Dynamics of an acoustically trapped sphere in beating sound waves
Physical Review Research, 2021 A focused acoustic standing wave creates a Hookean potential well for a small sphere and can levitate it stably against gravity. Exposing the trapped sphere to a second transverse traveling sound wave imposes an additional acoustic force that drives the ...

Encryption Device Based on Wave-Chaos for Enhanced Physical Security of Wireless Wave Transmission
IEEE Access, 2023 We introduce an encryption device based on a compact wave-chaotic cavity to enhance the physical security of wireless communication. The proposed encryption device is composed of a compact quasi-2D disordered cavity, where transmit signals pass through ...

Encoding Cumulation to Learn Perturbative Nonlinear Oscillatory Dynamics
Advanced Science, EarlyView.Weak nonlinearities critically shape the long term behavior of oscillatory systems but are difficult to identify from data. A data‐driven framework is introduced to infer governing equations of weakly nonlinear oscillators from sparse and noisy observations.

Physics 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

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

, 2012 The proplem of sound propagation in an oceanic waveguide is considered. Scattering on random inhomogeneity of the waveguide leads to wave chaos. Chaos reveals itself in spectral properties of the finite-range evolution operator (FREO).

Spatiotemporal Chaos in the Nonlinear Three Wave Interaction [PDF]
Physical 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.

Advanced Electronic Materials, EarlyView.Physical reservoir computing (PRC) based on spin wave interference has demonstrated high computational performance, yet room for improvement remains. In this study, we fabricated this concept PRC with eight detectors and evaluated the impact of the number of detectors using a chaotic time series prediction task.

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

Chaos and Einstein-Rosen gravitational waves
Physical Review D, 2023 We demonstrate the existence of chaotic geodesics for the Einstein-Rosen standing gravitational waves. The complex dynamics of massive test particles are governed by a chaotic heteroclinic network. We present the fractal associated with the system under investigation.
