The array was fabricated by electron beam lithography and several steps of reactive ion etching (RIE) with the help of a hard mask and an undercut of the active layer. The r/a- ratio of 0.35 was deter- mined by numerical simulations to obtain a preferably wide photonic band gap. Micro-photoluminescence (μ-PL) measurements of the photonic crystals, in particular of a H1 and a L3 cavity, and the emission of the QD ensemble were performed to characterize the samples. The PhCs show high quality factors of 4400 for the H1 cavity and about 5000/3000 for two different modes of the L3 cavity, respectively. The energy of the fundamental modes is in good agreement to the numerical simulations.

The HRXRD analysis reveals a reduction of the full-width at half-maximum (FWHM) of omega scans for growing layer thicknesses, which is caused by a partial compensation of defects. The Raman characterization confirms well-formed c-GaN layers. A more detailed examination of the longitudinal optical mode hints at a correlation of the FWHM of the Raman mode with the dislocation density, which shows the possibility to determine dislocation densities by Ramanspectroscopy on a micrometer scale, which is not possible by HRXRD.

The opal films are deposited via sedimentation facilitated by ultrasonication, and then impregnated by indium nitrate solution, which is thermally converted to In2O3 after drying. The quality of the resulting inverse opal film depends on many parameters; in this study the water content of the indium nitrate/PMMA composite after drying is investigated. Comparison of the reflectance spectra recorded by vis-spectroscopy with simulated data shows a good agreement between the peak position and calculated stop band positions for the inverse opals.

The system can be implemented in binary Bose-Einstein condensates, demonstrating the potential of the atomic condensates to emulate various complex modes predicted by classical field theories. First, the GA very accurately predicts a broadly degenerate set of the system's ground states in the p-wave manifold, in the form of complexes built of a dipole coaxial with another dipole or vortex, as well as complexes built of mutually orthogonal dipoles. Next, pairs of noncoaxial vortices and/or dipoles, including pairs of mutually perpendicular vortices, develop remarkably stable dynamical regimes, which feature periodic exchange of the angular momentum and periodic switching between dipoles and vortices. For a moderately strong nonlinearity, simulations of the coupled-field equations agree very well with results produced by the GA, demonstrating that the dynamics is accurately spanned by the set of six modes limited to l=1.","lang":"eng"}],"issue":"1","publication":"Physical Review E","department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"}],"type":"journal_article","date_created":"2019-10-18T08:29:20Z","status":"public","volume":94,"user_id":"49063","funded_apc":"1","_id":"13915","citation":{"ieee":"R.

This approach provides a transparent description of the interband, intersubband, and intraband excitations, fully includes all resonant as well as off-resonant excitations, and treats the light-matter interaction nonperturbatively. For linearly polarized excitations, the photocurrents contain contributions from shift and rectification currents. We numerically compute and analyze these currents generated by excitation with femtosecond laser pulses for [110]- and [111]-oriented GaAs quantum wells. It is shown that the often employed perturbative \r\nχ(2) approach breaks down for peak fields larger than about 10 kV/cm, and that nonperturbative effects lead to a reduction of the peak values of the shift and rectification currents and to temporal oscillations that originate from Rabi flopping. In particular, we find a complex oscillatory photon energy dependence of the magnitudes of the shift and rectification currents. Our simulations demonstrate that this dependence is the result of mixing between the heavy- and light-hole valence bands. This is a surprising finding since the band mixing has an even larger influence on the strength of the photocurrents than the absorption coefficient. For [110]-oriented GaAs quantum wells, the calculated photon energy dependence is compared to experimental results, and good agreement is obtained. This validates our theoretical approach."}],"issue":"8","publication":"Physical Review B","doi":"10.1103/physrevb.94.085305","article_number":"085305","language":[{"iso":"eng"}],"date_updated":"2023-04-16T21:18:16Z","publication_status":"published","intvolume":" 94","year":"2016","title":"Ultrafast shift and rectification photocurrents in GaAs quantum wells: Excitation intensity dependence and the importance of band mixing","author":[{"full_name":"Duc, Huynh Thanh","first_name":"Huynh Thanh","last_name":"Duc"},{"full_name":"Podzimski, Reinold","last_name":"Podzimski","first_name":"Reinold"},{"last_name":"Priyadarshi","first_name":"Shekhar","full_name":"Priyadarshi, Shekhar"},{"full_name":"Bieler, Mark","first_name":"Mark","last_name":"Bieler"},{"full_name":"Meier, Torsten","orcid":"0000-0001-8864-2072","last_name":"Meier","first_name":"Torsten","id":"344"}],"publication_identifier":{"issn":["2469-9950","2469-9969"]},"project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"citation":{"short":"H.T.

