Chaos and gravitational waves [PDF]
Physical Review D, 2001 The gravitational waveforms of a chaotic system will exhibit sensitive dependence on initial conditions. The waveforms of nearby orbits decohere on a timescale fixed by the largest Lyapunov exponent of the orbit. The loss of coherence has important observational consequences for systems where the Lyapunov timescale is short compared to the chirp ...

East Asian Policy, 2023 The fifth wave of COVID-19 in Hong Kong (2022) had brought a series of chaos to society. Nevertheless, its Asian neighbours, namely Singapore and Macao, have avoided such chaos. By investigating the well-rounded preventive measures and social environment

Enhanced tracer transport by the spiral defect chaos state of a convecting fluid [PDF]
, 2004 To understand how spatiotemporal chaos may modify material transport, we use direct numerical simulations of the three-dimensional Boussinesq equations and of an advection-diffusion equation to study the transport of a passive tracer by the spiral defect

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

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 ...

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.

Direct observation of a "devil's staircase'' in wave-particle interaction [PDF]
, 2006 We report the experimental observation of a "devil's staircase'' in a time dependent system considered as a paradigm for the transition to large scale chaos in the universality class of hamiltonian systems. A test electron beam is used to observe its non-
