Temperature chaos is present in off-equilibrium spin-glass dynamics

We find a dynamic effect in the non-equilibrium dynamics of spin glass that closely parallels equilibrium temperature chaos. This effect, we name chaos, is spatially heterogeneous to large degree. The key controlling quantity time-growing spin-glass coherence length. Our detailed characterization chaos paves way for analysis recent and forthcoming experiments. work has been made possible thanks most massive simulation date dynamics, carried out on Janus~II custom-built supercomputer.
