Query: Quantum Chaos and the Correspondence Principle   The correspondence principle is a cornerstone in the entire construction of
quantum mechanics. This principle has been recently challenged by the
observation of an early-time exponential increase of the out-of-time-ordered
correlator (OTOC) in classically non-chaotic systems [E.B. Rozenbaum et al.,
Phys. Rev. Lett. 125, 014101 (2020)], Here we show that the correspondence
principle is restored after a proper treatment of the singular points.
Furthermore our results show that the OTOC maintains its role as a diagnostic
of chaotic dynamics.
