| Title of the article | Monte-Carlo simulation of the non-equilibrium critical dynamics of the disordered systems with long-range correlated disorder |
| Abstract. | Monte Carlo simulation of the critical behavior of the strong disordered Heisenberg model was carried out. Statical and dynamical exponents were calculated when system started from ordered initial non-equilibrium state. Ageing phenomena and fluctuation-dissipation deviation were investigated. Ageing phenomena developed in two-time dependence of correlation and response functions of «age» of the system tw and observe time t-tw. Research showed that these systems belong to different universality classes, that is, the critical exponents describing the behavior of these systems at a critical point, vary with the concentration of spins. In this paper was implemented the calculation of the autocorrelation function. Found that, in a non-equilibrium behavior of the Heisenberg model with linear defects observed effects of aging. The value obtained in the nonequilibrium regime for a disordered Heisenberg model with linear defects is universal. |
