Abstract
It is shown that the action of random static elastic and electric fields via electrostrictive interactions can lead to a dynamic glass transition characterized by the change of state from ergodic to non-ergodic. The low-temperature non-ergodic state is characterized by the freezing of an elastic domain-like state with random-phase polar regions with short-range order, not accompanied by structural changes of the lattice. The conditions for a dynamic glass transition are studied in the framework of a self-consistent mode-coupling theory.
