The two-band model is transformed to the exciton representation, and exciton-phonon coupling represented by arbitrary spectral densities is incorporated into the equations of motion for the relevant exciton variables through Redfield superoperators. Time-resolved coherent and incoherent terahertz radiation as well as the incoherent optical fluorescence are calculated for a one-dimensional model of coupled quantum wells in an external electric field with on-site Coulomb interaction between electrons and holes and an overdamped Brownian oscillator spectral density representing the electron-phonon coupling. A doorway-window picture based on the reduced single-electron density matrix is developed for the analysis of both signals. Disorder and phonon-induced dephasing effects on the various signals are discussed and compared."}],"status":"public","date_updated":"2023-04-02T20:06:49Z","publisher":"American Physical Society","volume":60,"author":[{"first_name":"Torsten","full_name":"Meier, Torsten","id":"344","orcid":"0000-0001-8864-2072","last_name":"Meier"},{"first_name":"W.M.","last_name":"Zhang","full_name":"Zhang, W.M."},{"full_name":"Chernyak, V.","last_name":"Chernyak","first_name":"V."},{"full_name":"Mukamel, S.","last_name":"Mukamel","first_name":"S."}],"date_created":"2023-04-02T20:06:46Z","title":"Intraband terahertz emission from coupled semiconductor quantum wells: A model study using the exciton representation","doi":"10.1103/PhysRevB.60.2599","main_file_link":[{"url":"https://journals.aps.org/prb/abstract/10.1103/PhysRevB.60.2599"}],"publication_status":"published","issue":"4","year":"1999","intvolume":"        60","citation":{"short":"T.

The absorption is strongly underestimated for higher energies by the effective mass approximation but good agreement is achieved by using an energy dependent in-plane effective mass. No fitting parameters are used except for a phenomenological broadening. The lineshape of the field-modulated spectra is dominated by the strong field dependence of Wannier–Stark transitions and depends on the amplitude of the modulating field which should be kept small for best results.\r\nREFERENCES"}],"publication":"Applied Physics Letters","main_file_link":[{"url":"https://aip.scitation.org/doi/abs/10.1063/1.122522"}],"doi":"10.1063/1.122522","date_updated":"2023-04-02T21:04:19Z","author":[{"last_name":"Meier","orcid":"0000-0001-8864-2072","id":"344","full_name":"Meier, Torsten","first_name":"Torsten"},{"first_name":"A.","last_name":"Thränhardt","full_name":"Thränhardt, A."},{"first_name":"H.J.","last_name":"Kolbe","full_name":"Kolbe, H.J."},{"last_name":"Hader","full_name":"Hader, J.","first_name":"J."},{"first_name":"G.","last_name":"Weiser","full_name":"Weiser, G."},{"last_name":"Koch","full_name":"Koch, S.W.","first_name":"S.W."}],"volume":73,"citation":{"ama":"Meier T, Thränhardt A, Kolbe HJ, Hader J, Weiser G, Koch SW.
