Abstract

It is shown that the thermal conduction in dielectric glasses at ultralow temperatures is provided by energy transfer over the infinite cluster of resonance pairs of two-level systems. Expressions for the phononless thermal conductivity coefficient (∼T4/3) and for the temperature of crossover between the phonon and phononless mechanisms of thermal conduction are obtained. The possibility of experimental corroboration of the results obtained is discussed.
