contents	Memory Effect and Fast Spinodal Decomposition T. Koide G. Krein Rudnei O. Ramos Física, Astronomía y Matemáticas Non Memory effects ion collisions Relativistic heavy equilibrium field dynamics We consider the modification of the Cahn-Hilliard equation when a time delay process through a memoryfunction is taken into account. We then study the process of spinodal decomposition in fast phase transitionsassociated with a conserved order parameter. The introduced memory effect plays an important role to obtain afinite group velocity. Then, we discuss the constraint for the parameters to satisfy causality. The memory effectis seen to affect the dynamics of phase transition at short times and have the effect of delaying, in a significantway, the process of rapid growth of the order parameter that follows a quench into the spinodal region. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437421 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2B Vol.37
