Energy flux distribution in a two-temperature Ising model

The nonequilibrium steady state of an infinite-range Ising model is studied. The steady state is obtained by dividing the spins into two groups and attaching them to two heat baths generating spin flips at different temperatures. In the thermodynamic limit, the resulting dynamics can be solved exactly, and the probability flow in the phase space can be visualized. We can calculate the steady st...

VI.G Exact free energy of the Square Lattice Ising model

As indicated in eq.(VI.35), the Ising partition function is related to a sum S, over collections of paths on the lattice. The allowed graphs for a square lattice have 2 or 4 bonds per site. Each bond can appear only once in each graph, contributing a factor of t ≡ tanhK. While it is tempting to replace S with the exactly calculable sum S ′ , of all phantom loops of random walks on the lattice, ...

Zero-temperature freezing in the three-dimensional kinetic Ising model.

We investigate the relaxation of the Ising-Glauber model on a periodic cubic lattice after a quench to zero temperature. In contrast to the conventional picture from phase-ordering kinetics, we find the following: (i) domains at long time are highly interpenetrating and topologically complex, with average genus growing algebraically with system size; (ii) the long-time state is almost never sta...

Large-scale Simulation of the Two-dimensional Kinetic Ising Model

We present Monte Carlo simulation results for the dynamical critical exponent z of the two-dimensional kinetic Ising model using a lattice of size 106×106 spins. We used Glauber as well as Metropolis dynamics. The z-value of 2.16± 0.005 was calculated from the magnetization and energy relaxation from an ordered state towards the equilibrium state at Tc. submitted to Physica A ∗ [email protected]...

kinetic energy model of two-phase debris flow

a numerical model for two-phase debris flows is developed in this paper, on the basis of understanding of the physical characteristics of debris flows from field investigations and experiments. employing a moving coordinate, the kinetic energy equation of gravel particles in unit volume in debris flow is developed by considering the potential energy of the particles, energy from the liquid phas...
