsequently apply it to analyze the photon emission of pulsed systems. By combining this formalism with the —which facilitates frequency-resolved correlations—we demonstrate how spectral filtering enhances single-photon purity and suppresses multiphoton noise in time-bin-encoded quantum states. Specifically, filtering the central spectral peak of a dynamically driven two-level system boosts temporal coherence and improves the fidelity of time-bin entanglement preparation, even under conditions favoring multiphoton emission. These results establish spectral filtering as a critical tool for tailoring photon statistics in pulsed quantum light sources.</jats:p>","lang":"eng"}],"publication":"Physical Review Research","type":"journal_article"},{"publication_identifier":{"issn":["2643-1564"]},"publication_status":"published","issue":"3","year":"2025","intvolume":"         7","citation":{"bibtex":"@article{Kopylov_Stefszky_Meier_Silberhorn_Sharapova_2025, title={Spectral and temporal properties of type-II parametric down-conversion: The impact of losses during state generation}, volume={7}, DOI={<a href=\"https://doi.org/10.1103/zp72-7qwl\">10.1103/zp72-7qwl</a>}, number={3033122}, journal={Physical Review Research}, publisher={American Physical Society (APS)}, author={Kopylov, Denis A. and Stefszky, Michael and Meier, Torsten and Silberhorn, Christine and Sharapova, Polina R.}, year={2025} }","mla":"Kopylov, Denis A., et al. “Spectral and Temporal Properties of Type-II Parametric down-Conversion: The Impact of Losses during State Generation.” <i>Physical Review Research</i>, vol. 7, no. 3, 033122, American Physical Society (APS), 2025, doi:<a href=\"https://doi.org/10.1103/zp72-7qwl\">10.1103/zp72-7qwl</a>.","short":"D.A.

Using the example of frequency-degenerate type-II SPDC generated under the pump-idler group-velocity-matching condition, we show how the joint-spectral intensity, mode structure, normalized second-order correlation function, and Hong-Ou-Mandel interference pattern depend on internal losses of the SPDC process. We found that the joint-spectral intensity is almost insensitive to internal losses, while the second-order correlation function shows a strong dependence on them, being different for the signal and idler beams in the presence of internal losses. Based on the sensitivity of the normalized second-order correlation function, we show how its measurement can be used to experimentally determine internal losses.</jats:p>","lang":"eng"}],"status":"public","_id":"62911","project":[{"_id":"266","name":"PhoQC: Photonisches Quantencomputing"},{"name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen","_id":"53"},{"name":"TRR 142 - Project Area C","_id":"56"},{"_id":"174","name":"TRR 142 ; TP: C10: Erzeugung und Charakterisierung von Quantenlicht in nichtlinearen Systemen: Eine theoretische Analyse"}],"department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"293"},{"_id":"288"},{"_id":"230"},{"_id":"623"},{"_id":"429"},{"_id":"35"}],"user_id":"16199","article_number":"033122","language":[{"iso":"eng"}]},{"title":"Accelerating the analysis of optical quantum systems using the Koopman operator","doi":"10.1109/cdc56724.2024.10886589","date_updated":"2025-12-05T09:40:24Z","publisher":"IEEE","author":[{"id":"73659","full_name":"Hunstig, Anna","last_name":"Hunstig","first_name":"Anna"},{"first_name":"Sebastian","full_name":"Peitz, Sebastian","id":"47427","orcid":"0000-0002-3389-793X","last_name":"Peitz"},{"full_name":"Rose, Hendrik","id":"55958","orcid":"0000-0002-3079-5428","last_name":"Rose","first_name":"Hendrik"},{"first_name":"Torsten","full_name":"Meier, Torsten","id":"344","last_name":"Meier","orcid":"0000-0001-8864-2072"}],"date_created":"2025-12-05T09:37:58Z","year":"2025","citation":{"ama":"Hunstig A, Peitz S, Rose H, Meier T.

