By the Stark effect, a time-dependent electric signal is converted into a time-dependent shift of the transition energy. This shift is measured accurately by resonant ps laser spectroscopy with photocurrent detection. In our experiments, we sample the laser synchronous output pulse of an ultrafast CMOS circuit with high resolution. With our quantum dot sensor device, we were able to sample transients below 20 ps with a voltage resolution in the mV-range.","lang":"eng"}],"language":[{"iso":"eng"}],"keyword":["tet_topic_qd"],"ddc":["530"],"has_accepted_license":"1","publication_identifier":{"issn":["0003-6951","1077-3118"]},"publication_status":"published","page":"181109","intvolume":"       119","citation":{"ieee":"A.

However, the underlying collision dynamics behind solid HHG is still intensively debated and no direct mapping relationship between the collision dynamics with band structure has been built. Here, we show that the electron and its associated hole can be elastically scattered by neighboring atoms when their wavelength approaches the atomic size. We reveal that the elastic scattering of electron/hole from neighboring atoms can dramatically influence the electron recombination with its left-behind hole, which turns out to be the fundamental reason for the anisotropic interband HHG observed recently in bulk crystals. Our findings link the electron/hole backward scattering with Van Hove singularities and forward scattering with critical lines in the band structure and thus build a clear mapping between the band structure and the harmonic spectrum. Our work provides a unifying picture for several seemingly unrelated experimental observations and theoretical predictions, including the anisotropic harmonic emission in MgO, the atomic-like recollision mechanism of solid HHG, and the delocalization of HHG in ZnO. This strongly improved understanding will pave the way for controlling the solid-state HHG and visualizing the structure-dependent electron dynamics in solids.</jats:p>","lang":"eng"}],"volume":2021,"author":[{"full_name":"Zuo, Ruixin","last_name":"Zuo","first_name":"Ruixin"},{"first_name":"Alexander","last_name":"Trautmann","full_name":"Trautmann, Alexander","id":"38163"},{"first_name":"Guifang","full_name":"Wang, Guifang","last_name":"Wang"},{"first_name":"Wolf-Rüdiger","last_name":"Hannes","full_name":"Hannes, Wolf-Rüdiger"},{"first_name":"Shidong","full_name":"Yang, Shidong","last_name":"Yang"},{"first_name":"Xiaohong","last_name":"Song","full_name":"Song, Xiaohong"},{"first_name":"Torsten","last_name":"Meier","orcid":"0000-0001-8864-2072","id":"344","full_name":"Meier, Torsten"},{"first_name":"Marcelo","last_name":"Ciappina","full_name":"Ciappina, Marcelo"},{"first_name":"Huynh Thanh","last_name":"Duc","full_name":"Duc, Huynh Thanh"},{"first_name":"Weifeng","last_name":"Yang","full_name":"Yang, Weifeng"}],"date_created":"2023-01-18T11:25:42Z","publisher":"American Association for the Advancement of Science (AAAS)","date_updated":"2023-04-21T11:11:08Z","doi":"10.34133/2021/9861923","title":"Neighboring Atom Collisions in Solid-State High Harmonic Generation","publication_identifier":{"issn":["2765-8791"]},"publication_status":"published","intvolume":"      2021","citation":{"ieee":"R.

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":"Crystals","title":"Electron polarons in lithium niobate: Charge localization, lattice deformation, and optical response","date_created":"2021-05-03T09:36:13Z","publisher":"MDPI","year":"2021","quality_controlled":"1","file_date_updated":"2021-05-13T16:51:41Z","funded_apc":"1","article_type":"original","isi":"1","user_id":"171","department":[{"_id":"296"},{"_id":"230"},{"_id":"429"},{"_id":"295"},{"_id":"15"},{"_id":"170"},{"_id":"35"},{"_id":"790"}],"project":[{"_id":"53","name":"TRR 142"},{"name":"TRR 142 - Project Area B","_id":"55"},{"name":"TRR 142 - Subproject B4","_id":"69"},{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"_id":"21946","status":"public","type":"journal_article","doi":"10.3390/cryst11050542","author":[{"first_name":"Falko","orcid":"0000-0002-5071-5528","last_name":"Schmidt","id":"35251","full_name":"Schmidt, Falko"},{"full_name":"Kozub, Agnieszka L.","id":"77566","last_name":"Kozub","orcid":"https://orcid.org/0000-0001-6584-0201","first_name":"Agnieszka L."},{"id":"171","full_name":"Gerstmann, Uwe","last_name":"Gerstmann","orcid":"0000-0002-4476-223X","first_name":"Uwe"},{"full_name":"Schmidt, Wolf Gero","id":"468","orcid":"0000-0002-2717-5076","last_name":"Schmidt","first_name":"Wolf Gero"},{"first_name":"Arno","orcid":"0000-0002-4855-071X","last_name":"Schindlmayr","id":"458","full_name":"Schindlmayr, Arno"}],"volume":11,"date_updated":"2023-04-21T11:20:15Z","oa":"1","citation":{"ama":"Schmidt F, Kozub AL, Gerstmann U, Schmidt WG, Schindlmayr A.

