Query: Dynamics theory of deformable solids with quasiparticle excitations in
  the presence of electromagnetic fields   A full selfconsistent set of equations is deduced to describe the kinetics
and dynamics of charged quasiparticles (electrons, holes etc.) with arbitrary
dispersion law in crystalline solids subjected to time-varying deformations.
The set proposed unifies the nonlinear elasticity theory equation, a kinetic
equation for quasiparticle excitations and Maxwell's equations supplemented by
the constitute relations. The kinetic equation used is valid for the whole
Brillouin zone. It is compatible with the requirement for periodicity in
k-space and contains an essential new term compared to the traditional form of
the Boltzmann equation. The theory is exact in the frame of the quasiparticle
approach and can be applied to metals, semiconductors, as well as to other
crystalline solids including quantum crystals and low-dimensional lattice
structures.