The comparably high mass of the muon (≈ 207 · <jats:italic>m<jats:sub>e</jats:sub>\r\n                  </jats:italic>) has two important effects, (i) the reduced mass of the system becomes more important, and (ii) the muon is localized much closer to the nucleus. Thus, muonic hydrogen is not only excellently suitable for evaluating highly precise quantum electrodynamic (QED) calculations, but may also be used for assessing new approaches including finite nuclear size (FNS) effects to evaluate the proton structure and improve calculation schemes for the hyperfine splittings of many-particle systems, as e.g. to be implemented in density functional theory (DFT) software packages. Here, starting from Dirac’s equation we calculate the relativistic hyperfine splitting of the ground state and several excited states of muonic hydrogen analytically for different charge and magnetization models. The FNS related hyperfine shifts are compared with the differences between QED calculations and experimental measurements. This comparison also allows to unravel the role of the reduced mass, which is on one hand crucial in case of muonic atoms, but on the other hand is by no means well defined in relativistic quantum mechanics.</jats:p>","lang":"eng"}],"status":"public","publication":"Journal of Physics: Conference Series","type":"journal_article","article_number":"012001","language":[{"iso":"eng"}],"_id":"61353","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"_id":"53","name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"},{"_id":"54","name":"TRR 142 - Project Area A"},{"name":"TRR 142 - Subproject A11","_id":"166"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"27"},{"_id":"790"}],"user_id":"16199","year":"2025","intvolume":"      3027","citation":{"apa":"Franzke, K.

The remarkable efficacy of n‐Butyl lithium (n‐BuLi) is highlighted in n‐doping C\r\n                    <jats:sub>60</jats:sub>\r\n                    and PC\r\n                    <jats:sub>61</jats:sub>\r\n                    BM, achieving a conductivity of 1.27 S cm\r\n                    <jats:sup>−1</jats:sup>\r\n                    and 2.57 S cm\r\n                    <jats:sup>−1</jats:sup>\r\n                    , respectively, which are among the highest reported values for these materials. The investigation reveals that the n‐BuLi anion interacts with electron‐deficient units in OSCs, generating a carbanion that facilitates efficient electron transfer for n‐doping. This mechanism is further validated across diverse fullerenes, polymeric, and small molecule OSCs, and is extendable to other high‐performance dopants such as tert‐Butyllithium (tert‐BuLi) and sodium ethoxide (NaOEt). Device studies show that n‐BuLi‐doped C\r\n                    <jats:sub>60</jats:sub>\r\n                    enables substantially improved diode rectification, attributed to greater junction built‐in potential. These findings establish a unified chemical‐bonding‐based n‐doping paradigm, complementing existing electrophilic‐attack p‐doping concepts, and pave the way for achieving efficient doping of OSCs for advanced organic electronic applications.\r\n                  </jats:p>","lang":"eng"}],"user_id":"16199","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"705"},{"_id":"35"},{"_id":"230"}],"_id":"62866","language":[{"iso":"eng"}],"article_number":"e20487","publication_status":"published","publication_identifier":{"issn":["2198-3844","2198-3844"]},"citation":{"ama":"Wei H, Wu T, Dong C, et al.

Going beyond isolated EPs, here we report on the existence of exceptional rings (ERs) in planar optical resonators with specific form of circular dichroism and TE-TM splitting. Such exceptional rings possess intriguing topologies as discussed earlier for condensed matter systems, but they remain virtually unexplored in presence of nonlinearity, for which our photonic platform is ideal. We find that when Kerr-type nonlinearity (or saturable gain) is introduced, the linear ER splits into two concentric ERs, with the larger-radius ring being a ring of third-order EPs. Transitioning from linear to nonlinear regime, we present a rigorous analysis of spectral topology and report enhanced and adjustable perturbation response in the nonlinear regime. Whereas certain features are specific to our system, the results on non-Hermitian spectral topology and nonlinearity-enhanced perturbation response are generic and equally relevant to a broad class of other nonlinear non-Hermitian systems, providing a universal framework for engineering ERs and EPs in nonlinear non-Hermitian systems.","lang":"eng"}],"type":"journal_article","publication":"Arxiv","language":[{"iso":"eng"}],"user_id":"16199","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"706"},{"_id":"705"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"27"}],"project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"_id":"53","name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"},{"name":"TRR 142 ; TP: C10: Erzeugung und Charakterisierung von Quantenlicht in nichtlinearen Systemen: Eine theoretische Analyse","_id":"174"},{"name":"TRR 142 - Project Area C","_id":"56"}],"_id":"60992","citation":{"apa":"Wingenbach, J., Ares Santos, L., Ma, X., Sperling, J., &#38; Schumacher, S.

