Competing Glauber and Kawasaki Dynamics
Using a quantum formulation of the master equation we study a kinetic Ising model with competing stochastic processes: the Glauber dynamics with probability p and the Kawasaki dynamics with probability 1− p. Introducing explicitely the coupling to a heat bath and the mutual static interaction of the spins the model can be traced back exactly to a Ginzburg Landau functional when the interaction ...
متن کاملSmall-world network effect in competing Glauber- and Kawasaki-type dynamics
In this article, we investigate the competing Glauber-type and Kawasaki-type dynamics with small-world network (SWN) effect, in the framework of the Gaussian model. The Glauber-type single-spin transition mechanism with probability p simulates the contact of the system with a heat bath and the Kawasaki-type dynamics with probability 1 − p simulates an external energy flux. Two different types o...
متن کاملDamage spreading in two-dimensional trivalent cellular structures with competing Glauber and Kawasaki dynamics.
The damage spreading of the Ising model on several two-dimensional trivalent structures, including soap froth, Voronoi, and hierarchical structures, are studied with competing Glauber and Kawasaki dynamics. The damage spreading transition temperature T(d) and the Curie temperature T(C) of these structures are compared. We find that T(d) of the hierarchical lattices decreases sharply as the prob...
متن کاملInterfaces in confined Ising models: Kawasaki, Glauber and sheared dynamics
We study interfacial properties of the phase-separated two-dimensional Ising model. The interface between coexisting phases is stabilized by two parallel walls with opposing surface fields. A driving field parallel to the walls is applied which (i) either acts locally at the walls or (ii) varies linearly with distance across the strip. Using computer simulations with Kawasaki dynamics, we found...
متن کاملLow-temperature Glauber dynamics under weak competing interactions.
We consider the low but nonzero-temperature regimes of the Glauber dynamics in a chain of Ising spins with first- and second-neighbor interactions J1,J2. For 0<-J2/|J1|<1 it is known that at T=0 the dynamics is both metastable and noncoarsening, while being always ergodic and coarsening in the limit of T→0+. Based on finite-size scaling analyses of relaxation times, here we argue that in that l...
