Twisting neutrons: Orbital angular momentum of neutron waves can be controlled

It's easy to contemplate the wave nature of light in common experience. White light passing through a prism spreads out into constituent colors; it diffracts from atmospheric moisture into a rainbow; light passing across ...

Surfing over simulated ripples in graphene

The single-carbon-atom-thick material, graphene, featuring ripples is not easy to understand. Instead of creating such ripples physically, physicists investigating this kind of unusually shaped material rely on a quantum ...

Understanding of complex networks could help unify gravity and quantum mechanics

Mathematicians investigating one of science's great questions—how to unite the physics of the very big with that of the very small—have discovered that when the understanding of complex networks such as the brain or the ...

Âé¶¹ÒùÔºicists create exotic states that could lead to new kinds of sensors and optical devices

The Dirac cone, named after British physicist Paul Dirac, started as a concept in particle and high-energy physics and has recently became important in research in condensed matter physics and material science. It has since ...

Long-sought chiral anomaly detected in crystalline material

A study by Princeton researchers presents evidence for a long-sought phenomenon—first theorized in the 1960s and predicted to be found in crystals in 1983—called the "chiral anomaly" in a metallic compound of sodium and ...

Phagraphene, a relative of graphene, discovered

A group of scientists from Russia, the USA and China have predicted the existence of a new two-dimensional carbon material via computer generated simulation, a "patchwork" analogue of graphene called phagraphene. The results ...

Parity effect observed in graphene

Researchers have theoretically projected and successfully proven through experimentation the parity effect of the quantum Hall edge transport in graphene antidot devices with pn junctions (PNJs). Graphine, or single-layered ...

Scientists propose 3D graphene-like 'hyper-honeycomb' structures

(Âé¶¹ÒùÔº)—Scientists have proposed a new family of structures that are three-dimensional (3D) variations of graphene, the simplest example of which is called a "hyper-honeycomb." If the proposed structures can be experimentally ...

Weyl points: Long-sought phenomenon finally detected

Part of a 1929 prediction by physicist Hermann Weyl—of a kind of massless particle that features a singular point in its energy spectrum called the "Weyl point,"—has finally been confirmed by direct observation for the ...
