Symmetry breaking far from equilibrium
Abstract
An examination of the RayleighBenard convection experiment shows that the defining features of longrange order and spontaneous symmetry breaking as they occur in equilibrium transitions, are also observed far from equilibrium. The broken symmetry is not, as has been suggested, translational invariance, but rather a discrete symmetry under velocity reversal. Some experimental consequences of these observations are outlined.
