WebbA possible proton collective motion in ferroelectric KH2PO4 is studied on the basis of the tunneling model by making use of the statistical mechanics of irreversible processes. The spectrum and the damping constant of this motion are calculated, including their temperature dependence.

Webb1 nov. 1999 · A ferroelectric KH2PO4 crystal is implemented in a simple series connection of an RLC circuit and the transition to chaos near the phase-transition temperature is investigated. The torus-doubling scenario to chaos, the theory of which was expounded by Kaneko for high-dimensional dynamical systems, has been found in the crystal. northern tools texasWebbWe propose a new model for the ferroelectric phase transition of KH2Ø4-type crystals. The proton tunneling mode is found to be strongly coupled with the optical mode of the [K-P041 lattice vibrations along the c -axis via electrostatic Coulomb interaction. northern tools tillersWebbA transition is a process over time and has no end point and includes phases of assimilation and continuous appraisal as people move in, through and out. 1.
