Query: Slow scrambling in sonic black holes   We study from the perspective of quantum information scrambling an acoustic
black hole modelled by two semi-infinite, stationary, one dimensional
condensates, connected by a spatial step-like discontinuity, and flowing
respectively at subsonic and supersonic velocities. We develop a simple
analytical treatment based on Bogolyubov theory of quantum fluctuations which
is sufficient to derive analogue Hawking emission, and we compute out-of-time
order correlations (OTOCs) of the Bose density field. We find that sonic black
holes are slow scramblers contrary to their astrophysical counterparts: this
manifests in a power law growth $\propto t^2$ of OTOCs in contrast to the
exponential increase in time expected for fast scramblers.
