,The Elastic Properties of Crystals with Jahn—Teller Structural Phase Transitions,ing. In this chapter we discuss the main types of conceptually different situations produced by the cooperative Jahn—Teller effect and examine the elastic anomalies accompanying this structural phase transition.

,Jahn—Teller Crystals in External Fields: Phase Diagrams and Properties,ls by these fields are also not too large. The most pronounced changes of the crystal properties occur specifically in this case when splittings of electron levels by external fields turn out to be of the same order as those produced by the molecular field.

,The Jahn—Teller Effect,always associated with the existence of some symmetry element. The three . functions of the hydrogen atom serve as an example. Their degeneracy is due to the fact that such a system has spherical symmetry: Rotation about any axis through the nucleus leaves the Hamiltonian invariant, while transformi

,The Elastic Properties of Crystals with Jahn—Teller Structural Phase Transitions,te states of different Jahn—Teller sites interact. We have shown that interstitial interaction makes the ground state of the crystal correspond to a certain packing of “frozen” (in contrast with the case of an isolated center) local Jahn—Teller distortions. With increasing temperature the correlatio
