Dynamical localisation of conduction electrons in one-dimensional disordered systems

摘要

The phase-space approach based on the Wigner distribution function is applied to the description of dynamics of conduction electrons in finite one-dimensional systems with randomly distributed scattering centres. It is shown that the coherent multiple scattering of the carriers in the disordered environment leads to the slowdown of its dynamics due to the weak localisation. This quantum phenomenon can be treated as a source of the subdiffusion of the quantum particles.
