Critical slowing down in an anisotropic ferromagnet
Physics Letters A, 1969Abstract The temperature dependence of the decay rates of the long wavelength spin fluctuations in a ferromagnet with an easy plane of anisotropy is calculated for the upper critical region ( T > T c ). The results are compared with recent measurements made on terbium by Als-Nielsen et al.

Critical slowing down in Ising model for Creutz algorithm
Physica A: Statistical Mechanics and its Applications, 1994Abstract Dynamical critical exponents for the two dimensional Ising model are computed on a cellular automaton from the relaxations of the time displaced correlation and auto-correlation functions for the order parameter and the internal energy at the critical temperatures, and from the nonlinear relaxation time for the order parameter near the ...

On the critical slowing down of spin glasses
Physics Letters A, 1979Abstract Based on the Hartree-Fock density of states, the effective relaxation time of the magnetization in a spin glass is shown to behave like τeff−1∼-(T/Tf− 1)ln(T/Tf−1) near above the freezing temperature Tf.

Critical Slowing Down in One-Dimensional Maps and Beyond
Journal of Statistical Physics, 2005This paper deals with a 1D map of the form \(x_{n+1}=\mu f(x_n)\) where \(\mu\) is a parameter. The author starts with the question: ``Where can one encounter objects with a genuine fractal dimension in the limiting sets of one-dimensional mappings?''. A one-dimensional map has only one Lyapunov exponent \(\lambda\).

On Critical Slowing-Down in Spin Glasses
1980It is rare to find an experimental feature in spin glasses which is both clear-cut and unchanged over a wide variety of materials. The rather simple critical slowing-down of the spin relaxation rates which Salamon and coworkers ‘ have recently identified in the electron spin resonance data from a variety of spin glasses seems to be such a feature.
