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."}],"publication":"Journal of luminescence","status":"public","_id":"43334","publication_status":"published","doi":"10.1016/S0022-2313(99)00065-4","date_created":"2023-04-02T20:22:36Z","main_file_link":[{"url":"https://www.sciencedirect.com/science/article/abs/pii/S0022231399000654"}],"user_id":"49063","author":[{"orcid":"0000-0001-8864-2072","last_name":"Meier","full_name":"Meier, Torsten","first_name":"Torsten","id":"344"},{"full_name":"Koch, S.W.","last_name":"Koch","first_name":"S.W."},{"last_name":"Sieh","full_name":"Sieh, C.","first_name":"C."},{"first_name":"F.","last_name":"Jahnke","full_name":"Jahnke, F."},{"last_name":"Knorr","full_name":"Knorr, A.","first_name":"A."},{"full_name":"Brick, P.","last_name":"Brick","first_name":"P."},{"full_name":"Hübner, M.","last_name":"Hübner","first_name":"M."},{"full_name":"Ell, C.","last_name":"Ell","first_name":"C."},{"first_name":"J.","full_name":"Prineas, J.","last_name":"Prineas"},{"first_name":"G.","last_name":"Khitrova ","full_name":"Khitrova , G."},{"first_name":"H.M.","full_name":"Gibbs, H.M.","last_name":"Gibbs"}],"year":"1999","citation":{"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} }","apa":"Meier, T., Koch, S.
