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 کاملThe topological ordering of covering nodes
The topological ordering algorithm sorts nodes of a directed graph such that the order of the tail of each arc is lower than the order of its head. In this paper, we introduce the notion of covering between nodes of a directed graph. Then, we apply the topological orderingalgorithm on graphs containing the covering nodes. We show that there exists a cut set withforward arcs in these...
متن کاملPhase-ordering kinetics with external fields and biased initial conditions.
The late-time phase-ordering kinetics of the O(n) model for a non-conserved order parameter are considered for the case where the O(n) symmetry is broken by the initial conditions or by an external field. An approximate theoretical approach, based on a ‘gaussian closure’ scheme, is developed, and results are obtained for the time-dependence of the mean order parameter, the pair correlation func...
