The 266 nm (4.66 eV) pump pulses induce a large electron–hole pair concentration up to 4×1020cm−3, which shift the transition energy between conduction and valence bands due to many-body effects up to ≈500 meV. Here, the absorption onset increases due to band filling while the bandgap renormalization at the same time decreases the bandgap. Additionally, the absorption of the pump-beam creates a free-carrier profile within the 605 nm zb-GaN layer with high free-carrier concentrations at the surface, and low concentrations at the interface to the substrate. This leads to varying optical properties from the sample surface (high transition energy) to substrate (low transition energy), which are taken into account by grading analysis for an accurate description of the experimental data. For this, a model describing the time- and position-dependent free-carrier concentration is formulated by considering the relaxation, recombination, and diffusion of those carriers. We provide a quantitative analysis of optical experimental data (ellipsometric angles Ψ and Δ) as well as a plot for the time-dependent change of the imaginary part of the dielectric function."}],"publication":"Journal of Applied Physics","issue":"7","department":[{"_id":"15"},{"_id":"230"}],"type":"journal_article","keyword":["General Physics and Astronomy"],"date_created":"2023-08-18T08:17:41Z","status":"public","volume":134,"user_id":"14931","_id":"46573","publisher":"AIP Publishing","citation":{"ama":"Baron E, Goldhahn R, Espinoza S, et al.

Our in-depth theoretical study combines (i) the optimization of realistic photonic structures solving Maxwell's equations from which model parameters are extracted as input for (ii) microscopic simulations of quantum-dot cavity excitation dynamics with full access to photon properties. We report non-trivial dependencies on system parameters and use the predictive power of our combined theoretical approach to determine the optimal range of Purcell enhancement that maximizes indistinguishability and entanglement to near unity values in the telecom C-band at $1550\\,\\mathrm{nm}$."}],"related_material":{"record":[{"id":"48599","relation":"later_version","status":"public"}]}},{"date_created":"2024-02-27T13:57:01Z","department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"}],"keyword":["General Physics and Astronomy"],"type":"journal_article","publication":"Physical Review Research","issue":"4","language":[{"iso":"eng"}],"article_number":"043152","doi":"10.1103/physrevresearch.5.043152","author":[{"full_name":"Ali, Usman","first_name":"Usman","last_name":"Ali"},{"full_name":"Holthaus, Martin","first_name":"Martin","last_name":"Holthaus"},{"id":"344","first_name":"Torsten","last_name":"Meier","orcid":"0000-0001-8864-2072","full_name":"Meier, Torsten"}],"publication_identifier":{"issn":["2643-1564"]},"title":"Chirped Bloch-harmonic oscillations in a parametrically forced optical lattice","year":"2023","intvolume":" 5","date_updated":"2024-02-28T12:53:40Z","publication_status":"published","citation":{"ama":"Ali U, Holthaus M, Meier T.

The underlying mechanism is attributed to the modified rotation of the effective principal axis of a dense meta-atom array, where the strong coupling among the units gives rise to a generalized linear geometric phase modulation of the pump light. Therefore, nonlinear geometric phases carried by third-harmonic emissions are the natural result of the wave-mixing process among the modes excited at the fundamental frequency.

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.","lang":"eng"}],"publication":"Crystals","issue":"10","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"288"},{"_id":"230"},{"_id":"429"}],"date_created":"2024-06-24T06:15:00Z","date_updated":"2024-06-24T06:30:23Z","publication_status":"published","intvolume":" 13","year":"2023","title":"Vibrational Properties of the Potassium Titanyl Phosphate Crystal Family","author":[{"full_name":"Neufeld, Sergej","last_name":"Neufeld","first_name":"Sergej"},{"full_name":"Gerstmann, Uwe","orcid":"0000-0002-4476-223X","last_name":"Gerstmann","first_name":"Uwe","id":"171"},{"id":"40300","full_name":"Padberg, Laura","last_name":"Padberg","first_name":"Laura"},{"full_name":"Eigner, Christof","last_name":"Eigner","first_name":"Christof","orcid":"https://orcid.org/0000-0002-5693-3083","id":"13244"},{"id":"53","full_name":"Berth, Gerhard","last_name":"Berth","first_name":"Gerhard"},{"id":"26263","full_name":"Silberhorn, Christine","last_name":"Silberhorn","first_name":"Christine"},{"full_name":"Eng, Lukas M.","first_name":"Lukas M.","last_name":"Eng"},{"full_name":"Schmidt, Wolf Gero","last_name":"Schmidt","orcid":"0000-0002-2717-5076","first_name":"Wolf Gero","id":"468"},{"orcid":"0000-0003-4682-4577","last_name":"Rüsing","first_name":"Michael","full_name":"Rüsing, Michael","id":"22501"}],"publication_identifier":{"issn":["2073-4352"]},"doi":"10.3390/cryst13101423","article_number":"1423","language":[{"iso":"eng"}],"project":[{"_id":"53","grant_number":"231447078","name":"TRR 142: TRR 142 - Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"}],"citation":{"ieee":"S.

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. The material promises interesting electrochemical properties for the cathode: rather high average voltages above 2.8 V and modest volume shrinkages below 13% even in the fully deintercalated case are predicted.","lang":"eng"}],"publication":"Crystals","issue":"1","doi":"10.3390/cryst14010005","article_number":"5","language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2024-06-24T06:30:13Z","intvolume":" 14","title":"Structural and Electrochemical Properties of F-Doped RbTiOPO4 (RTP:F) Predicted from First Principles","year":"2023","publication_identifier":{"issn":["2073-4352"]},"author":[{"id":"58349","orcid":"0000-0002-2134-3075","first_name":"Adriana","last_name":"Bocchini","full_name":"Bocchini, Adriana"},{"full_name":"Xie, Yingjie","first_name":"Yingjie","last_name":"Xie"},{"id":"468","full_name":"Schmidt, Wolf Gero","first_name":"Wolf Gero","orcid":"0000-0002-2717-5076","last_name":"Schmidt"},{"id":"171","full_name":"Gerstmann, Uwe","orcid":"0000-0002-4476-223X","first_name":"Uwe","last_name":"Gerstmann"}]},{"doi":"10.1063/5.0170099","language":[{"iso":"eng"}],"intvolume":" 134","publication_status":"published","date_updated":"2024-06-24T06:30:19Z","publication_identifier":{"issn":["0021-8979","1089-7550"]},"author":[{"first_name":"F.

We observed that the four inequivalent NV configurations (hk, kh, hh, and kk) exhibit different electron–nuclear interaction parameters, suggesting that each NV center may act as a separate optically addressable qubit. Finally, we rationalized the observed differences in terms of distinctions in the local atomic structures of the NV configurations. Thus, our results provide the basic knowledge for an extension of quantum protocols involving the 14N nuclear spin."}],"issue":"12","publication":"Journal of Applied Physics","volume":134,"user_id":"16199","_id":"54853","publisher":"AIP Publishing","status":"public","project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"citation":{"mla":"Murzakhanov, F.
