Hofstadter's butterfly: Quantum fractal patterns visualized

A team of scientists from Princeton University has measured the energies of electrons in a new class of quantum materials and has found them to follow a fractal pattern. Fractals are self-repeating patterns that occur on ...

From slime molds to corporations, traveling networks chart a new path

You can learn a lot from a little slime mold. For Nate Cira, assistant professor of biomedical engineering in Cornell Engineering, the tiny eukaryotic organism provided inspiration for modeling "traveling networks"—connected ...

Scientists analyze branch patterns in trees and art, from da Vinci to Mondrian

The math that describes the branching pattern of trees in nature also holds for trees depicted in art—and may even underlie our ability to recognize artworks as depictions of trees.

Engineers design new autonomous system to monitor Arctic's melting ice

The rapid melting and thinning of the Arctic ice has sparked serious concerns in the scientific community. In addition, sea ice thickness has also decreased, which makes ice cover more vulnerable to warming air and ocean ...

Is the universe a fractal?

For decades, cosmologists have wondered if the large-scale structure of the universe is a fractal: if it looks the same no matter the scale. And the answer is: no, not really. But in some ways, yes. Look, it's complicated.

Quasiperiodicity changes the ground-state properties of 1D narrow-band moiré systems, study demonstrates

Moiré materials, such as twisted bilayer graphene, are materials generally formed by stacking two or more layers of 2D materials on top of each other with a small lattice mismatch. This slight mismatch creates a unique pattern ...
