Paper Abstract

Excitonic spectra and certain dynamical features of electron-hole pairs in coupled double-quantum wells under electrical bias are analyzed using numerical data on the evolution of envelope wavefunctions. The excitonic system was described by a two-band effective-mass model. The spectra and their dynamical counterparts were deduced, respectively, from the Fourier transform and the direct time-dependence of the autocorrelation function linking the evolved and initial states. Several measures of quantum dynamics are discussed.
