Abstract We study the contour dependence of the out-of-time-ordered correlation function (OTOC) both in weakly coupled field theory and in the Sachdev-Ye-Kitaev (SYK) model. We show that its value, including its Lyapunov spectrum, depends sensitively

The Planckian relaxation rate $\ensuremath{\hbar}/{t}_{\mathrm{P}}=2\ensuremath{\pi}{k}_{\mathrm{B}}T$ sets a characteristic timescale for both the equilibration of quantum critical systems and maximal quantum chaos. In this Rapid Communication, we s

For perturbative scalar field theories, the late-time-limit of the out-of-time-ordered correlation function that measures (quantum) chaos is shown to be equal to a Boltzmann-type kinetic equation that measures the total gross (instead of net) particl

We argue that the gravitational shock wave computation used to extract the scrambling rate in strongly coupled quantum theories with a holographic dual is directly related to probing the system's hydrodynamic sound modes. The information recovered fr

We propose a modified gravitational action containing besides the Einstein–Cartan term some quadratic contributions resembling the Yang–Mills Lagrangian for the Lorentz spin connections. We outline how a propagating torsion arises and we solve ex
