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.

Many-body Quantum Chaos and Entanglement in a Quantum Ratchet [PDF]
, 2017 We uncover signatures of quantum chaos in the many-body dynamics of a Bose-Einstein condensate-based quantum ratchet in a toroidal trap. We propose measures including entanglement, condensate depletion, and spreading over a fixed basis in many-body ...

Spread and spectral complexity in quantum spin chains: from integrability to chaos [PDF]
Journal of High Energy PhysicsWe explore spread and spectral complexity in quantum systems that exhibit a transition from integrability to chaos, namely the mixed-field Ising model and the next-to-nearest-neighbor deformation of the Heisenberg XXZ spin chain.

Quantum chaos challenges many-body localization. [PDF]
Physical Review E, 2019 Characterizing states of matter through the lens of their ergodic properties is a fascinating new direction of research. In the quantum realm, the many-body localization (MBL) was proposed to be the paradigmatic ergodicity breaking phenomenon, which ...

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.

Classical and quantum chaos in a circular billiard with a straight cut
, 1998 We study classical and quantum dynamics of a particle in a circular billiard with a straight cut. This system can be integrable, nonintegrable with soft chaos, or nonintegrable with hard chaos, as we vary the size of the cut. We use a quantum web to show

Many-Body Level Statistics of Single-Particle Quantum Chaos. [PDF]
Physical Review Letters, 2020 We consider a noninteracting many-fermion system populating levels of a unitary random matrix ensemble (equivalent to the q=2 complex Sachdev-Ye-Kitaev model)-a generic model of single-particle quantum chaos.

Numerical simulation on many-body quantum chaos of ultracold atoms with synthetic gauge fields
Results in Physics, 2022 We investigate the quantum chaos of ultracold atoms in a quadruple-well potential, emphasizing the influence of synthetic gauge fields and many-body atomic interactions on the transitions from regular behavior to quantum chaos.
