This time-asymmetry is characteristic of non-equilibrium systems as it can only be displayed by systems in which energy dissipation takes place18. In the case of symmetric connections and static parameters, the model converges to an equilibrium stationary state. Consequently, it is a generalization ...
18 Therefore, you can imagine that many hard problems in the real world can be solved through the Ising model.13,21 In order to implement the cost function described in Eq. (7) as the effective loss of the DOPO network, pairs of DOPOs must be coupled with the coupling constant J ij ...
We study the qualitative and quantitative properties of the Barkhausen noise emerging at finite temperatures in random Ising models. The random-bond Ising Model is studied with a Wolff cluster Monte-Carlo algorithm to monitor the avalanches generated by an external driving magnetic field. Satisfactory ...
In the stationary states of the model, which are the counterparts of the Ising equilibrium states, the fluctuation-dissipation theorem breaks down due to the lack of time reversal invariance. In the nonstationary phase-ordering kinetics, the parametric plot of the integrated response function χ(t...

In the following we consider the d = 1 Ising model with Hamiltonian H[σ i ] = −J Ni=1 σ i σ i+1 − Ni=1 h i σ i (13) where J > 0 is the ferromagnetic coupling and h i =±h 0 is an uncorrelated random field with expectationsE ...
anti-ferromagnetic Ising model on a triangular lattice [14] (AFIT). 3 2 Dynamical exponent of the FFIM We now consider the dynamical properties of the FFIM at equilibrium at its critical temperature T c = 0. The system is initially thermalized and then evolves with the Glauber dynamics [...
