Dynamics of zero-energy nonspreading non-Gaussian wave packets for a class of central potentials Original Research Article

Zero-energy wave packets, coherent states, are constructed in such a way that they retain their shape during the time evolution for a large class of central potentials. The packets are not of the Gaussian type with image dependence but, instead, their shape is determined by image with image. A very close quantum–classical correspondence is also shown, i.e., the well localized states travel along suitable classical trajectories.
