Multicomponent Kardar-Parisi-Zhang universality in degenerate coupled condensates

Abstract Gapless phase modes in non-equilibrium condensates fall within the Kardar-Parisi-Zhang (KPZ) universality class, but key single-component symmetries do not clearly generalise to the multicomponent case. We discuss the phase diagram of coupled KPZ equations describing the low-energy theory o...
