Barrier suppression ionization and wave-packet-spreading models are used to describe to first order in a perturbative expansion the quantum-mechanical interaction between a photodetached electron wave packet and its parent nucleus in the presence of a very strong laser field. The attraction between the wave packet and the nucleus (the first-order approximation to the dipole acceleration) is int...

We examine a group of wave-like cloud patterns that occurred along the coast of Texas on a National Oceanic and Atmospheric Administration satellite advanced very high resolution radiometer IR images taken on January 22, 1999. These wave-like cloud patterns were interpreted to be signatures of a coastal lee wave packet on the basis of simultaneous field observations and theories developed by Zh...

We consider a thought experiment, in which a neutrino is produced by an electron on a nucleus in a crystal. The wave function of the oscillating neutrino is calculated assuming that the electron is described by a wave packet. If the electron is relativistic and the spatial size of its wave packet is much larger than the size of the crystal cell, then the wave packet of the produced neutrino has...

Starting from a model study of the collinear (H, H2) exchange reaction in 1959, time-dependent quantum mechanical wave packet (TDQMWP) method has come long way dealing with systems as large Cl + CH4.

The geometrical phase of a time-dependent singular oscillator is obtained in the framework of Gaussian wave packet. It is shown by a simple geometrical approach that the geometrical phase is connected to the classical nonadiabatic Hannay angle of the generalized Harmonic oscillator. Explicitly time-dependent problems present special difficulties in classical and quantum mechanics. However, they...
