Fluctuation dissipation ratio in the one dimensional kinetic Ising model

arXiv:cond-mat/0001103 · doi:10.1103/PhysRevE.61.3369

Abstract

The exact relation between the response function and the two time correlation function is derived analytically in the one dimensional kinetic Ising model subjected to a temperature quench. The fluctuation dissipation ratio is found to depend on time through in the time region where scaling holds. The crossover from the nontrivial form to takes place as the waiting time is increased from below to above the equilibration time .
