Here, we investigate spectral topology and EPs in systems with significant nonlinearity, exemplified by a nonequilibrium exciton-polariton condensate. With the possibility to control loss and gain and nonlinearity by optical means, this system allows for a comprehensive analysis of the interplay of nonlinearities (Kerr type and saturable gain) and non-Hermiticity. Not only do we find that EPs can be intentionally shifted in parameter space by the saturable gain, but we also observe intriguing rotations and intersections of Riemann surfaces and find nonlinearity-enhanced sensing capabilities. With this, our results illustrate the potential of tailoring spectral topology and related phenomena in non-Hermitian systems by nonlinearity.</jats:p>\r\n          <jats:sec>\r\n            <jats:title/>\r\n            <jats:supplementary-material>\r\n              <jats:permissions>\r\n                <jats:copyright-statement>Published by the American Physical Society</jats:copyright-statement>\r\n                <jats:copyright-year>2024</jats:copyright-year>\r\n              </jats:permissions>\r\n            </jats:supplementary-material>\r\n          </jats:sec>","lang":"eng"}],"_id":"61257","publisher":"American Physical Society (APS)","volume":6,"user_id":"16199","status":"public","citation":{"ama":"Wingenbach J, Schumacher S, Ma X.

Especially for 2D materials, the atomic electric fields influence the optoelectronic properties. In this study, the atomic‐scale electric field and charge density distribution of WSe<jats:sub>2</jats:sub> bi‐ and trilayers are revealed using an emerging microscopy technique, differential phase contrast (DPC) imaging in scanning transmission electron microscopy (STEM). For pristine material, a higher positive charge density located at the selenium atomic columns compared to the tungsten atomic columns is obtained and tentatively explained by a coherent scattering effect. Furthermore, the change in the electric field distribution induced by a missing selenium atomic column is investigated. A characteristic electric field distribution in the vicinity of the defect with locally reduced magnitudes compared to the pristine lattice is observed. This effect is accompanied by a considerable inward relaxation of the surrounding lattice, which according to first principles DFT calculation is fully compatible with a missing column of Se atoms. This shows that DPC imaging, as an electric field sensitive technique, provides additional and remarkable information to the otherwise only structural analysis obtained with conventional STEM imaging.</jats:p>"}],"date_created":"2024-06-24T09:46:25Z","department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"790"},{"_id":"642"},{"_id":"286"},{"_id":"429"},{"_id":"230"},{"_id":"27"},{"_id":"35"},{"_id":"169"}],"type":"journal_article"},{"doi":"10.1088/1742-6596/2701/1/012094","language":[{"iso":"eng"}],"article_number":"012094","intvolume":"      2701","date_updated":"2025-12-05T13:36:01Z","publication_status":"published","publication_identifier":{"issn":["1742-6588","1742-6596"]},"author":[{"first_name":"Katharina","last_name":"Franzke","full_name":"Franzke, Katharina"},{"id":"468","full_name":"Schmidt, Wolf Gero","orcid":"0000-0002-2717-5076","first_name":"Wolf Gero","last_name":"Schmidt"},{"first_name":"Uwe","last_name":"Gerstmann","orcid":"0000-0002-4476-223X","full_name":"Gerstmann, Uwe","id":"171"}],"year":"2024","title":"Relativistic calculation of the orbital hyperfine splitting in complex microscopic structures","department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"790"},{"_id":"230"},{"_id":"429"},{"_id":"27"},{"_id":"35"}],"type":"journal_article","date_created":"2024-06-24T06:26:02Z","abstract":[{"lang":"eng","text":"<jats:title>Abstract</jats:title>\r\n               <jats:p>Theoretical spectroscopy based on double perturbation theory is typically challenged by systems with large orbital hyperfine splitting.

The underlying scheme is based on the manipulation of ground state coherences through precise optical driving. One important finding is that the most easily accessible quality metrics, the achievable rotation fidelities, fall short in assessing the actual quantum correlations of the emitted photons in the face of losses. To address this, we explicitly calculate stabilizer generator expectation values as a superior gauge for the quantum properties of the generated many-photon state. With widespread applicability in other emitter and excitation–emission schemes also, our work lays the conceptual foundations for an in-depth practical analysis of time-bin entanglement based on full numerical simulations with predictive capabilities for realistic systems and setups, including losses and imperfections.

