Theory of Phase Ordering Kinetics
The theory of phase ordering dynamics – the growth of order through domain coarsening when a system is quenched from the homogeneous phase into a brokensymmetry phase – is reviewed, with the emphasis on recent developments. Interest will focus on the scaling regime that develops at long times after the quench. How can one determine the growth laws that describe the time-dependence of characteri...
متن کاملPhase-ordering kinetics on graphs.
We study numerically the phase-ordering kinetics following a temperature quench of the Ising model with single spin-flip dynamics on a class of graphs, including geometrical fractals and random fractals, such as the percolation cluster. For each structure we discuss the scaling properties and compute the dynamical exponents. We show that the exponent a_{chi} for the integrated response function...
متن کاملPhase ordering kinetics of the Bose gas.
We study the approach to equilibrium of a Bose gas to a superfluid state. We point out that dynamic scaling, characteristic of far from equilibrium phase-ordering systems, should hold. We stress the importance of a nondissipative Josephson precession term in driving the system to a new universality class. A model of coarsening in dimension d52, involving a quench between two temperatures below ...
متن کاملPhase ordering kinetics of a nonequilibrium exciton-polariton condensate
We investigate the process of coarsening via annihilation of vortex-antivortex pairs, following the quench to the condensate phase in a nonresonantly pumped polariton system. We find that the late-time dynamics is an example of universal phase-ordering kinetics, characterized by scaling of correlation functions in time. Depending on the parameters of the system, the evolution of the characteris...
متن کاملKinetics of Phase ordering in Microemulsions and Micellar Solutions
The “head” part of surfactant molecules consist of a polar or ionic group. The “tail” of many surfactants consist of a single hydrocarbon chain whereas that of some other surfactants, e.g., phospholipids, are made of two hydrocarbon chains both of which are connected to the same head. In contrast, gemini surfactants2–5, consist of two single-chain surfactants whose heads are connected by a “spa...
