Stochastic resonance in Ising systems.
نویسنده
چکیده
We study by Monte Carlo techniques the evolution of finite two-dimensional Ising systems in oscillating magnetic fields. The phenomenon of stochastic resonance is observed. The characteristic peak obtained for the correlation function between the external field and magnetization, versus the temperature of the system, is studied for various external fields and lattice sizes.

Kinetic Ising System in an Oscillating External Field: Stochastic Resonance and Residence-Time Distributions
Experimental, analytical, and numerical results suggest that the mechanism by which a uniaxial single-domain ferromagnet switches after sudden field reversal depends on the field magnitude and the system size. Here we report new results on how these distinct decay mechanisms influence hysteresis in a two-dimensional nearest-neighbor kinetic Ising model. We present theoretical predictions suppor...
متن کاملSystem size resonance in coupled noisy systems and in the Ising model.
We consider an ensemble of coupled nonlinear noisy oscillators demonstrating in the thermodynamic limit an Ising-type transition. In the ordered phase and for finite ensembles stochastic flips of the mean field are observed with the rate depending on the ensemble size. When a small periodic force acts on the ensemble, the linear response of the system has a maximum at a certain system size, sim...
متن کاملSpatial stochastic resonance in one-dimensional Ising systems.
The one-dimensional Ising model is analytically studied in a spatially periodic and oscillatory external magnetic field using the transfer-matrix method. For low enough magnetic field intensities the correlation between the external magnetic field and the response in magnetization presents a maximum for a given temperature. The phenomenon can be interpreted as a resonance phenomenon induced by ...
متن کاملNon Local Effects in the Sznajd Model: Stochastic resonance aspects
The Sznajd model is basically an Ising spin model, widely used in sociophysics studies as a simple mechanism for predicting decision-making in a closed community through interactions among the nearest neighbors. In the present work we aim to deepen our understanding of this model by analyzing not only local or first neighbor interactions but also long range ones. Besides, we consider the system...
متن کاملStochastic Resonance in 3d Ising Ferromagnets
Finite 3D Ising ferromagnets are studied in periodic magnetic fields both by computer simulations and mean-field theoretical approaches. The phenomenon of stochastic resonance is revealed. The characteristic peak obtained for the correlation function between the external oscillating magnetic field and magnetization versus the temperature of the system, is studied for various external fields and...
