  These are notes for lectures delivered at the NATO ASI on Dynamics in Leiden,
The Netherlands, in July 1998. The quantum kinetic theory for noninteracting
electrons in a disordered solid is introduced and discussed. We first use
many-body theory to derive the quantum Boltzmann equation that describes
transport and time correlation functions in this system. Particular attention
is paid to the calculation of the electrical conductivity and the density
response function. We then consider corrections to the Boltzmann equation due
to wave interference effects. The disorder expansion of the conductivity is
addressed, and the so-called weak localization or long-time tail contribution
to the conductivity is discussed. We conclude with a brief discussion of the
influence of electron-electron interactions on the properties of disordered
electronic systems.
