Bilayer graphene inspires two-universe cosmological model

Physicists sometimes come up with crazy stories that sound like science fiction. Some turn out to be true, like how the curvature of space and time described by Einstein was eventually borne out by astronomical measurements. ...

Straintronics: Engineers create piezoelectric graphene

In what became known as the 'Scotch tape technique," researchers first extracted graphene with a piece of adhesive in 2004. Graphene is a single layer of carbon atoms arranged in a honeycomb, hexagonal pattern. It looks like ...

Fairy circles found in Australian outback

(Phys.org)—A small team of researchers from Germany, Israel and Australia has confirmed that fairy circles exist in a part of the Australian outback. In their paper published in Proceedings of the National Academy of Sciences, ...

Superconductivity with a twist explained

Leiden physicists and international colleagues from Geneva and Barcelona have confirmed the mechanism that makes magic-angle graphene superconducting. This is a key step in elucidating high-temperature superconductivity, ...

Spheres can form squares

Everybody who has tried to stack oranges in a box knows that a regular packing of spheres in a flat layer naturally leads to a hexagonal pattern, where each sphere is surrounded by six neighbours in a honeycomb-like fashion. ...

Moiré patterns facilitate discovery of novel insulating phases

Materials having excess electrons are typically conductors. However, moiré patterns—interference patterns that typically arise when one object with a repetitive pattern is placed over another with a similar pattern—can ...
