SPL - New statistical physics in living matter: non equilibrium states under adaptive control

We consider the low-temperature hydrodynamics of classical spin chains such as the XXZ model and the rotor model. In the XXZ chain, apart from energy and z-magnetization, an extra almost-conserved field emerges at low temperatures. This leads to anomalous transport properties including KPZ scaling of dynamical correlations. The rotor model shows the same phenomenology. These results will be discussed within the framework of fluctuating hydrodynamics.
