This paper addresses the question of the stability of a full-employment equilibrium. In particular it examines the notion, recently proposed by Leijonhufvud (1973) that a full-employment equilibrium ...

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.

Statistical mechanics is adept at describing the equilibria of quantum many-body systems. But drive these systems out of equilibrium, and the physics is far from clear. Recent advances have broken ...

A tiny version of this physics toy is revealing quantum secrets Researchers created an atomic-scale version of Newton’s cradle to study thermal equilibrium ...
