abstract
We consider a real massive free quantum scalar field with arbitrary curvature coupling on $n$-dimensional anti-de Sitter space-time. We use Hadamard renormalization to find the vacuum expectation values of the quadratic field fluctuations and the stress-energy tensor, presenting explicit results for $n=2$ to $n=11$ inclusive.

Superluminal chaos after a quantum quench
In BTZ-Vaidya holographic quenches, out-of-time-order correlators imply a transient superluminal butterfly velocity v_B = r_+/r_- > 1 while Lyapunov growth saturates the chaos bounds set by the local temperatures.
