Quantum chaos in topologically massive gravity
Journal of High Energy Physics, 2020 We study quantum chaos of rotating BTZ black holes in Topologically Massive gravity (TMG). We discuss the relationship between chaos parameters including Lyapunov exponents and butterfly velocities from shock wave calculations of out-of-time-order ...

Wave chaos as signature for depletion of a Bose-Einstein condensate [PDF]
, 2012 We study the expansion of repulsively interacting Bose-Einstein condensates (BECs) in shallow one-dimensional potentials. We show for these systems that the onset of wave chaos in the Gross-Pitaevskii equation (GPE), i.e.

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.

Physical Review Letters, 1996 Spatiotemporal chaos in a two-variable, cubic autocatalator model with equal diffusivities of thespecies is described. The interplay between an unstable homogeneous state and propagating frontswhich return the system to that state gives rise to a reinjection mechanism for chaotic behavior. Extremesensitivity to initial conditions in both space and time

Universal spectral correlations in the chaotic wave function and the development of quantum chaos [PDF]
Physical review B, 2017 We investigate the appearance of quantum chaos in a single many-body wave function by analyzing the statistical properties of the eigenvalues of its reduced density matrix $\rho_A$ of a spatial subsystem A.

Subwavelength position sensing using nonlinear feedback and wave chaos. [PDF]
Physical Review Letters, 2011 We demonstrate a position-sensing technique that relies on the inherent sensitivity of chaos, where we illuminate a subwavelength object with a complex structured radio-frequency field generated using wave chaos and nonlinear feedback.

Remote Sensing, 2021 Atmospheric-chemical coupled models usually parameterize sea-salt aerosol (SSA) emissions using whitecap fraction estimated considering only wind speed and ignoring sea state. This approach may introduce inaccuracies in SSA simulation. This study aims to
