Dynamic Phase Transition and Hysteresis in Kinetic Ising Models
We briefly introduce hysteresis in spatially extended systems and the dynamic phase transition observed as the frequency of the oscillating field increases beyond a critical value. Hysteresis and the decay of metastable phases are closely related phenomena, and a dynamic phase transition can occur only for field amplitudes, temperatures, and system sizes at which the metastable phase decays thr...
متن کاملKinetic Phase Transition in the Mixed-Spin Ising Model
In this work we studied a ferromagnetic mixed-spin Ising model including a single ion crystal-field term. The model system consists of two interpenetrating sublattices with spins σ = 1/2 and S = 1. The spins σ = 1/2 occupy the sites of one sublattice, their nearest-neighbours are spins S on the other sublattice, and vice versa. The system is in contact with a heat bath, the spins flipping accor...
متن کاملKinetic Ising model in an oscillating field : Finite - size scaling at the dynamic phase transition
We study hysteresis for a two-dimensional, spin-1/2, nearest-neighbor, kinetic Ising ferromagnet in an oscillating field, using Monte Carlo simulations. The period-averaged magnetization is the order parameter for a proposed dynamic phase transition (DPT). To quantify the nature of this transition, we present the first finite-size scaling study of the DPT for this model. Evidence of a diverging...
متن کاملHysteretic nonequilibrium Ising-Bloch transition.
We show that a parametrically driven cubic-quintic complex Ginzburg-Landau equation exhibits a hysteretic nonequilibrium Ising-Bloch transition for large enough quintic nonlinearity. These results help to understand the recent experimental observation of this phenomenon [A. Esteban-Martín, Phys. Rev. Lett. 94, 223903 (2005)].

These are lecture notes for a talk based on “An Introduction to the Ising Model” by Barry Cipra. Available at http://www.maa.org/programs/ maa-awards/writing-awards/an-introduction-to-the-ising-model. Some of the notation has been changed from the paper for clarity.
