The Critical Exponent θ ′ in Spin Glasses

چکیده
Short-time dynamic scaling behavior of the 3D ±J Ising spin glass is studied by Monte Carlo methods. Starting the replicas with independent initial configurations with a small pseudo magnetization, the dynamic evolution of the overlap q(t) between two replicas is measured. The initial increase of the overlap q(t) is observed and the corresponding exponent θ ′ is obtained. From the scaling relation λ = d/z − θ ′ , the dynamic exponent z is estimated.

Static chaos and scaling behavior in the spin-glass phase.
We discuss the problem of static chaos in spin glasses. In the case of magnetic field perturbations, we propose a scaling theory for the spin-glass phase. Using the mean-field approach we argue that some pure states are suppressed by the magnetic field and their free energy cost is determined by the finite-temperature fixed point exponents. In this framework, numerical results suggest that mean...
متن کاملMössbauer study of the superspin glass transition in nanogranular Al49Fe30Cu21
The spin-glass-like behavior observed in mechanically alloyed Al49Fe30Cu21 is attributed to the collective freezing of ferromagnetic nanoclusters, i.e., the appearance of a superspin glass phase. The presence of the clusters and their estimated size (;1 nm) were inferred from magnetization measurements. The transition critical exponent zn513.860.4, extracted from ac-susceptibility data, is simi...
متن کاملDynamic critical exponents of the Ising model with multispin interactions
We revisit the short-time dynamics of 2D Ising model with three spin interactions in one direction and estimate the critical exponents z, θ, β and ν. Taking properly into account the symmetry of the Hamiltonian we obtain results completely different from those obtained by Wang et al.. For the dynamic exponent z our result coincides with that of the 4-state Potts model in two dimensions. In addi...
متن کاملPersistence exponent in superantiferromagnetic quenching
We measure the persistence exponent in a phase separating two-dimensional spin system with non-conserved dynamics quenched in a region with four coexisting stripe phases. The system is an Ising model with nearest neighbor, next-to-the-nearest neighbor and plaquette interactions. Due the particular nature of the ground states, the order parameter is defined in terms of blocks of spins. Our estim...
متن کاملOff-Equilibrium Dynamics at Very Low Temperatures in 3d Spin Glasses
We present a high statistic systematic study of the overlap correlation function well below the critical temperature in the three dimensional Gaussian spin glass. The offequilibrium correlation function has been studied confirming the power law behavior for the dynamical correlation length. In particular we have computed the dynamical critical exponent z in a wide range of temperatures, 0.35 ≤ ...
