Paper Abstract

Spatial-temporal structure of quantum packet of an electron in an one-dimensional system with impenetrable walls under laser impulse action had been investigated. The coupled equations in partial derivatives for a real and imaginary components of a wave function are solved by the numerical methods. The initial quantum packet is presented in the special trigonometric form with the arbitrary velocity. The calculations of the dynamical variables, its expected values and Fourier-spectra, phase trajectories are performed in details. Influence of a laser impulse duration on the transformation of the initial quantum packet was established. The accurate analytical solutions to the equations in partial derivatives for the free packet at initial trigonometric packet are discussed. These solutions allow us to understand the numerical results of basic part of a paper.
