Description
The last decade has seen significant interest in dissipative hydrodynamical actions in the Schwinger-Keldysh formalism. However there remain very few examples where such actions can be explicitly constructed. I will present a novel prescription that allows, for the first time, one to consistently compute such actions for holographic quantum field theories in general bulk dimension. The explicit construction of such actions allows us to test conjectured relations between hydrodynamical actions and quantum chaos – in particular I will discuss to what extent such actions realise horizon symmetries previously argued for by Knysh, Liu & Pinzani-Fokeeva.
