The oscillation amplitude is comparable to the flux values for the short pulses, duration of which \\gamma_l^{-1} \\leq \\hbar/\\Delta E. A damping echo of the exciting pulse appears through the time intervals 2\\pi\\hbar/\\Delta E in the case of the very short light pulses \\gamma_l^{-1}\\ll \\hbar/\\Delta E. Symmetrical and asymmetrical pulses with a sharp front have been considered. Our theory is applicable for the narrow QWs in a strong magnetic field, when the equidistant energy levels correspond to the electron-hole pairs with different Landau quantum numbers.", "revisions": [ { "version": "v2", "updated": "2000-09-09T16:08:21.000Z" } ], "analyses": { "keywords": [ "strong magnetic field", "absorption", "equidistant energy levels correspond", "reflection" ], "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2000cond.mat..4178K" } } }