Localized nonlinear modes have been the focus of intense research in areas such as fluid and gas dynamics, photonics, atomic and solid state physics etc. Due to the richness of the behavior of nonlinear systems and due to the severe numerical demands of accurate three-dimensional (3D) numerical simulations presently only little knowledge is available on the dynamics of complex nonlinear modes in 3D. Here, we investigate the dynamics of 3D non-coaxial matter wave vortices that are trapped in a parabolic potential and interact via a repulsive nonlinearity. Our numerical simulations demonstrate the existence of an unexpected and fascinating nonlinear regime that starts immediately when the nonlinearity is switched-on and is characterized by a smooth dynamics representing torque-free precession with nutations. The reported motion is proven to be robust regarding various effects such as the number of particles, dissipation and trap deformations and thus should be observable in suitably designed experiments. Since our theoretical approach, i.e., coupled nonlinear Schrödinger equations, is quite generic, we expect that the obtained novel dynamical behavior should also exist in other nonlinear systems.","lang":"eng"}],"date_created":"2019-10-18T08:30:23Z","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"}],"year":"2016","title":"Precession and nutation dynamics of nonlinearly coupled non-coaxial three-dimensional matter wave vortices","author":[{"full_name":"Driben, R.","first_name":"R.","last_name":"Driben"},{"last_name":"Konotop","first_name":"V.

Self-energy calculations in the GW approximation show that the inclusion of self-consistency in the Green function G and the screened Coulomb potential W opens the band gap far stronger than found in previous G0W0 calculations but slightly overestimates its actual value due to the neglect of excitonic effects in W. A realistic frozen-lattice band gap of about 5.9 eV is obtained by combining hybrid density functional theory with the QSGW0 scheme. The renormalization of the band gap due to electron-phonon coupling, derived here using molecular dynamics as well as density functional perturbation theory, reduces this value by about 0.5 eV at room temperature. Spin-orbit coupling does not noticeably modify the fundamental gap but gives rise to a Rashba-like spin texture in the conduction band.","lang":"eng"}],"file":[{"content_type":"application/pdf","file_id":"18469","title":"LiNbO3 electronic structure: Many-body interactions, spin-orbit coupling, and thermal effects","file_size":1314637,"access_level":"open_access","file_name":"PhysRevB.93.075205.pdf","date_updated":"2020-08-30T14:39:23Z","relation":"main_file","date_created":"2020-08-27T20:36:43Z","description":"© 2016 American Physical Society","creator":"schindlm"}],"date_created":"2019-05-29T07:50:59Z","type":"journal_article","department":[{"_id":"295"},{"_id":"296"},{"_id":"230"},{"_id":"429"},{"_id":"790"},{"_id":"15"},{"_id":"35"},{"_id":"27"}],"year":"2016","title":"LiNbO3 electronic structure: Many-body interactions, spin-orbit coupling, and thermal effects","publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"author":[{"full_name":"Riefer, Arthur","first_name":"Arthur","last_name":"Riefer"},{"first_name":"Michael","last_name":"Friedrich","full_name":"Friedrich, Michael"},{"full_name":"Sanna, Simone","first_name":"Simone","last_name":"Sanna"},{"id":"171","last_name":"Gerstmann","orcid":"0000-0002-4476-223X","first_name":"Uwe","full_name":"Gerstmann, Uwe"},{"id":"458","full_name":"Schindlmayr, Arno","orcid":"0000-0002-4855-071X","first_name":"Arno","last_name":"Schindlmayr"},{"id":"468","full_name":"Schmidt, Wolf Gero","orcid":"0000-0002-2717-5076","first_name":"Wolf Gero","last_name":"Schmidt"}],"publication_status":"published","date_updated":"2025-12-05T09:59:57Z","article_type":"original","intvolume":" 93","article_number":"075205","language":[{"iso":"eng"}],"doi":"10.1103/PhysRevB.93.075205","file_date_updated":"2020-08-30T14:39:23Z","isi":"1","citation":{"chicago":"Riefer, Arthur, Michael Friedrich, Simone Sanna, Uwe Gerstmann, Arno Schindlmayr, and Wolf Gero Schmidt. “LiNbO3 Electronic Structure: Many-Body Interactions, Spin-Orbit Coupling, and Thermal Effects.” Physical Review B 93, no. 7 (2016). https://doi.org/10.1103/PhysRevB.93.075205.","short":"A.

The longitudinal optical phonon modes are theoretically derived and compared with available experimental data. Our results confirm the recent phonon assignment proposed by Margueron et al. [J. Appl. Phys. 111, 104105 (2012)] on the basis of spectroscopical studies. A comparison with the phonon band structure of the related material LiNbO3 shows minor differences that can be traced to the atomic‐mass difference between Ta and Nb. The presence of phonons with imaginary frequencies for the paraelectric phase suggests that it does not correspond to a minimum energy structure, and is compatible with an order‐disorder type phase transition."}],"publication":"Physica Status Solidi B","issue":"4"}]
