The early time Lyapunov regime can described by an effective field theory of a single mode, which for maximally chaotic systems […]

The powerful c-theorems, for example, […]

In particular, Takahashi et al managed to create stable spin currents in liquid […]

Thinking of such black holes as quantum circuits, it has been argued […]

These fluids are not amenable to the perturbative methods of Fermi liquid theory, […]

While standard (zero-form) symmetries act on local operators, a […]

I will firstly show how a simple analysis of near-horizon dynamics […]

In this talk, I […]

A fundamental assumption in much subsequent work is the low-temperature dominance of the […]
