Fractal modes in unstable resonators

Article Abstract:

It has been established that the pecular eigenmodes of unstable resonators are fractals. This finding could enhance understanding of phenomena such as pattern formation. It may also have practical application to lasers using unstable resonators. This research helps explain why a tetraedical stacking of four reflecting spheres represents a chaotically scattering system with inherent fractal properties. Light rays repeatedly scattering in the inner chamber of the tetraedical stacking experience geometrical magnification as a result of the reflecting spheres.

The large-scale smoothness of the Universe

Article Abstract:

Attempts to determine the distribution of matter face the obstacle that most of the mass in the Universe is dark, detected only by its gravitational effect on observable objects. It is also not clear how the distributions of light and mass can be related. The Universe is essentially fractal, although the majority of cosmologists believe it becomes isotropic and homogeneous on larger scales. Data now provides a picture of the gradual move from small-scale fractal behaviour to large-scale homogeneity.

Branched fractal patterns in non-equilibrium electrochemical deposition from oscillatory nucleation and growth

Article Abstract:

The non-equilibrium electrodeposition of metals is responsible for the formation of branched fractal structures, which are seen as model systems for branching and fractal growth process studies. Studies concentrate on large-scale structure, but a new experiment suggests that branched electrodeposits could occur from an oscillatory character in the nucleation kinetics. The given nucleation event is though to be followed by a recovery stage, generating polycrystalline deposits.
