This is either a Galilean boost symmetry or a Lorentzian one and leads to the Navier-Stokes equations or their relativistic counterpart. It is […]

One of these technicalities is that for many […]

We provide a unifi​ed view of assigning a cost to circuits based on the […]

In contrast to the standard method of Shenker […]

AC transport in these models has a few interesting features, which were in […]

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 metals sourced by vorticity, and […]
