Out-of-time-order correlators and quantum chaos

Understand

Quantum Chaos has originally emerged as the field which studies how the properties of classical chaotic systems arise in their quantum counterparts.

• The growing interest in quantum many-body systems, with no obvious classical meaning has led to consider time-dependent quantities that can help to characterize and redefine Quantum Chaos.
• This article reviews the prominent role that the out of time ordered correlator (OTOC) plays to achieve such goal.
