In this study, a variety of electron polarons, namely free, bound, and bipolarons, are analyzed using first-principles calculations. We perform a full structural optimization based on density-functional theory for selected intrinsic defects with special attention to the role of symmetry-breaking distortions that lower the total energy. The cations hosting the various polarons relax to a different degree, with a larger relaxation corresponding to a larger gap between the defect level and the conduction-band edge. The projected density of states reveals that the polaron states are formerly empty Nb 4d states lowered into the band gap. Optical absorption spectra are derived within the independent-particle approximation, corrected by the GW approximation that yields a wider band gap and by including excitonic effects within the Bethe-Salpeter equation. Comparing the calculated spectra with the density of states, we find that the defect peak observed in the optical absorption stems from transitions between the defect level and a continuum of empty Nb 4d states. Signatures of polarons are further analyzed in the reflectivity and other experimentally measurable optical coefficients.","lang":"eng"}],"publication":"New Trends in Lithium Niobate: From Bulk to Nanocrystals"},{"citation":{"mla":"Elsner, Julia, et al. “Modeling-Based Learning about Chemical Phenomena in Primary Education.” <i>Fostering Scientific Citizenship in an Uncertain World (Proceedings of ESERA 2021)</i>, edited by Graça S.

However, the material dispersion of integrated platforms constitutes an obstacle that limits the performance and precision of such interferometers. At the same time, two-colour nonlinear interferometers present an important tool for metrological applications, when measurements in a certain frequency range are difficult. In this manuscript, we theoretically developed and investigated an integrated multimode two-colour SU(1,1) interferometer operating in a supersensitive mode. By ensuring the proper design of the integrated platform, we suppressed the dispersion, thereby significantly increasing the visibility of the interference pattern. The use of a continuous wave pump laser provided the symmetry between the spectral shapes of the signal and idler photons concerning half the pump frequency, despite different photon colours. We demonstrate that such an interferometer overcomes the classical phase sensitivity limit for wide parametric gain ranges, when up to 3×104 photons are generated.</jats:p>"}],"status":"public","type":"journal_article","publication":"Symmetry","article_number":"552","keyword":["Physics and Astronomy (miscellaneous)","General Mathematics","Chemistry (miscellaneous)","Computer Science (miscellaneous)"],"language":[{"iso":"eng"}],"project":[{"_id":"53","name":"TRR 142: TRR 142"},{"name":"TRR 142 - C: TRR 142 - Project Area C","_id":"56"},{"_id":"72","name":"TRR 142 - C2: TRR 142 - Subproject C2"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"_id":"40371","user_id":"16199","department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"429"},{"_id":"230"},{"_id":"9"},{"_id":"27"}],"year":"2022","citation":{"chicago":"Ferreri, Alessandro, and Polina R.

To properly use these components in the implementation of different quantum protocols, photons with different properties are required. In this paper, we theoretically demonstrate a flexible source of correlated photons built on the LNOI waveguide of a special geometry. This source is based on the parametric down-conversion (PDC) process, in which the signal and idler photons are generated at the telecom wavelength and have different spatial profiles and polarizations, but the same group velocities. Distinguishability in polarizations and spatial profiles facilitates the routing and manipulating individual photons, while the equality of their group velocities leads to the absence of temporal walk-off between photons. We show how the spectral properties of the generated photons and the number of their frequency modes can be controlled depending on the pump characteristics and the waveguide length. Finally, we discuss special regimes, in which narrowband light with strong frequency correlations and polarization-entangled Bell states are generated at the telecom wavelength.","lang":"eng"}],"type":"journal_article","publication":"Journal of Physics: Photonics","doi":"10.1088/2515-7647/ac5a5b","title":"Flexible source of correlated photons based on LNOI rib waveguides","author":[{"last_name":"Ebers","id":"40428","full_name":"Ebers, Lena","first_name":"Lena"},{"last_name":"Ferreri","id":"65609","full_name":"Ferreri, Alessandro","first_name":"Alessandro"},{"last_name":"Hammer","orcid":"0000-0002-6331-9348","full_name":"Hammer, Manfred","id":"48077","first_name":"Manfred"},{"first_name":"Maximilian","full_name":"Albert, Maximilian","last_name":"Albert"},{"last_name":"Meier","orcid":"https://orcid.org/0000-0002-3787-3572","id":"20798","full_name":"Meier, Cedrik","first_name":"Cedrik"},{"orcid":"0000-0001-7059-9862","last_name":"Förstner","id":"158","full_name":"Förstner, Jens","first_name":"Jens"},{"full_name":"Sharapova, Polina R.","id":"60286","last_name":"Sharapova","first_name":"Polina R."}],"date_created":"2022-03-07T09:51:50Z","volume":4,"date_updated":"2025-12-16T11:31:04Z","publisher":"IOP Publishing","citation":{"short":"L.