While various methods have been proposed and explored, they all have specific advantages and disadvantages. This study investigates the dynamics of the recent swing‐up scheme as an excitation method for a two‐level system and its performance in single‐photon generation. By applying two far red‐detuned laser pulses, the two‐level system can be prepared in the excited state with near‐unity fidelity. The successful operation and coherent character of this technique are demonstrated using a semiconductor quantum dot (QD). Moreover, the multi‐dimensional parameter space of the two laser pulses is explored to analyze its impact on excitation fidelity. Finally, the performance of the scheme as an excitation method for generating high‐quality single photons is analyzed. The swing‐up scheme itself proves effective, exhibiting nearly perfect single‐photon purity, while the observed indistinguishability in the studied sample is limited by the influence of the inevitable high excitation powers on the semiconductor environment of the quantum dot.</jats:p>","lang":"eng"}],"issue":"4","publication":"Advanced Quantum Technologies","doi":"10.1002/qute.202300359","article_number":"2300359","language":[{"iso":"eng"}],"date_updated":"2025-12-11T13:00:06Z","publication_status":"published","intvolume":"         7","title":"Coherent Swing‐Up Excitation for Semiconductor Quantum Dots","year":"2024","publication_identifier":{"issn":["2511-9044","2511-9044"]},"author":[{"first_name":"Katarina","last_name":"Boos","full_name":"Boos, Katarina"},{"full_name":"Sbresny, Friedrich","last_name":"Sbresny","first_name":"Friedrich"},{"last_name":"Kim","first_name":"Sang Kyu","full_name":"Kim, Sang Kyu"},{"full_name":"Kremser, Malte","first_name":"Malte","last_name":"Kremser"},{"full_name":"Riedl, Hubert","last_name":"Riedl","first_name":"Hubert"},{"last_name":"Bopp","first_name":"Frederik W.","full_name":"Bopp, Frederik W."},{"first_name":"William","last_name":"Rauhaus","full_name":"Rauhaus, William"},{"last_name":"Scaparra","first_name":"Bianca","full_name":"Scaparra, Bianca"},{"last_name":"Jöns","first_name":"Klaus","full_name":"Jöns, Klaus","id":"85353"},{"last_name":"Finley","first_name":"Jonathan J.","full_name":"Finley, Jonathan J."},{"full_name":"Müller, Kai","first_name":"Kai","last_name":"Müller"},{"first_name":"Lukas","last_name":"Hanschke","full_name":"Hanschke, Lukas"}]},{"date_updated":"2025-12-11T12:54:41Z","author":[{"first_name":"L.","last_name":"Hanschke","full_name":"Hanschke, L."},{"full_name":"Bracht, T.

Semiconductor quantum dots (QDs) are attractive candidates that emit high-quality quantum states of light on demand, however at a rate limited by their spontaneous radiative lifetime. In this study, we utilize the Purcell effect to demonstrate up to a 38-fold enhancement in the emission rate of InAs QDs by coupling them to metal-clad GaAs nanopillars. These cavities, featuring a sub-wavelength mode volume of 4.5x10-4 (λ/n)3 and low quality factor of 62, enable Purcell-enhanced single-photon emission across a large bandwidth of 15 nm. The broadband nature of the cavity eliminates the need for implementing tuning mechanisms typically required to achieve QD-cavity resonance, thus relaxing fabrication constraints. Ultimately, this QD-cavity architecture represents a significant stride towards developing solid-state quantum emitters generating near-ideal single-photon states at GHz-level repetition rates."}],"citation":{"short":"K.

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.</jats:p>","lang":"eng"}],"date_created":"2024-06-24T06:15:00Z","department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"288"},{"_id":"230"},{"_id":"429"}],"type":"journal_article","status":"public","_id":"54852","publisher":"MDPI AG","volume":13,"user_id":"16199","citation":{"mla":"Neufeld, Sergej, et al. “Vibrational Properties of the Potassium Titanyl Phosphate Crystal Family.” <i>Crystals</i>, vol. 13, no. 10, 1423, MDPI AG, 2023, doi:<a href=\"https://doi.org/10.3390/cryst13101423\">10.3390/cryst13101423</a>.","ama":"Neufeld S, Gerstmann U, Padberg L, et al.

According to our calculations, RTP:F is expected to retain the so-called KTiOPO4 (KTP)-type structure, with lattice parameters of 13.236 Å, 6.616 Å, and 10.945 Å. Due to the doping with F, the crystal features eight extra electrons per unit cell, whereby each of these electrons is trapped by one of the surrounding Ti atoms in the cell. Notably, the ground state of the system corresponds to a ferromagnetic spin configuration (i.e., S=4). The deintercalation of Rb leads to the oxidation of the Ti atoms in the cell (i.e., from Ti3+ to Ti4+) and to reduced magnetic moments.
