The Boltzmann-equation description of transport in superconductors

Abstract
The purpose of the present review article is to give an outline of a quasiclassical approach to the description of transport in superconductors. The Boltzmann equation for normal excitation in a superconductor is formulated and its various properties are discussed and a full set of equations to describe condensate dynamics in the presence of external fields is given. Applications of this approach are demonstrated with a number of examples.
