We study the growth («coarsening») of domains following a quench from infinite temperature to a temperature T below the ordering transition. The model we consider is an Ising ferromagnet on a square or cubic lattice with weak next-nearest-neighbor antiferromagnetic (AFM) bonds and single-spin-flip dynamics. The AFM bonds introduce free-energy barriers to coarsening and thus greatly slow the dynamics. In two dimensions, the barriers are independent of the characteristic length scale L(t), and…

Kinetics of ferromagnetic ordering in 3D Ising model: how far do we understand the case of a zero temperature quench?
Abstract We study (nonconserved) phase ordering dynamics in the three-dimensional nearest-neighbor Ising model, following rapid quenches from infinite to zero temperature. Results on various aspects,
Phase ordering in 3d disordered systems
We study numerically the phase-ordering kinetics of the site-diluted and bond-diluted Ising models after a quench from an infinite to a low temperature. We show that the speed of growth of the
Slow coarsening in an Ising chain with competing interactions
We investigate the zero-temperature coarsening dynamics of a chain of Ising spins with a nearest-neighbour ferromagnetic and an nth-neighbour antiferromagnetic interactions. For sufficiently large
We investigate the coarsening dynamics of the Ising model on the honeycomb lattice by Monte Carlo simulation. Although the domain growth law and the persistence exponent at nonzero finite temperature
Zero-temperature freezing in the three-dimensional kinetic Ising model.
It is found that domains at long time are highly interpenetrating and topologically complex, with average genus growing algebraically with system size and the long-time state is almost never static, but rather contains "blinker" spins that can flip ad infinitum with no energy cost.
Logarithmic coarsening in the Coulomb glass.
For the nonequilibrium properties studied by us (spatial correlation functions and domain growth laws), it is found that domain growth in the CG is analogous to that in the nearest-neighbor random-field Ising model.
Zero-temperature relaxation of three-dimensional Ising ferromagnets.
This work investigates the properties of the Ising-Glauber model on a periodic cubic lattice of linear dimension L after a quench to zero temperature, finding that for all but the smallest-size systems, the long-time state is almost never static.
Metastability in a four-spin Ising model
Slow dynamics and metastability are often seen in models with quenched disorder, but rather harder to find in situations where no such disorder is present and energy or entropy barriers must be
Anomalous phase-ordering kinetics in the Ising model
Using Monte Carlo simulations we show that for 2D and 3D Ising models at zero temperature the average life-time τ of a square/cubic-like domain of the linear size L is proportional to L2. However,
Ashkin-teller criticality and pseudo-first-order behavior in a frustrated Ising model on the square lattice.
We study the challenging thermal phase transition to stripe order in the frustrated square-lattice Ising model with couplings J(1) < 0 (nearest-neighbor, ferromagnetic) and J(2) > 0 (second-neighbor,
