We find three principal configurations of hole polarons: (i) self-trapped holes localized at displaced regular oxygen atoms and (ii) two other configurations bound to a lithium vacancy either at a threefold coordinated oxygen atom above or at a two-fold coordinated oxygen atom below the defect. The latter is the most stable and is in excellent quantitative agreement with measured g factors from electron paramagnetic resonance. Due to the absence of mid-gap states, none of these hole polarons can explain the broad optical absorption centered between 2.5 and 2.8 eV that is observed in transient absorption spectroscopy, but such states appear if a free electron polaron is trapped at the same lithium vacancy as the bound hole polaron, resulting in an exciton polaron. The dielectric function calculated by solving the Bethe–Salpeter equation indeed yields an optical peak at 2.6 eV in agreement with the two-photon experiments. The coexistence of hole and exciton polarons, which are simultaneously created in optical excitations, thus satisfactorily explains the reported experimental data.","lang":"eng"}],"article_number":"1586","language":[{"iso":"eng"}],"doi":"10.3390/cryst12111586","title":"A density-functional theory study of hole and defect-bound exciton polarons in lithium niobate","year":"2022","publication_identifier":{"eissn":["2073-4352"]},"author":[{"last_name":"Schmidt","orcid":"0000-0002-5071-5528","first_name":"Falko","full_name":"Schmidt, Falko","id":"35251"},{"id":"77566","orcid":"0000-0001-6584-0201","last_name":"Kozub","first_name":"Agnieszka L.","full_name":"Kozub, Agnieszka L."},{"id":"171","last_name":"Gerstmann","first_name":"Uwe","orcid":"0000-0002-4476-223X","full_name":"Gerstmann, Uwe"},{"id":"468","full_name":"Schmidt, Wolf Gero","first_name":"Wolf Gero","last_name":"Schmidt","orcid":"0000-0002-2717-5076"},{"first_name":"Arno","orcid":"0000-0002-4855-071X","last_name":"Schindlmayr","full_name":"Schindlmayr, Arno","id":"458"}],"date_updated":"2025-09-18T13:28:05Z","publication_status":"published","intvolume":"        12","article_type":"original"},{"_id":"34094","publisher":"AIP Publishing","user_id":"16199","volume":121,"status":"public","citation":{"ama":"Gao Y, Li Y, Ma X, et al.

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."}],"publication":"New Trends in Lithium Niobate: From Bulk to Nanocrystals","department":[{"_id":"296"},{"_id":"230"},{"_id":"429"},{"_id":"295"},{"_id":"15"},{"_id":"170"},{"_id":"35"},{"_id":"790"}],"type":"book_chapter","date_created":"2022-03-13T15:28:47Z","status":"public","editor":[{"last_name":"Corradi","first_name":"Gábor","full_name":"Corradi, Gábor"},{"first_name":"László","last_name":"Kovács","full_name":"Kovács, László"}],"ddc":["530"],"user_id":"16199","_id":"30288","publisher":"MDPI","page":"231-248","project":[{"name":"TRR 142: TRR 142","_id":"53"},{"_id":"55","name":"TRR 142 - B: TRR 142 - Project Area B"},{"_id":"69","name":"TRR 142 - B4: TRR 142 - Subproject B4"},{"name":"TRR 142 - A: TRR 142 - Project Area A","_id":"54"},{"_id":"166","name":"TRR 142 - A11: TRR 142 - Subproject A11"},{"name":"TRR 142 - B07: TRR 142 - Subproject B07","_id":"168"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"_id":"53","name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"}],"quality_controlled":"1","citation":{"ama":"Schmidt F, Kozub AL, Gerstmann U, Schmidt WG, Schindlmayr A.

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.

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.

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"}],"date_created":"2022-04-20T06:38:07Z","department":[{"_id":"623"},{"_id":"15"},{"_id":"170"},{"_id":"706"},{"_id":"288"},{"_id":"230"},{"_id":"429"},{"_id":"35"}],"type":"journal_article","author":[{"id":"68236","first_name":"Philip","last_name":"Held","full_name":"Held, Philip"},{"full_name":"Engelkemeier, Melanie","last_name":"Engelkemeier","first_name":"Melanie"},{"full_name":"De, Syamsundar","first_name":"Syamsundar","last_name":"De"},{"id":"48188","full_name":"Barkhofen, Sonja","last_name":"Barkhofen","first_name":"Sonja"},{"id":"75127","full_name":"Sperling, Jan","first_name":"Jan","orcid":"0000-0002-5844-3205","last_name":"Sperling"},{"id":"26263","full_name":"Silberhorn, Christine","last_name":"Silberhorn","first_name":"Christine"}],"publication_identifier":{"issn":["2469-9926","2469-9934"]},"year":"2022","title":"Driven Gaussian quantum walks","article_type":"original","intvolume":"       105","publication_status":"published","date_updated":"2026-01-09T09:50:22Z","language":[{"iso":"eng"}],"article_number":"042210","main_file_link":[{"url":"https://journals.aps.org/pra/abstract/10.1103/PhysRevA.105.042210"}],"doi":"10.1103/physreva.105.042210","citation":{"apa":"Held, P., Engelkemeier, M., De, S., Barkhofen, S., Sperling, J., &#38; Silberhorn, C.

