Kolmogorov turbulence, Anderson localization and KAM integrability

open access: yes, 2012
The conditions for emergence of Kolmogorov turbulence, and related weak wave turbulence, in finite size systems are analyzed by analytical methods and numerical simulations of simple models.

Universality and beyond in Optical Microcavity Billiards with Source-Induced Dynamics

open access: yesEntropy, 2023
Optical microcavity billiards are a paradigm of a mesoscopic model system for quantum chaos. We demonstrate the action and origin of ray-wave correspondence in real and phase space using far-field emission characteristics and Husimi functions.

Chaotic synchronization of coupled electron-wave systems with backward waves

open access: yes, 2005
The chaotic synchronization of two electron-wave media with interacting backward waves and cubic phase nonlinearity is investigated in the paper. To detect the chaotic synchronization regime we use a new approach, the so-called time scale synchronization

Enhanced tracer transport by the spiral defect chaos state of a convecting fluid [PDF]

open access: yes, 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

Manifestations of chaos in relativistic quantum systems - A study based on out-of-time-order correlator

open access: yesPhysics Open, 2019
Previous work in the field of relativistic quantum chaos has revealed initial evidence that the manifestations of classical chaos in relativistic quantum systems tend to be weakened as compared with those in nonrelativistic quantum systems. To place this

Controlling transition probability from matter-wave soliton to chaos

open access: yes, 2008
For a Bose-Einstein condensate loaded into a weak traveling optical superlattice it is demonstrated that under a stochastic initial set and in a given parameter region the solitonic chaos appears with a certain probability.

Spatiotemporal Chaos in the Nonlinear Three Wave Interaction [PDF]

open access: yesPhysical Review Letters, 1992
Summary: We examine the spatiotemporal dynamics of the nonlinear three-wave interaction describing the saturation of an unstable wave by coupling to two damped waves. We observe spatiotemporal chaos involving coherent structures that are characterized by temporal and spatial scales determined by the parameters in the problem.

On the existence of chaotic circumferential waves in spinning disks

open access: yes, 2007
We use a third-order perturbation theory and Melnikov's method to prove the existence of chaos in spinning circular disks subject to a lateral point load.

Dynamical Properties of Ion-Acoustic Waves in Space Plasma and Its Application to Image Encryption

open access: yesIEEE Access, 2021
The nonlinear ion-acoustic waves (IAWs) in a space plasma are capable of exhibiting chaotic dynamics which can be applied to cryptography. Dynamical properties of IAWs are examined using the direct method in plasmas composed of positive and negative ions

Nonlinear wave chaos: statistics of second harmonic fields [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2017
Concepts from the field of wave chaos have been shown to successfully predict the statistical properties of linear electromagnetic fields in electrically large enclosures. The Random Coupling Model (RCM) describes these properties by incorporating both universal features described by Random Matrix Theory and the system-specific features of particular ...
