Quantum chaos in the perfect fluid: spectrum of initial fluctuations in the little bang

Abstract

We outline how unstable quantum fluctuations decohere classical fields in heavy ion collisions, leading to an equation of state and hydrodynamics. Explicit numerical realization of this framework in a scalar ${\varphi }^4$ theory demonstrates that anomalously low values of $\eta /s$ can be generated.
