Some open questions in ‘wave chaos’ [PDF]
Nonlinearity, 2008 The subject area referred to as "wave chaos", "quantum chaos" or "quantum chaology" has been investigated mostly by the theoretical physics community in the last 30 years. The questions it raises have more recently also attracted the attention of mathematicians and mathematical physicists, due to connections with number theory, graph theory, Riemannian,

IEEE Access, 2021 Nature-inspired metaheuristic optimization algorithms, e.g., the butterfly optimization algorithm (BOA), have become increasingly popular. The BOA, which adapts the food foraging and social behaviors of butterflies, involves randomly defined, algorithmic-

Wave chaos in elastodynamic cavity scattering
Europhysics Letters (EPL), 2005 The exact elastodynamic scattering theory is constructed to describe the spectral properties of two- and more-cylindrical cavity systems, and compared to an elastodynamic generalization of the semi-classical Gutzwiller unstable periodic orbits formulas. In contrast to quantum mechanics, complex periodic orbits associated with the surface Rayleigh waves

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 ...

Simulating waves, chaos and synchronization with a microcontroller
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2019 The spatiotemporal dynamics of complex systems have been studied traditionally and visualized numerically using high-end computers. However, due to advances in microcontrollers, it is now possible to run what once were considered large-scale simulations using a very small and inexpensive single integrated circuit that can furthermore send and receive ...

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

Meeting of Chemical Wave Fronts Creates Chaos
MathematicsWe consider systems of reaction–diffusion equations. We describe a new effect in the wave interaction for these systems: the collision of several travelling fronts may induce chaos or periodic oscillations. This effect depends on the initial locations of

Wave Chaos for the Helmholtz Equation [PDF]
, 2010 This chapter is an introduction to the semiclassical approach for the Helmholtz equation in complex systems originating in the field of quantum chaos. A particular emphasis will be made on the applications of trace formulae in paradigmatic wave cavities known as wave billiards.

Featureless Broadband Chaos Through Cascaded Optically Injected Semiconductor Lasers
PhotonicsOptical chaos generated by a semiconductor laser under cascaded optical injection is experimentally and numerically investigated. A semiconductor slave laser under continuous-wave optical injection from a master laser is employed as the chaotic laser ...
