Quantum chaos without false positives
Dmitrii A. Trunin
Out-of-time-order correlators are widely used as an indicator of quantum chaos, but give false-positive quantum Lyapunov exponents for integrable systems with isolated saddle point…

Refined quantum Lyapunov exponents from replica out-of-time-order correlators
Dmitrii A. Trunin
We suggest a new indicator of quantum chaos based on the logarithmic out-of-time-order correlator. On the one hand, this indicator correctly reproduces the average classical Lyapun…
