The dynamics of the wavepacket is essentially a superposition of ``local Bloch oscillations", whose frequency is proportional to the local slope of the parabolic potential. We show that the amplitude and the phase of the Fourier transform of a signal characterizing this dynamics contains information about the amplitude and the phase of the wavepacket at a given lattice site. Hence, complete reconstruction of the the wavepacket in the real space can be performed from the study of the dynamics of the system.Lire moins >
