[{"abstract":[{"text":"A microscopic theory is applied to discuss coherent excitation effects in semiconductors. The theory is evaluated to analyze ultrafast absorption changes around the exciton resonance in semiconductor quantum-well structures where the relative strength of the different many-body contributions can be manipulated by proper selection of pump and probe polarizations. For two-band systems and oppositely circular polarization it is shown that Coulombic correlation dynamics dominates the optical response. As a consequence, the optical Stark effect in this configuration corresponds to a red shift of the exciton resonance in striking contrast to the usual atomic-like blue shift. The predictions are confirmed by experiments using high-quality InGaAs quantum-well systems.","lang":"eng"}],"status":"public","type":"journal_article","publication":"Journal of luminescence","language":[{"iso":"eng"}],"extern":"1","_id":"43334","user_id":"49063","department":[{"_id":"293"}],"year":"1999","citation":{"mla":"Meier, Torsten, et al. “Theory of Coherent Effects in Semiconductors.” <i>Journal of Luminescence</i>, vol. 83/84, Journal of luminescence, 1999, pp. 1–6, doi:<a href=\"https://doi.org/10.1016/S0022-2313(99)00065-4\">10.1016/S0022-2313(99)00065-4</a>.","bibtex":"@article{Meier_Koch_Sieh_Jahnke_Knorr_Brick_Hübner_Ell_Prineas_Khitrova _et al._1999, title={Theory of coherent effects in semiconductors}, volume={83/84}, DOI={<a href=\"https://doi.org/10.1016/S0022-2313(99)00065-4\">10.1016/S0022-2313(99)00065-4</a>}, journal={Journal of luminescence}, publisher={Journal of luminescence}, author={Meier, Torsten and Koch, S.W. and Sieh, C. and Jahnke, F. and Knorr, A. and Brick, P. and Hübner, M. and Ell, C. and Prineas, J. and Khitrova , G. and et al.}, year={1999}, pages={1–6} }","short":"T.

Our results obtained within DFT-LDA show good qualitative agreement with recent experiments. This holds in particular for the stoichiometric trends. A strong negative anisotropy at low photon energies is linked to the formation of Ga–Ga bonds along the [110] direction. There are discrepancies, however, with respect to the line shape and the energetic positions of characteristic peaks. Substantial improvement is achieved by using a numerically efficient GW approach with approximations for local-field effects and dynamical screening. We find that the spectral features related to transitions between surface perturbed bulk wave functions are more strongly affected by self-energy corrections than anisotropies directly linked to surface electronic states. </jats:p>"}],"status":"public","publication":"Surface Review and Letters","type":"journal_article","funded_apc":"1","language":[{"iso":"eng"}],"_id":"13765","department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"35"},{"_id":"230"}],"user_id":"16199"},{"funded_apc":"1","language":[{"iso":"eng"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"35"},{"_id":"230"}],"user_id":"16199","_id":"13768","status":"public","publication":"Physical Review B","type":"journal_article","doi":"10.1103/physrevb.60.2488","title":"(2×4)GaP(001) surface: Atomic structure and optical anisotropy","volume":60,"author":[{"first_name":"A.

We aimed at a conceptually simple system: We trained two model sets on 70 hours of the Hub-4 training data, one for within-word and one for cross-word decoding. These model sets were used for both genders and all environmental conditions. In order to be able to do so, channel normalization (mean, variance normalization) and speaker normalization (vocal tract length normalization, realized by an appropriate shift of the center frequencies of the mel filter bank) have been applied, as well as adaptation techniques. MLLR-based unsupervised batch adaptation on clusters of segments was conducted both after a first within-word decoding and a cross-word decoding pass. The training strategy and the effects of the various normalization and adaptation techniques will be discussed in the paper."}],"status":"public","oa":"1","date_updated":"2022-01-06T06:51:08Z","date_created":"2019-07-12T05:28:11Z","author":[{"last_name":"Haeb-Umbach","id":"242","full_name":"Haeb-Umbach, Reinhold","first_name":"Reinhold"},{"full_name":"Aubert, Xavier L.","last_name":"Aubert","first_name":"Xavier L."},{"first_name":"Peter","full_name":"Beyerlein, Peter","last_name":"Beyerlein"},{"last_name":"Klakow","full_name":"Klakow, Dietrich","first_name":"Dietrich"},{"first_name":"Meinhard","last_name":"Ullrich","full_name":"Ullrich, Meinhard"},{"last_name":"Wendemuth","full_name":"Wendemuth, Andreas","first_name":"Andreas"},{"first_name":"Patricia","last_name":"Wilcox","full_name":"Wilcox, Patricia"}],"title":"Acoustic Modeling in the Philips Hub-4 Continuous-Speech Recognition System","main_file_link":[{"open_access":"1","url":"https://groups.uni-paderborn.de/nt/pubs/1998/Workshop_Landsdowne_1998_Haeb2_paper.pdf"}],"year":"1998","citation":{"short":"R.
