SIMULTANEOUS CONDENSATION OF SEVERAL MODES AT STRUCTURAL PHASE TRANSITIONS

Abstract
The structural transitions in a number of materials has been explained by the simultanous condensation of several modes at the transition temperature. The various types of couplings between the order-parameters corresponding to this mechanism are discussed.
