We review recent developments encompassing the description of quantum chaos in holography. We discuss the characterization of quantum chaos based on the late time vanishing of out-of-time-order correlators and explain how this is realized in the dual gravitational description. We also review the connections of chaos with the spreading of quantum entanglement and diffusion phenomena.

Towards the Web of Quantum Chaos Diagnostics
Haar-averaged higher-point out-of-time-order correlators equal multi-fold Loschmidt echoes, and complexity is conjectured to satisfy C^2 ~ -log LE.

OTOC and Quamtum Chaos of Interacting Scalar Fields
Discretized λφ⁴ theory yields thermal OTOC with exponential growth and Lyapunov exponent scaling as T^{1/4}, showing quantum chaos signatures at low perturbative orders in the oscillator chain.

Traversable wormhole with double trace deformations via gravitational shear and sound channels
Double trace deformations create traversable wormholes in AdS5 black branes via gravitational shear and sound channel perturbations that violate ANEC in the hydrodynamic limit.

Higher-Order Krylov State Complexity in Random Matrix Quenches
Higher-order generalized spread complexities show a more pronounced pre-equilibration peak than standard spread complexity in random matrix quenches, quantifying chaos more sharply up to third order.

Interplay of magnetic field and chemical potential induced anisotropy and frame dependent chaos of a $Q\bar{Q}$ pair in holographic QCD
In a holographic QCD model, chaotic string dynamics appear only for unstable configurations near the horizon, and magnetic field and chemical potential affect chaos oppositely in string and Einstein frames.

Chaos in hyperscaling violating Lifshitz theories
For charged hyperscaling-violating Lifshitz theories, the butterfly velocity is derived via shockwave and entanglement wedge methods, rewritten in entropy and charge per central charge, and shown to be non-monotonic i...

Charged Black Hole with String Cloud Deformation: Entanglement and Chaos
In a charged AdS black hole with a string cloud, entanglement entropy and entanglement wedge cross-section increase with charge and backreaction, while mutual information and butterfly velocity decrease with charge.

Comparative study of the butterfly velocity in holographic QCD models at finite temperature and chemical potential
Using three independent holographic methods, the authors obtain matching butterfly velocities for four QCD-like models and find a universal increase with temperature and decrease with chemical potential.
