The signatures of two-exciton resonances are incorporated through the exciton scattering matrix, totally avoiding the explicit calculation of two-exciton states. Exact expressions for the nonlinear optical response of two-dimensional semiconductor nanostructures in a strong perpendicular magnetic field are derived by truncating at the n=1 Landau level, and using the symmetry of the system and a group-theoretical analysis. We find that the nonlinear optical response depends crucially on asymmetries between particle-particle and particle-hole Coulomb interactions."}],"extern":"1","date_created":"2023-04-02T20:49:32Z","type":"journal_article","department":[{"_id":"293"}],"year":"1998","title":"Effective Frenkel Hamiltonian for optical nonlinearities in semiconductors: Application to magnetoexcitons","author":[{"full_name":"Meier, Torsten","first_name":"Torsten","last_name":"Meier","orcid":"0000-0001-8864-2072","id":"344"},{"first_name":"V.","last_name":"Chernyak","full_name":"Chernyak, V."},{"last_name":"Yokojima","first_name":"S.","full_name":"Yokojima, S."},{"last_name":"Mukamel","first_name":"S.","full_name":"Mukamel, S."}],"date_updated":"2023-04-02T20:49:34Z","publication_status":"published","intvolume":"        58","main_file_link":[{"url":"https://journals.aps.org/prb/abstract/10.1103/PhysRevB.58.4496"}],"language":[{"iso":"eng"}],"doi":"10.1103/PhysRevB.58.4496"},{"citation":{"ieee":"T.

In semiconductor superlattices, evidence for phase conservation on scattering was obtained when time-resolved THz-emission experiments indicated that the dephasing of the probed intraband coherence may proceed slower than the relaxation of carriers via emission of LO-phonons estimated to occur on a 200-fs time scale as in bulk GaAs.1 To corroborate this interpretation, the unknown LO-phonon emission times in the superlattices must be measured for the experimental conditions of the THz-emission experiments. In this paper, a combined investigation of the coherent and incoherent dynamics of optically excited charge carriers in a superlattice structure is presented. A comparison of the characteristic time constants provides clear evidence for the conservation of the phase of the intraband coherence on LO-phonon relaxation.","lang":"eng"}],"publication":"Quantum Electronics and Laser Science Conference","language":[{"iso":"eng"}],"article_number":"QTuE16","main_file_link":[{"url":"https://opg.optica.org/abstract.cfm?uri=qels-1997-QTuE16"}],"publication_status":"published","date_updated":"2023-05-01T10:55:25Z","author":[{"id":"344","full_name":"Meier, Torsten","first_name":"Torsten","last_name":"Meier","orcid":"0000-0001-8864-2072"},{"last_name":"Wolter","first_name":"F.","full_name":"Wolter, F."},{"last_name":"Roskos","first_name":"H.G.","full_name":"Roskos, H.G."},{"last_name":"Je","first_name":"K.-C","full_name":"Je, K.-C"},{"first_name":"J.","last_name":"Hader","full_name":"Hader, J."},{"full_name":"Rossi, F.","first_name":"F.","last_name":"Rossi"},{"full_name":"Köhler, K.","last_name":"Köhler","first_name":"K."},{"last_name":"Koch","first_name":"S.W.","full_name":"Koch, S.W."},{"first_name":"H.","last_name":"Kurz","full_name":"Kurz, H."}],"publication_identifier":{"isbn":["1-55752-501-3"]},"title":"Conservation of intraband coherence upon carrier relaxation by LO-phonon emission","year":"1997"}]
