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.

A quantum theoretical description of photoemission by a single laser-driven electron wave packet is presented. Energy-momentum conservation ensures that the partial emissions from individual momentum components of the electron wave packet do not interfere when the driving field is unidirectional. In other words, light scattering by an electron packet is independent of the phases of the pure mom...

Resonant transmission occurs when constructive interference results in the complete passage of an incoming wave through array barriers. In this paper we explore such a scenario with one dimensional models. We adopt packets finite width to illustrate deterioration resonance decreasing packet width, and suggest approximate function for transmitted reflected components, derived from aspects both p...

The frequency and direction dependence of transmission coefficients at interfaces was investigated theoretically. The interfaces are formed by having two Lennard-Jones materials differing in mass and interatomic potential equally divided at the center of an fcc lattice system. A single frequency wave-packet is generated at one end of the system and allowed to propagate through the system until ...
