We present some theoretical concepts that have been used in the study of chemical disspative structures together with a brief description of recent experimental work on Turing patterns and their interaction with travelling waves.

Mode-mode coupling theory is used to obtain the t−52 long time tails for the spin and energy densities autocorrelation functions and the related Kubo integrands for a Heisenberg magnet in the high temperature approximation.

The influence of dipolar forces on the critical dynamics of ferro and antiferomagnets above the critical temperature is considered. The relaxation rates of the spin autocorrelation functions are calculated through the mode-mode coupling approach. They agree with Riedel and Wegner's dynamic...

This paper presents a computer simulation study of a variety of far-from-equilibrium phenomena that can arise in a bistable chemical reaction-diffusion system which also displays Turing and Hopf instabilities. The Turing bifurcation curve and the wave number for the patterns of maximum linear...

The longitudinal fluctuations of the low temperature Heisenberg ferromagnet are studied in the hydrodynamic regime. We mainly analyze the influence on the dynamics of the spontaneous breakdown of the spin rotation symmetry.
