Understanding and classifying non-equilibrium many-body phenomena, analogously to the classification of equilibrium states of matter into universality classes 1 , 2 , is an outstanding problem in physics. From stellar matter to financial markets, any many-body system can be out of equilibrium in a myriad of ways, and many are difficult to experiment on. It is therefore a major goal to establish universal principles that apply to different phenomena and physical systems. For equilibrium states… Expand

Observation of universal dynamics in a spinor Bose gas far from equilibrium
This work observes the emergence of universal dynamics far from equilibrium by evaluating spatially resolved spin correlations in a quasi-one-dimensional spinor Bose–Einstein condensate, and establishes an important class of non-stationary systems whose dynamics is encoded in time-independent scaling exponents and functions, signalling the existence ofnon-thermal fixed points.
