Query: Regenesis and quantum traversable wormholes   Recent gravity discussions of a traversable wormhole indicate that in
holographic systems signals generated by a source could reappear long after
they have dissipated, with the need of only performing some simple operations.
In this paper we argue the phenomenon, to which we refer as "regenesis", is
universal in general quantum chaotic many-body systems, and elucidate its
underlying physics. The essential elements behind the phenomenon are: (i)
scrambling which in a chaotic system makes out-of-time-ordered correlation
functions (OTOCs) vanish at large times; (ii) the entanglement structure of the
state of the system. The latter aspect also implies that the regenesis
phenomenon requires fine tuning of the initial state. Compared to other
manifestations of quantum chaos such as the initial growth of OTOCs which deals
with early times, and a random matrix-type energy spectrum which reflects very
large time behavior, regenesis concerns with intermediate times, of order the
scrambling time of a system. We also study the phenomenon in detail in general
two-dimensional conformal field theories in the large central charge limit, and
highlight some interesting features including a resonant enhancement of
regenesis signals near the scrambling time and their oscillations in coupling.
Finally, we discuss gravity implications of the phenomenon for systems with a
gravity dual, arguing that there exist regimes for which traversability of a
wormhole is quantum in nature, i.e. cannot be associated with a semi-classical
spacetime causal structure.
