Different Facets of Chaos in Quantum Mechanics

, 1999
Nowadays there is no universally accepted definition of quantum chaos. In this paper we review and critically discuss different approaches to the subject, such as Quantum Chaology and the Random Matrix Theory.

Predictability of orbits in coupled systems through finite-time Lyapunov exponents

New Journal of Physics, 2013
The predictability of an orbit is a key issue when a physical model has strong sensitivity to the initial conditions and it is solved numerically.

Semiquantum chaos

Physical Review Letters, 1994
We consider a system in which a classical oscillator is interacting with a purely quantum mechanical oscillator, described by the Lagrangian $ L = \frac{1}{2} \dot{x}^2 + \frac{1}{2} \dot{A}^2 - \frac{1}{2} ( m^2 + e^2 A^2) x^2 \>, $ where $A$ is a classical variable and $x$ is a quantum operator.

Quantum Chaos Versus Classical Chaos: Why is Quantum Chaos Weaker?

, 2006
We discuss the questions: How to compare quantitatively classical chaos with quantum chaos? Which one is stronger?

Evolution of Philosophical Strategies for Interacting with Chaos [PDF]

, 2015
After the discoveries of such scholars as J. H. Poincaré, E. N. Lorenz, I. Prigogine, etc. the term ‘chaos’ is used actively by representatives of various scientific fields; however, one important aspect remains uninvestigated: which attitude one should ...

Chaotic iterations versus Spread-spectrum: chaos and stego security [PDF]

, 2010
A new framework for information hiding security, called chaos-security, has been proposed in a previous study. It is based on the evaluation of unpredictability of the scheme, whereas existing notions of security, as stego-security, are more linked to ...

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

Chaos Theology: A New Creation Theology and Its Applications [PDF]

, 2012
The problems inherent in creatio ex nihilo have led the author to the development of a new creation theology: chaos theology. Its main points are creation from an unexplained initial chaos, a remaining chaos element that is the source of physical and ...

Resurvey of order and chaos in spinning compact binaries

, 2010
This paper is mainly devoted to applying the invariant, fast, Lyapunov indicator to clarify some doubt regarding the apparently conflicting results of chaos in spinning compact binaries at the second-order post-Newtonian approximation of general ...

Stabilization of Miscible Aqueous Phases via Diffusion‐Controlled Multifunctional Nanoparticle‐Ligand Complexation

Advanced Functional Materials, EarlyView.
This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.
