High Speed Chaos in Optical Feedback System with Flexible Timescales

, 2003
We describe a new opto-electronic device with time-delayed feedback that uses a Mach-Zehnder interferometer as passive nonlinearity and a semiconductor laser as a current-to-optical-frequency converter.

Transparent, Sprayable Plastic Films for Luminescent Down‐Shifted‐Assisted Plant Growth

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
Spreading the light: A modular approach to down‐shifting europium‐containing polyoxotitanium luminescent cages is developed, allowing their incorporation into sprayable plastic coatings on agricultural greenhouses for accelerated plant growth. Abstract The world's steadily growing population and global heating due to climate change are a threat to food

Chaotic dynamics in a discrete-time predator-prey food chain [PDF]

Computational Ecology and Software, 2015
In this paper, we consider a classical discrete-time food chain model describing predators-prey interaction. The Holling type I functional response is used as the uptake for both predators.

Quantum chaos in non-Markovian open quantum systems: Interferometric OTOC, Loschmidt echo, and commutator operator norm

Chaos: An Interdisciplinary Journal of Nonlinear Science
Out-of-time order correlators (OTOCs) are crucial tools for studying quantum chaos as they show distinct scrambling behavior for chaotic Hamiltonians. We calculate the OTOC and analyze the quantum information scrambling in atom–field and spin–spin interaction models, which are open-system models and exhibit non-Markovian behavior.

Global stability, limit cycles and chaotic behaviors of second order interpolative sigma delta modulators [PDF]

, 2011
It is well known that second order lowpass interpolative sigma delta modulators (SDMs) may suffer from instability and limit cycle problems when the magnitudes of the input signals are at large and at intermediate levels, respectively.

Chaos and hidden chaos in a 4D dynamical system using the fractal-fractional operators

AIMS Mathematics
Although fractional calculus is about three centuries old, it has become the key to understanding many complex real-world phenomena. During the past few decades, many fractional derivatives have appeared. Among these, the fractal-fractional derivatives have shown acceptance in describing some real-world problems.
