Anomalous quantum transport phenomena observed in fractal photonic lattices

Fractals are complex structures that usually exhibit self-similarity and have a non-integer dimension. The terminology "fractal" was first introduced by the famous mathematician Benoit B. Mandelbrot. He noticed that here ...

What causes earthquake foreshocks?

On the morning of July 4, 2019, a series of very small earthquakes began to rumble in the Mojave Desert, not far from the southern California town of Ridgecrest.

Turbulence in interstellar gas clouds reveals multi-fractal structures

In interstellar dust clouds, turbulence must first dissipate before a star can form through gravity. A German-French research team has now discovered that the kinetic energy of the turbulence comes to rest in a space that ...

A new bridge between the geometry of fractals and the dynamics of partial synchronization

In mathematics, simple equations can generate a complex evolution in time and intriguing patterns in space. One famous example of this is the Mandelbrot set, named after the French-American mathematician of Polish origin, ...

Electromagnetic levitation whips nanomaterials into shape

In order for metal nanomaterials to deliver on their promise to energy and electronics, they need to shape up—literally.

Physicists find a novel way to switch antiferromagnetism on and off

When you save an image to your smartphone, those data are written onto tiny transistors that are electrically switched on or off in a pattern of "bits" to represent and encode that image. Most transistors today are made from ...

'Colloidal gels,' ubiquitous in everyday products, divulge their secrets

Researchers at MIT have developed a new method for determining the structure and behavior of a class of widely used soft materials known as weak colloidal gels, which are found in everything from cosmetics to building materials. ...

Ancient ammonoids' shell designs may have aided buoyancy control

Ammonoids, ancestors of today's octopus, squid and cuttlefish, bobbed and jetted their way through the oceans for around 340 million years beginning long before the age of the dinosaurs. If you look at the fossil shells of ...

Researchers derive urban scaling laws from the 3D geometry of a city

When complex systems double in size, many of their parts do not. Characteristically, some aspects will grow by only about 80 percent, others by about 120 percent. The astonishing uniformity of these two growth rates is known ...
