An experiment-oriented analysis of 2D spin-glass dynamics: A twelve time-decades scaling study [link]Paper  doi  abstract   bibtex   
Recent high precision experimental results on spin-glass films ask for a detailed understanding of the domain-growth dynamics of two-dimensional spin glasses. To achieve this goal, we numerically simulate the out-equilibrium dynamics of the Ising spin glass for a time that spans close to twelve orders of magnitude (from picoseconds to order of a second), in systems large enough to avoid finite-size effects. We find that the time-growth of the size of the glassy domains is excellently described by a single scaling function. A single time-scale τ (T) controls the dynamics. τ (T) diverges upon approaching the T = 0 critical point. The divergence of τ (T → 0) is Arrhenius-like, with a barrier height that depends very mildly on temperature. The growth of this barrier-height is best described by critical dynamics. As a side product we obtain an impressive confirmation of universality of the equilibrium behavior of two-dimensional spin-glasses. © 2019 IOP Publishing Ltd.
