A theoretical study of hole wave packets in a GaAs, Als,,Ga,,,As superlattice is presented. Formation of the wave packet by short laser pulse excitation and the time-dependent nature of the wave packet are discussed, with particular attention given to the quasi-periodic nature of the time dependence. Phenomena analogous to those displayed in atomic and molecular wave packet systems are predicte...

Experimental observation of wave-packet propagation in the ion cyclotron range of frequencies in a tokamak plasma is reported. Studies were carried out in the Caltech Research Tokamak [Phys. Fluids 23,614 ( 1980) ] in a pure hydrogen plasma and in a regime where fast-wave damping was sufficiently small to permit multiple toroidal transits of the wave packet. Waves were launched by exciting a sm...

This paper studies the amplitude of large-scale coherent wave-packet structures in jets, modeled by parabolized stability equations (PSEs). Linear PSEs can retrieve shape wave packet...

The numerical prediction, theoretical analysis, and experimental verification of the phenomenon of wave packet revivals in quantum systems has flourished over the last decade and a half. Quantum revivals are characterized by initially localized quantum states which have a short-term, quasi-classical time evolution, which then can spread significantly over several orbits, only to reform later in...
