Abstract
Numerical solutions are presented for the set of approximated kinetic equations previously obtained to describe the dynamical behaviour of the pseudospin correlation functions of the transverse Ising model in H-bonded ferroelectrics. Stability of the soft mode and spectral characteristics of the correlation functions as T → ∞ are discussed in terms of an interaction made of both nearest-neighbour and dipole-dipole contributions. This infinite-temperature calculation shows how shift (towards zero frequency) and width of the soft mode vary with the interdipolar strength of the interaction. The asymmetry of the imaginary part of susceptibility X″zz(ω) exhibited by KDP in its paraelectric phase is also shown to be due to the dipolar character of the interaction.