However, quantifying the density of such defects in thin hBN flakes has remained elusive, limiting progress in device integration and reproducibility. Here, an all‐optical method is presented to quantify  defect density in hBN by correlating Raman and photoluminescence (PL) signatures with irradiation fluence. Two defect‐induced Raman modes, D1 and D2, are identified and assigned them to vibrational modes of  using polarization‐resolved Raman measurements and density functional theory (DFT) calculations. By adapting a numerical model originally developed for graphene, an empirical relationship linking Raman (D1,\r\n                    <jats:italic>E</jats:italic>\r\n                    <jats:sub>2g</jats:sub>\r\n                    ) and PL intensities is established to absolute defect densities.

The goal of providing or seeking explanations is to achieve (better) ‘understanding’ on the part of the explainee. However, what it means to ‘understand’ is still not clearly defined, and the concept itself is rarely the subject of scientific investigation. This conceptual article aims to present a model of forms of understanding for XAI-explanations and beyond. From an interdisciplinary perspective bringing together computer science, linguistics, sociology, philosophy and psychology, a definition of understanding and its forms, assessment, and dynamics during the process of giving everyday explanations are explored. Two types of understanding are considered as possible outcomes of explanations, namely enabledness, ‘knowing how’ to do or decide something, and comprehension, ‘knowing that’ – both in different degrees (from shallow to deep). Explanations regularly start with shallow understanding in a specific domain and can lead to deep comprehension and enabledness of the explanandum, which we see as a prerequisite for human users to gain agency. In this process, the increase of comprehension and enabledness are highly interdependent. Against the background of this systematization, special challenges of understanding in XAI are discussed."}],"file":[{"relation":"main_file","success":1,"content_type":"application/pdf","file_name":"Buschmeier-etal-2025-COGSYS.pdf","access_level":"closed","file_id":"62730","file_size":10114981,"date_created":"2025-12-01T21:02:20Z","creator":"hbuschme","date_updated":"2025-12-01T21:02:20Z"}]},{"status":"public","type":"journal_article","article_type":"original","_id":"61982","department":[{"_id":"985"}],"user_id":"116779","intvolume":"        15","page":"18391-18403","citation":{"bibtex":"@article{Kampermann_Klein_Wagner_Kotova_Placke-Yan_Yasar_Jacobse_Lasagna_Leppin_Schulz_et al._2025, title={Operando Analysis of the Pre-OER Activation of Metal-Doped Co<sub>3</sub>O<sub>4</sub> Nanoparticle Catalysts}, volume={15}, DOI={<a href=\"https://doi.org/10.1021/acscatal.5c03900\">10.1021/acscatal.5c03900</a>}, number={21}, journal={ACS Catalysis}, publisher={American Chemical Society (ACS)}, author={Kampermann, L. and Klein, J. and Wagner, T. and Kotova, A. and Placke-Yan, C. and Yasar, A. and Jacobse, L. and Lasagna, S. and Leppin, Christian and Schulz, S. and et al.}, year={2025}, pages={18391–18403} }","mla":"Kampermann, L., et al. “Operando Analysis of the Pre-OER Activation of Metal-Doped Co<sub>3</sub>O<sub>4</sub> Nanoparticle Catalysts.” <i>ACS Catalysis</i>, vol. 15, no. 21, American Chemical Society (ACS), 2025, pp. 18391–403, doi:<a href=\"https://doi.org/10.1021/acscatal.5c03900\">10.1021/acscatal.5c03900</a>.","short":"L.

In the low potential regime up to 1.37 VRHE, a rise in the optical absorption signal of the [Co3+]oct d–d transition is observed and attributed to a structural change from [Co2+]tet to [Co3+]oct due to an electrochemically induced surface restructuring with water. For applied potentials higher than 1.37 VRHE an overall offset of the absorption spectra in the UV–vis range, equivalent to a darkening of the materials is detected. This is attributed to the formation of a CoOx(OH)y skin layer as supported by high-energy X-ray diffraction (HE-XRD) measurements. We found that the kinetics of the Co3+ states are heavily influenced by the type of dopant with V-doped Co3O4 exhibiting stable Co3+ states (>20 min) while the Mn-doped Co3O4 Co3+ states reduce within 36 s under reductive bias. We conclude that doping Co3O4 with transition metals affects the formation and potential-dependent thickness of the CoOx(OH)y skin layer as the catalytically active phase and the formation of long-time stable surface Co3+ states after activation in the first OER cycle."}],"publication":"ACS Catalysis","keyword":["electrocatalysis","oxygen evolution reaction","cobalt spinel","operando characterization","spectroelectrochemistry"],"language":[{"iso":"eng"}],"year":"2025","quality_controlled":"1","issue":"21","title":"Operando Analysis of the Pre-OER Activation of Metal-Doped Co<sub>3</sub>O<sub>4</sub> Nanoparticle Catalysts","publisher":"American Chemical Society (ACS)","date_created":"2025-10-24T07:49:21Z"},{"publication":"STUDIA NEOFILOLOGICZ: NEROZPRAWY JĘZYKOZNAWCZE (Modern Language Studies: Linguistic Essays)","type":"journal_article","status":"public","abstract":[{"lang":"eng","text":"Many previous studies on the conceptual function of metaphors have focused on their func-tion  of  highlighting  aspects  of  target  concepts.

