The approach has been used for the analysis of various processes related to the Bloch-oscillation dynamics of carriers in static fields and for investigating dynamical localization induced by alternating fields. It is shown that the theory describes very well experimental field-modulated absorption spectra of a strongly coupled superlattice. Furthermore, characteristic signatures, such as negative absorption in the short-pulse optical response of superlattices subjected simultaneously to static and alternating electric fields are predicted.}}, author = {{Meier, Torsten and Kolbe, H.J. and Thränhardt, A. and Weiser, G. and Thomas, P. and Koch, S.W.}}, journal = {{Physica E: Low-dimensional Systems and Nanostructures}}, number = {{1-2}}, pages = {{267--273 }}, publisher = {{North-Holland}}, title = {{{Coherent dynamics of photoexcited semiconductor superlattices in homogeneous electric fields}}}, doi = {{10.1016/S1386-9477(99)00274-X}}, volume = {{7}}, year = {{2000}}, } @article{43310, abstract = {{Local ultrafast optical excitation of electron–hole pairs in disordered semiconductors provides the possibility to observe experimentally interaction-assisted propagation of correlated quantum particles in a disordered environment.
