Query: The Long Range Interaction and the Relaxation in Glasses at Low
  Temperatures   We describe the interaction stimulated relaxation in the ensemble of
two-level systems, responsible for low temperature kinetics and thermodynamics
properties of amorphous solids. This relaxation gets significant at
sufficiently low temperature when phonons are substantially frozen out. We show
that in the realistic experimental situation the measuring field strongly
accelerates the interaction stimulated relaxation. The characteristic
temperature and field dependences of the relaxation rate are found when the
rate is affected both by the interaction between two level systems and by the
external field.
