Nonequilibrium steady state of the kinetic Glauber-Ising model under an alternating magnetic field.

چکیده
When periodically driven by an external magnetic field, a spin system can enter a phase of steady entrained oscillations with nonequilibrium probability distribution function. We consider an arbitrary magnetic field switching its direction with frequency comparable with the spin-flip rate and show that the resulting nonequilibrium probability distribution can be related to the system equilibrium distribution in the presence of a constant magnetic field of the same magnitude. We derive convenient approximate expressions for this exact relation and discuss their implications.

Dynamic phase transition in the two-dimensional kinetic Ising model in an oscillating field: universality with respect to the stochastic dynamics.
We study the dynamical response of a two-dimensional Ising model subject to a square-wave oscillating external field. In contrast to earlier studies, the system evolves under a so-called soft Glauber dynamic [Rikvold and Kolesik, J. Phys. A 35, L117 (2002)], for which both nucleation and interface propagation are slower and the interfaces smoother than for the standard Glauber dynamic. We choos...

A family of nonequilibrium kinetic Ising models, introduced earlier, evolving under the competing effect of spin flips at zero temperature and nearest neighbour random spin exchanges is further investigated here. By increasing the range of spin exchanges and/or their strength the nature of the phase transition 'Ising-to-active' becomes of (dynamic) mean-field type and a first order tricitical p...
متن کاملDynamic phase transitions and dynamic phase diagrams in the kinetic mixed spin-1 and spin-2 Ising system in an oscillating magnetic field*
In recent years, several theoretical studies on the equilibrium properties of two sublattice mixed spin-1 and spin-2 Ising model have been reported [1]. Nonequlibrium properties of this model has not been investigated so far. One of the interesting problems in nonequlibrium systems is to calculate the dynamic phase transition (DPT) temperatures and present the dynamic phase diagrams. In this wo...
متن کاملNonequilibrium Steady State in a Quantum System: One-Dimensional Transverse Ising Model with Energy Current
We study the nonequilibrium steady states of an Ising chain in a transverse field h by investigating the effect of a field l, which drives the current of energy. The zero-temperature, h-l phase diagram is determined exactly, and it is found that the energy current appears continuously above a threshold l . lcshd. The long-range magnetic order (present for h , hc , l , lc) is destroyed in the cu...
متن کاملOne-dimensional nonequilibrium kinetic Ising models with branching annihilating random walk
Nonequilibrium kinetic Ising models evolving under the competing effect of spin flips at zero temperature and nearest neighbour spin exchanges at T = ∞ are investigated numerically from the point of view of a phase transition. Branching annihilating random walk of the ferromagnetic domain boundaries determines the steady state of the system for a range of parameters of the model. Critical expon...
