A new study has uncovered the universal dynamics far from equilibrium in randomly interacting spin models, thereby complementing the well-established universality in low-energy equilibrium physics.

(Phys.org)—In 1876, the Austrian physicist Ludwig Boltzmann noticed something surprising about his equations that describe the flow of heat in a gas. Usually, the colliding gas particles eventually ...

Systems out of thermodynamic equilibrium are very common in nature. In recent years they have attracted constantly growing attention because of their relevance for fundamental physics as well as for ...

The qualitative success of the nearest-neighbour spin-ice model also shows that the avalanche quench has realized intrinsic non-equilibrium behaviour in spin ice. Although extrinsic defects can ...

Three different papers by three different groups on the same theme back-to-back in Nature? That is unusual. Yes, which is why they caught my eye. The papers all look rather interesting: they are about ...

How it works: the wave in the foreground is an illustration of the phase of an out-of-equilibrium Bose-Einstein condensate in a 1D cavity, which belongs to the Kardar-Parisi-Zhang universality class.
