Completely Mixing Quantum Open Systems and Quantum Fractals [PDF]

, 1999
Departing from classical concepts of ergodic theory, formulated in terms of probability densities, measures describing the chaotic behavior and the loss of information in quantum open systems are proposed.

Nonchaotic Behavior and Transition to Chaos in Lorenz-like Systems Having Invariant Algebraic Surfaces

Chaos Theory and Applications, 2022
The famous and well-studied Lorenz system is considered a paradigm for chaotic behavior in three-dimensional continuous differential systems. After the appearance of such a system in 1963, several Lorenz-like chaotic systems have been proposed and ...

Chaotic Behavior in Exchange Rate

International Journal of Financial Research, 2018
In this paper, we aim to analyze the chaotic structure of the daily Euro/USD parity. The examined data covers the period of 01/01/2004 and 03/04/2018. In this context firstly, to determine chaotic behavior of daily Euro/USD rates, the BDS test was used.

A 2D Chaotic Oscillator for Analog IC

IEEE Open Journal of Circuits and Systems, 2022
In this paper, we have proposed the design of an analog two-dimensional (2D) discrete-time chaotic oscillator. 2D chaotic systems are studied because of their more complex chaotic behavior compared to one-dimensional (1D) chaotic systems.

Optimizing chaotic systems by orbit counting and Fourier spectrum: FPGA implementation and image encryption application

Mathematical Modelling and Analysis
The optimization of chaotic systems has been performed by considering dynamical characteristics of the mathematical models. The proposed work shows the application of genetic algorithms (GAs) to optimize the chaotic behavior of three well-known systems,

Single-photon-triggered quantum chaos [PDF]

, 1952
We demonstrate how to manipulate quantum chaos with a single photon in a hybrid quantum device combining cavity QED and optomechanics. Specifically, we show that this system changes between integrable and chaotic relying on the photon-state of the ...

A Nonlinear Method for Characterizing Discrete Defects in Thick Multilayer Composites

Applied Sciences, 2019
Discrete defects in thick composites are difficult to detect for the small size and the structure noise that appears in multilayer composites. In this paper, a nonlinear method, called recurrence analysis, has been used for characterizing discrete ...
