Calcium Rubidium Nitrate: Mode-Coupling Scaling without Factorization
arXiv:cond-mat/0101429 · doi:10.1103/PhysRevE.64.021303
Abstract
The fast dynamics of viscous calcium rubidium nitrate is investigated by depolarized light scattering, neutron scattering and dielectric loss. Fast relaxation evolves as in calcium potassium nitrate. The dynamic susceptibilities can be described by the asymptotic scaling law of mode-coupling theory with a shape parameter ; the temperature dependence of the amplitudes extrapolates to K. However, the frequencies of the minima of the three different spectroscopies never coincide, in conflict with the factorization prediction, indicating that the true asymptotic regime is unreachable.
