Chaotic Systems  

In General, Theoretical Models > s.a. chaos / Jerk; network; phase transitions.
* Remark: Almost all conservative dynamical systems are at least partly chaotic.
* Discrete models: For example, the baker map, the Farey map and the Hénon map.
* Continuous models: Particle motion (Billiard – chaotic with convex boundary; Motion in a potential – chaotic if the Gaussian curvature of the potential surface is negative); Gas (Hard spheres – see Sinai's theorem); Simple example

d3x/dt3 = –(dx/dt)3 + (d2x/dt2) (x + d2x/dt2) / (dx/dt) .

Computer Models and Calculations > s.a. computational physics; quantum computation.
* History: 1963, First model introduced by E Lorenz for weather prediction.
* Ubiquity: Chaos is (theoretically) exhibited not only by systems with many degrees of freedom or quantum systems, but also by macroscopic ones with few degrees of freedom, such as hydrodynamic flows near turbulence, mechanical oscillators, plasmas, etc.
@ Chaos and numerical methods: Corless et al PLA(91); Sprott AJP(08)apr [simple models].
@ Chaos introduced by approximations: Ge & Leng PLA(94).

Real Systems > s.a. Billiard; brownian motion; fractals; matter; oscillator; quantum chaos; types of measurement.
* Ubiquity: Found in the onset of fluid turbulence, chemical reactions, electrochemical and other special systems; For less well-controlled systems (full turbulent flow, biological systems, climate, ...) one can only infer chaotic behavior, although quantitative studies have been attempted; We believe chaos to be a universal feature.
* Specific examples: Dendritic growth, group decisions (& Meyer & Brown), snowflakes.
