On systems of maximal quantum chaos

open access: yesJournal of High Energy Physics, 2021
A remarkable feature of chaos in many-body quantum systems is the existence of a bound on the quantum Lyapunov exponent. An important question is to understand what is special about maximally chaotic systems which saturate this bound.

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

open access: yesChaos 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 ...

A novel synchronization between two different chaotic systems (Convert Lorenz chaotic system to Chua chaotic system)

open access: yesOptical and Quantum Electronics, 2022
Abstract In this work, a new synchronization was achieved between two different chaotic systems in behavior (Chua-Lorenz) by coupling them together with a coupling factor (k) and it was noted that Lorenz's behavior completely transformed Chua's behavior by changing the value of this factor.

Combination Synchronization of Three Different Fractional-Order Delayed Chaotic Systems

open access: yesComplexity, 2019
Time delay is a frequently encountered phenomenon in some practical engineering systems and introducing time delay into a system can enrich its dynamic characteristics. There has been a plenty of interesting results on fractional-order chaotic systems or

Controlling a chaotic system

open access: yesPhysical Review Letters, 1991
Using both experimental and theoretical results, this Letter describes how low-energy, feedback control signals can be successfully utilized to suppress (laminarize) chaotic flow in a thermal convection loop.

Singularity, Observability and Statistical Independence in the Context of Chaotic Systems

open access: yesMathematics, 2023
Pseudorandom number generators (PRNGs) have always been a central research topic in data science, and chaotic dynamical systems are one of the means to obtain scientifically proven data.
