Critical Fluctuation Operators for a Quantum Model of Ferroelectric
A. Car, V. A. Zagrebnov
Abstract
We consider dependence of the critical fluctuation operators on the rate of interaction decay for an exactly soluble model of the quantum anharmonic crystal of ferroelectric type. The critical exponents for the abnormal behavior of the displacement and momentum fluctuation operators on the critical line are calculated explicitly.