Therefore, this effect is usually undesirable and must be compensated for. However, high gain may be used to overcome the destructive role of anisotropy in order to generate bright two-mode correlated twin-beams. In this work, we provide a rigorous theoretical description of the spatial properties of bright squeezed light in the presence of strong anisotropy. We investigate a single crystal and a system of two crystals with an air gap (corresponding to a nonlinear SU(1,1) interferometer) and demonstrate the generation of bright correlated twin-beams in such configurations at high gain due to anisotropy. We explore the mode structure of the generated light and show how anisotropy, together with crystal spacing, can be used for radiation shaping.</jats:p>","lang":"eng"}],"status":"public","publication":"Optics Express","type":"journal_article","title":"Bright correlated twin-beam generation and radiation shaping in high-gain parametric down-conversion with anisotropy","doi":"10.1364/oe.424977","date_updated":"2023-04-20T14:58:35Z","publisher":"Optica Publishing Group","volume":29,"author":[{"first_name":"M.","last_name":"Riabinin","full_name":"Riabinin, M."},{"first_name":"Polina","id":"60286","full_name":"Sharapova, Polina","last_name":"Sharapova"},{"id":"344","full_name":"Meier, Torsten","last_name":"Meier","orcid":"0000-0001-8864-2072","first_name":"Torsten"}],"date_created":"2023-01-18T11:31:53Z","year":"2021","intvolume":"        29","page":"21876-21890","citation":{"chicago":"Riabinin, M., Polina Sharapova, and Torsten Meier. “Bright Correlated Twin-Beam Generation and Radiation Shaping in High-Gain Parametric down-Conversion with Anisotropy.” <i>Optics Express</i> 29, no. 14 (2021): 21876–90. <a href=\"https://doi.org/10.1364/oe.424977\">https://doi.org/10.1364/oe.424977</a>.","ieee":"M.

Defect trapped polarons and bipolarons are found to strongly enhance the nonlinear susceptibility of the material, in particular if localized at NbV–VLi defect pairs. This is essentially a consequence of the polaronic excitation resulting in relaxation-induced gap states. The occupation of these levels leads to strongly enhanced χ(2) coefficients and allows for the spatial and transient modification of the second-harmonic generation of macroscopic samples.","lang":"eng"}],"date_created":"2021-08-16T19:09:46Z","publisher":"American Physical Society","title":"Polaronic enhancement of second-harmonic generation in lithium niobate","quality_controlled":"1","year":"2021","user_id":"171","department":[{"_id":"296"},{"_id":"230"},{"_id":"429"},{"_id":"295"},{"_id":"15"},{"_id":"170"},{"_id":"790"}],"project":[{"name":"TRR 142","_id":"53"},{"_id":"55","name":"TRR 142 - Project Area B"},{"_id":"69","name":"TRR 142 - Subproject B4"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"_id":"23418","file_date_updated":"2021-11-18T20:49:19Z","isi":"1","article_type":"original","type":"journal_article","status":"public","author":[{"first_name":"Agnieszka L.","orcid":"https://orcid.org/0000-0001-6584-0201","last_name":"Kozub","full_name":"Kozub, Agnieszka L.","id":"77566"},{"orcid":"0000-0002-4855-071X","last_name":"Schindlmayr","full_name":"Schindlmayr, Arno","id":"458","first_name":"Arno"},{"first_name":"Uwe","id":"171","full_name":"Gerstmann, Uwe","last_name":"Gerstmann","orcid":"0000-0002-4476-223X"},{"orcid":"0000-0002-2717-5076","last_name":"Schmidt","full_name":"Schmidt, Wolf Gero","id":"468","first_name":"Wolf Gero"}],"volume":104,"oa":"1","date_updated":"2023-04-21T11:15:30Z","doi":"10.1103/PhysRevB.104.174110","publication_status":"published","publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"has_accepted_license":"1","citation":{"ama":"Kozub AL, Schindlmayr A, Gerstmann U, Schmidt WG.
