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.

  1. Higher-order discrete time crystals and enhanced sensing in a quantum kicked top

    quant-ph 2025-10 reject novelty 6.0 of 10

    A p=2 kicked-top Floquet system is claimed to host a robust 4-DTC phase at p=π/2, violating the previously proposed q≤p bound for higher-order time crystals.

  2. Quasinormal modes and complexity in saddle-dominated SU(N) spin systems

    hep-th 2025-06 conditional novelty 5.0 of 10

    A family of SU(2) and SU(3) Lipkin-Meshkov-Glick-type Hamiltonians reproduces de Sitter quasinormal-mode densities of states, and late-time probes reveal integrability beneath saddle-dominated scrambling.