Such structures can be fabricated through epitaxial lift-off using selective etching of Al-containing layers and subsequent transfer to glass substrates. Herein, the selective etching of (111)B-oriented AlxGa1−xAs sacrificial layers (10–50 nm thick) with different aluminum concentrations (x = 0.5–1.0) in 10\\% hydrofluoric acid is investigated and compared with standard (100)-oriented structures. The thinner the sacrificial layer and the lower the aluminum content, the lower the lateral etch rate. For both orientations, the lateral etch rates are in the same order of magnitude, but some quantitative differences exist. Furthermore, the epitaxial lift-off, the transfer, and the nanopatterning of thin (111)B-oriented GaAs membranes are demonstrated. Atomic force microscopy and high-resolution X-ray diffraction measurements reveal the high structural quality of the transferred GaAs-(111) films."}]},{"intvolume":"       557","publication_status":"published","date_updated":"2022-01-06T06:54:41Z","publication_identifier":{"issn":["0022-0248"]},"author":[{"full_name":"Albert, M.","last_name":"Albert","first_name":"M."},{"first_name":"C.","last_name":"Golla","full_name":"Golla, C."},{"id":"20798","full_name":"Meier, Cedrik","first_name":"Cedrik","orcid":"https://orcid.org/0000-0002-3787-3572","last_name":"Meier"}],"status":"public","title":"Optical in-situ temperature management for high-quality ZnO molecular beam epitaxy","year":"2021","volume":557,"user_id":"20798","doi":"10.1016/j.jcrysgro.2020.126009","_id":"20900","language":[{"iso":"eng"}],"article_number":"126009","project":[{"name":"TRR 142","_id":"53"},{"_id":"55","name":"TRR 142 - Project Area B"},{"_id":"66","name":"TRR 142 - Subproject B1"}],"citation":{"mla":"Albert, M., et al. “Optical In-Situ Temperature Management for High-Quality ZnO Molecular Beam Epitaxy.” <i>Journal of Crystal Growth</i>, vol. 557, 126009, 2021, doi:<a href=\"https://doi.org/10.1016/j.jcrysgro.2020.126009\">10.1016/j.jcrysgro.2020.126009</a>.","bibtex":"@article{Albert_Golla_Meier_2021, title={Optical in-situ temperature management for high-quality ZnO molecular beam epitaxy}, volume={557}, DOI={<a href=\"https://doi.org/10.1016/j.jcrysgro.2020.126009\">10.1016/j.jcrysgro.2020.126009</a>}, number={126009}, journal={Journal of Crystal Growth}, author={Albert, M. and Golla, C. and Meier, Cedrik}, year={2021} }","ama":"Albert M, Golla C, Meier C.

Owing to huge band offsets, the structures offer resonant transitions in the telecom window around 1.55 µm. These heterostructures are functionalized with an array of plasmonic antennas featuring cross-polarized resonances at these near-infrared wavelengths and their second harmonic. This kind of nonlinear metasurface allows for substantial second-harmonic generation at normal incidence which is completely absent for an antenna array without the multi-quantum well structure underneath. While the second harmonic is originally radiated only into the plane of the quantum wells, a proper geometrical arrangement of the plasmonic elements permits the redirection of the second-harmonic light to free-space radiation, which is emitted perpendicular to the surface."}],"publication":"Optical Materials Express","issue":"7","department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"429"}],"type":"journal_article","date_created":"2021-06-16T05:52:21Z","status":"public","volume":11,"user_id":"30525","_id":"22450","publisher":"OSA","project":[{"name":"TRR 142","_id":"53"},{"_id":"54","name":"TRR 142 - Project Area A"},{"name":"TRR 142 - Subproject A8","_id":"65"}],"quality_controlled":"1","citation":{"ama":"Mundry J, Spreyer F, Jmerik V, Ivanov S, Zentgraf T, Betz M.