This study builds upon the idea that the hiding aspect of a specific metaphor should be identified in relation to other metaphors for the same concept. A method is presented to detail this relation based on the theory of semantic frames and the FrameNet resource to identify the hidden aspects and apply it to a corpus of 298 elicited metaphor texts on the target concept of understanding. The analysis revealed that certain conceptual aspects are consistently hidden by a majority of metaphors, pointing to patterns in conceptualization. Using  this  approach,  six  aspects  frequently  hidden  by  metaphors  were  identified:  Sociality, Transfer, Ownership, Perception, Foundation and Duration."}],"department":[{"_id":"424"}],"user_id":"451","_id":"62932","project":[{"_id":"127","name":"TRR 318; TP C04: Metaphern als Werkzeug des Erklärens"}],"language":[{"iso":"eng"}],"publication_status":"published","page":"181-198","citation":{"mla":"Porwol, Philip Fabian, and Ingrid Scharlau. “What Do Metaphors of Understanding Hide?” <i>STUDIA NEOFILOLOGICZ: NEROZPRAWY JĘZYKOZNAWCZE (Modern Language Studies: Linguistic Essays)</i>, vol.

The progressive etching of the PLA film in direct contact with the nitrogen plasma was monitored in situ using polarization modulated infrared reflection absorption spectroscopy (PM‐IRRAS). No appreciative changes in composition were seen with PM‐IRRAS, indicating that the etching did not significantly affect the bulk composition. Atomic force microscopy characterization of the plasma‐etched films showed that the PLA films are homogeneously etched. Subsequent ex situ XPS analysis of the treated surface revealed the presence of C‐N bonds in the surface‐near region that could be associated with amino and/or amide surface species. PLA films were also alternatively exposed to nitrogen ion beams produced by an electron‐cyclotron‐resonance (ECR) plasma source and were investigated in vacuo by XPS. This treatment revealed the partial substitution of surface oxygen species by nitrogen, resulting in a similar surface modification as in the plasma case. The comparison of XPS data and water contact angle studies suggest that the activated surfaces show a reorientation of macromolecular fragments in the surface‐near region depending on the polarity of the phase with which they are in contact. Under ultra‐high vacuum (UHV) conditions, the surface tends to lower its surface energy, while in contact with the aqueous phase, subsurface polar groups orientate outwards, which enables the formation of hydrogen bonds.</jats:p>","lang":"eng"}],"status":"public","publication":"Surface and Interface Analysis","type":"journal_article","language":[{"iso":"eng"}],"_id":"60913","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"department":[{"_id":"302"}],"user_id":"69524"},{"citation":{"ama":"Franke P, Schubert M, Hampel U, Kenig EY.

When operated under partially flooded conditions, they provide significant mass transfer improvement compared to common structured packings. In this work, a rate-based model including novel mass transfer correlations is presented and validated using a comprehensive experimental database for the reactive absorption of CO2 into aqueous monoethanolamine. The proposed rate-based approach is capable of accounting for axial dispersion, thereby enabling the evaluation of the effect of liquid-phase backmixing on the mass transfer performance. The validated rate-based model is used to evaluate the separation performance of sandwich packings. Compared with structured packings, up to 10 % higher mass transfer rates are obtained."}],"publication":"Chemical Engineering Science","keyword":["Sandwich packings Structured packings Rate-based approach Model validation Ultra-fast X-ray tomography"],"language":[{"iso":"eng"}]}]
