This progression is known as the intermittency route to chaos. Pomeau and Manneville described three routes to intermittency where a nearly periodic system shows irregularly spaced bursts of chaos. [ 3 ] These (type I, II and III) correspond to the approach to a saddle-node bifurcation , a subcritical Hopf bifurcation , or an inverse period ...
Fluorescence intermittency, or blinking, is the phenomenon of random switching between ON (bright) and OFF (dark) states of the emitter under its continuous excitation. It is a common property of the nanoscale emitters (molecular fluorophores , colloidal quantum dots ) related to the competition between the radiative and non-radiative ...
Blinking colloidal nanocrystals is a phenomenon observed during studies of single colloidal nanocrystals that show that they randomly turn their photoluminescence on and off even under continuous light illumination. [1]
The importance will be revealed by Pomeau himself (and a collaborator, Paul Manneville) through the "scenario" of Intermittency, proposed in 1979. The second path suggested by Pomeau and Ibanez is the idea of realizing dynamical systems even simpler than that of Lorenz, but having similar characteristics, and which would make it possible to ...
Spatiotemporal Intermittency I Figure 4: Many defects are generated and turbulently collide ( a = 1.895, ε = 0.1). Figure 5: Each site transits between a coherent state and chaotic state intermittently ( a = 1.75, ε = 0.6), Phase I.
Giorgio Parisi (born 4 August 1948) is an Italian theoretical physicist, whose research has focused on quantum field theory, statistical mechanics and complex systems.His best known contributions are the QCD evolution equations for parton densities, obtained with Guido Altarelli, known as the Altarelli–Parisi or DGLAP equations, the exact solution of the Sherrington–Kirkpatrick model of ...
The simplest measure is the recurrence rate, which is the density of recurrence points in a recurrence plot: [1] =, = (,). The recurrence rate corresponds with the probability that a specific state will recur.
The Gamma-Re model does not intend to model the physics of the problem but attempts to fit a wide range of experiments and transition methods into its formulation. The transition model calculated an intermittency factor that creates (or extinguishes ) turbulence by slowly introducing turbulent production at the laminar-to-turbulent transition ...
