Physicists find doubly transient chaos can emerge due to dissipation

(Phys.org) —A team of researchers, one from the U.S. and the others from Hungary, has found that a condition they've dubbed doubly transient chaos can emerge from a system due to dissipation. In their paper they've had published ...

Two teams use cold atoms and lasers to create a system that should exhibit Hofstadter's butterfly

(Phys.org) —Two teams working independently of each other have created systems that are expected to exhibit Hofstadter excitations (a butterfly). One team was run by lead researchers at the University of Munich and the Max ...

Spinning atoms in light crystals

(Phys.org) —After more than 40 years of intense research, experimental physicists still seek to explore the rich behaviour of electrons confined to a two-dimensional crystalline structure exposed to large magnetic fields. ...

How fluid dynamics and transport shaped the structure of our lungs in the course of evolution

Two French physicists, Bernard Sapoval and Marcel Filoche from École Polytechnique in Palaiseau, France, suggest in a study published in European Physical Journal E how evolution has shaped our lungs through successive optimisations ...

Wildfires may contribute more to global warming than previously predicted

Wildfires produce a witch's brew of carbon-containing particles, as anyone downwind of a forest fire can attest. A range of fine carbonaceous particles rising high into the air significantly degrade air quality, damaging ...

Building 3-D fractals on a nanoscale: Structure repeats itself from micro to nano

It all starts with a single octahedron structure, then after four iterations there are already 625 of them. Each iteration creates a new octahedron at each vertex. The result is a fascinating 3D fractal construction on micro ...

Fractal patterns spontaneously emerge during bacterial cell growth

Scientists discover highly asymmetric and branched patterns are the result of physical forces and local instabilities; research has important implications for understanding biofilms and multicellular systems.

Building 3-D fractals on a nano scale

It starts with one 3D structure with eight planes, an octahedron. This repeats itself to smaller octahedra: 625 after just four steps. At every corner of a new octahedron, a successive octahedron is formed. A truly fascinating ...
