We numerically study the relaxation of correlation functions in weakly perturbed integrable XXZ chain. The decay spin-current and energy-current correlations at zero magnetization are well described by single, but quite distinct, rates governed square perturbation strength $g$. However, finite a single function reveals multiple rates. result can be understood terms multi-scale scenario, where v...

Compensation of the poleward eddy heat transport by the heat transport of an eddy-induced mean meridional overturning cell is a common feature in many eddyresolving ocean models. It has been ,argued that this is the result of the weak thermal driving of the ocean. As the actual air/sea coupling is scale dependent, it might be questioned whether the approximation of weak thermal driving is relev...
