Recent Developments in the Holographic Description of Quantum Chaos
Advances in High Energy Physics, 2019 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 ...

Nonlinear dynamics and quantum chaos of a family of kicked p-spin models. [PDF]
Physical Review E, 2021 We introduce kicked p-spin models describing a family of transverse Ising-like models for an ensemble of spin-1/2 particles with all-to-all p-body interaction terms occurring periodically in time as delta-kicks.

Chaos and high temperature pure state thermalization
Journal of High Energy Physics, 2019 Classical arguments for thermalization of isolated systems do not apply in a straightforward way to the quantum case. Recently, there has been interest in diagnostics of quantum chaos in many-body systems.

Quantum chaos in triangular billiards [PDF]
Physical Review Research, 2021 We present an extensive numerical study of spectral statistics and eigenfunctions of quantized triangular billiards. We compute two million consecutive eigenvalues for six representative cases of triangular billiards, three with generic angles with ...

Interacting bosons in a triple well: Preface of many-body quantum chaos. [PDF]
Physical Review E, 2021 Systems of interacting bosons in triple-well potentials are of significant theoretical and experimental interest. They are explored in contexts that range from quantum phase transitions and quantum dynamics to semiclassical analysis.

Chaos and quantum chaos in cosmological models [PDF]
Chaos, Solitons & Fractals, 1995 Spatially homogeneous cosmological models reduce to Hamiltonian systems in a low dimensional Minkowskian space moving on the total energy shell $H=0$. Close to the initial singularity some models (those of Bianchi type VIII and IX) can be reduced further, in a certain approximation, to a non-compact triangular billiard on a 2-dimensional space of ...

Quantum Particle Swarm Optimization Extraction Algorithm Based on Quantum Chaos Encryption
Complexity, 2021 Considering the highly complex structure of quantum chaos and the nonstationary characteristics of speech signals, this paper proposes a quantum chaotic encryption and quantum particle swarm extraction method based on an underdetermined model.

Communications in Mathematical Sciences, 2018 We study the notion of quantum Kac's chaos which was implicitly introduced by Spohn and explicitly formulated by Gottlieb. We prove the analogue of a result of Sznitman which gives the equivalence of Kac's chaos to 2-chaoticity and to convergence of empirical measures.

Avoiding quantum chaos in quantum computation [PDF]
Physical Review E, 2001 We study a one-dimensional chain of nuclear $1/2-$spins in an external time-dependent magnetic field. This model is considered as a possible candidate for experimental realization of quantum computation. According to the general theory of interacting particles, one of the most dangerous effects is quantum chaos which can destroy the stability of ...

Generalized spectral form factors and the statistics of heavy operators
Journal of High Energy Physics, 2022 The spectral form factor is a powerful probe of quantum chaos that diagnoses the statistics of energy levels, but is blind to other features of a theory such as matrix elements of operators or OPE coefficients in conformal field theories.