In the present study, conventional hot-rolled (HR) pure iron is compared to pure iron manufactured by electron beam melting (EBM). The microstructure, the corrosion behavior and the fatigue properties were studied comprehensively. The investigated sample conditions showed significant differences in the microstructures that led to changes in corrosion and fatigue properties.

In this contribution, the notion of a driven Gaussian quantum walk is introduced. In contrast to typically considered quantum walks in optical settings, we describe the operation of the walk in terms of a nonlinear map rather than a unitary operation, e.g., by replacing a beam-splitter-type coin with a two-mode squeezer, being a process that is controlled and driven by a pump field. This opens previously unattainable possibilities for quantum walks that include nonlinear elements as core components of their operation, vastly extending their range of applications. A full framework for driven Gaussian quantum walks is developed, including methods to dynamically characterize nonlinear, quantum, and quantum-nonlinear effects. Moreover, driven Gaussian quantum walks are compared with their classically interfering and linear counterparts, which are based on classical coherence of light rather than quantum superpositions. In particular, the generation and boost of highly multimode entanglement, squeezing, and other quantum effects are studied over the duration of the nonlinear walk. Importantly, we prove the quantumness of the evolution itself, regardless of the input state. A scheme for an experimental realization is proposed. Furthermore, nonlinear properties of driven Gaussian quantum walks are explored, such as amplification that leads to an ever increasing number of correlated quantum particles, constituting a source of new walkers during the walk. Therefore, a concept for quantum walks is proposed that leads to—and even produces—directly accessible quantum phenomena, and that renders the quantum simulation of nonlinear processes possible.","lang":"eng"}],"publication":"Physical Review A","language":[{"iso":"eng"}]},{"title":"2050 - The Future Podcast, Folge Smarte Energien für die Zukunft","date_updated":"2026-03-10T12:36:50Z","publisher":"Marcus Nettelbeck","author":[{"last_name":"Schlüter","orcid":"0000-0002-2569-1624","full_name":"Schlüter, Alexander","id":"103302","first_name":"Alexander"}],"date_created":"2024-03-10T08:08:57Z","year":"2022","citation":{"apa":"Schlüter, A.

Lehramtsstudierende im Praxissemester waren verstärkt mit vollständigen Schließungen und Unterricht auf Distanz konfrontiert. Auch wenn teilweise Öffnungen stattfanden, waren das Ausmaß und die Art von schulischen Lerngelegenheiten anders als unter Bedingungen typischer Praxissemester. Universitäre Begleitveranstaltungen fanden ebenfalls überwiegend auf Distanz statt. Solche Situationen der Ungewissheit und schnelle Adaptionen an veränderte Rahmenbedingungen können zu verstärktem Stress führen. Um zu untersuchen, inwiefern sich die Bedingungen des Praxissemesters während des Lockdowns im Frühjahr 2020 auf das Belastungserleben der Studierenden ausgewirkt haben, wurde eine Vergleichsanalyse zweier repräsentativer Praxissemesterkohorten der Universität Paderborn vorgenommen. Als Teil regelmäßiger Onlinebefragungen wurde das Belastungserleben der Studierenden der COVID-19-beeinflussten Kohorte (N1=344) und der vorherigen Kohorte unter typischen Bedingungen (N2=268) sowohl zu Beginn als auch am Ende des Praxissemesters mit Hilfe des Maslach-Burnout- Inventars für Studierende erhoben. Die Ergebnisse zeigen, dass die emotionale Erschöpfung im Verlauf des COVID-19-beeinflussten Praxissemesters geringer wurde. Zudem war das Erleben emotionaler Erschöpfung im Praxissemester während der Schulschließungen geringer als im typischen Praxissemester. Die Unterstützung durch Praxismentor*innen konnte als wichtiger Einflussfaktor bestätigt werden. Als subjektiv bedeutsamsten Belastungsfaktor im COVID-19-Semester nannten die Studierenden die Wahrnehmung von Ungewissheit bzgl. ihrer professionellen Entwicklung.","lang":"eng"}],"status":"public","date_updated":"2023-01-09T15:22:07Z","date_created":"2021-10-05T08:22:07Z","author":[{"id":"4245","full_name":"Vogelsang, Christoph","last_name":"Vogelsang","first_name":"Christoph"}],"title":"Wie belastend war das Corona-Semester?
