Dynamics of phase transition

Langton s tentative answer to the question above is therefore We expect that information processing can emerge spontaneously and come to dominate the dynamics of a physical system in the vicinity of a critical phase transition. Langton speculates that the dynamics of phase transitions is fundamentally equivalent to the dynamics of information processing. 

If a fundamental equivalence between the dynamics of phase transitions and information processing along the lines suggested by Langton really exists, it would also lend support to the Church-l iring hypothesis [lang92] ... 

Ray Kapral came to Toronto from the United States in 1969. His research interests center on theories of rate processes both in systems close to equilibrium, where the goal is the development of a microscopic theory of condensed phase reaction rates,89 and in systems far from chemical equilibrium, where descriptions of the complex spatial and temporal reactive dynamics that these systems exhibit have been developed.90 He and his collaborators have carried out research on the dynamics of phase transitions and critical phenomena, the dynamics of colloidal suspensions, the kinetic theory of chemical reactions in liquids, nonequilibrium statistical mechanics of liquids and mode coupling theory, mechanisms for the onset of chaos in nonlinear dynamical systems, the stochastic theory of chemical rate processes, studies of pattern formation in chemically reacting systems, and the development of molecular dynamics simulation methods for activated chemical rate processes. His recent research activities center on the theory of quantum and classical rate processes in the condensed phase91 and in clusters, and studies of chemical waves and patterns in reacting systems at both the macroscopic and mesoscopic levels. 

Mikihito Takertaka received both the master s degree in engineering in 1988 and the doctor s degree in engineering in 1993 with Prof Takeji Hashimoto from Kyoto Urriversity. In 1997, he was appointed as an assistant professor of the Department of Polymer Chemistry in Kyoto University. He was promoted to associate professor in 2011. His research scope includes the dynamics of phase transitions of polymer alloys and the directed self-assembling of block copolymer thin films. 

Spectroscopic data can also be used to study dynamical aspects, either as proton dynamics deciphered from the AH stretching band profile or as the dynamics of phase transitions. They are helpful in determining the order (first or second), the nature (displacive, order-disorder, reconstructive) and particularly the mechanism of the transformation at the molecular level. This can also shed some light on the conductivity mechanism, which can change considerably in going from one phase to the other. 

However, relatively few studies have addressed the dynamics of phase transitions of lyotropic phases of surfactants and lipids. The superb book The Aqueous Phase Behavior of Surfactants, by R.G. Laughlin, has one chapter dealing with this topic. This chapter is 8 pages long and contains only 25 references, not all dealing with the dynamics of phase transitions, in a book of 558 pages. Likewise, the recent review on the kinetics of phase transitions in surfactant solutions by Egelhaaff includes a rather short... 

In this chapter, studies involving surfactants are somewhat arbitrarily separated from those that concern lipids. Similarities or differences of behavior are pointed out whenever necessary. The chapter is organized as follows. Section II reviews the dynamics of the surfactant Lg phase and of transitions between various lyotropic phases. Section III deals with the dynamics of phase transitions in lipid/water mixtures. Section IV reviews the dynamics of phase transitions induced by shear. Section V concludes this chapter. 

Some aspects of the dynamics of phase transitions are dealt with in this book for amphiphilic block copolymers (Chapter 4, Section VIII), microemulsions (Chapter 5, Sections VII.C (rate of dissolution in microemulsions)) and VII.D (electric field-induced dynamics of microemulsions), and vesicles (Chapter 6, Sections V (phase transitions in vesicle bilayers) and VI (electric field effect on vesicles)).

The FORC method was originally developed to enhance the amoimt of dynamic information extracted from magnetic hysteresis experiments. " We recently proposed that the method can be further developed as an extension of traditional CV to study the dynamics of phase transitions in electrochemical adsorption. ...
