[{"language":[{"iso":"eng"}],"abstract":[{"text":"This chapter focuses on the carrier interaction effects—that is, the many-body Coulomb correlations and their influence on band-gap semiconductor optical nonlinearities. The near band-gap semiconductor response is determined by the optical interaction with the resonant or near resonant material polarization that may result in the excitation of carriers (electron–hole pairs) and/or transient coherent nonlinearities. The microscopic analysis of these effects requires the investigation of the relevant quasi-particles and their interactions. Whereas the basic occurrence of a blue shift can be motivated already based on a simple two-level model, a more detailed understanding of the optical Stark effect in semiconductors requires a microscopic modeling of the relevant bands as well as the inclusion of the many-body Coulomb interaction. Compensations among the first- and higher-order Coulomb terms at the spectral positions of the exciton are obtained in the differential absorption induced by incoherent occupations.","lang":"eng"}],"publication":"Ultrafast Physical Processes in Semiconductors","title":"Coulomb correlation signatures in the excitonic optical nonlinearities of semiconductors","date_created":"2023-04-02T14:03:37Z","publisher":"Elsevier","year":"2001","extern":"1","department":[{"_id":"293"}],"series_title":"Semiconductors and Semimetals","user_id":"49063","_id":"43303","status":"public","editor":[{"first_name":"K.T.","full_name":"Tsen, K.T.","last_name":"Tsen"}],"type":"book_chapter","doi":"10.1016/S0080-8784(01)80172-1","main_file_link":[{"url":"https://www.sciencedirect.com/science/article/abs/pii/S0080878401801721"}],"volume":67,"author":[{"first_name":"Torsten","last_name":"Meier","orcid":"0000-0001-8864-2072","full_name":"Meier, Torsten","id":"344"},{"last_name":"Koch","full_name":"Koch, S.W.","first_name":"S.W."}],"date_updated":"2023-04-02T14:05:19Z","page":"231-313","intvolume":"        67","citation":{"apa":"Meier, T., &#38; Koch, S.
