Physicists observe behavior of quantum materials in curved space

Light and matter are typically viewed as distinct entities that follow their own, unique rules. Matter has mass and typically exhibits interactions with other matter, while light is massless and does not interact with itself. ...

How does light travel?

Ever since Democritus – a Greek philosopher who lived between the 5th and 4th century's BCE – argued that all of existence was made up of tiny indivisible atoms, scientists have been speculating as to the true nature ...

What are the parts of an atom?

Since the beginning of time, human beings have sought to understand what the universe and everything within it is made up of. And while ancient magi and philosophers conceived of a world composed of four or five elements ...

Short wavelength plasmons observed in nanotubes

The term "plasmons" might sound like something from the soon-to-be-released new Star Wars movie, but the effects of plasmons have been known about for centuries. Plasmons are collective oscillations of conduction electrons ...

Huge reduction of heat conduction observed in flat silicon channels

Combining state-of-the-art realistic atomistic modelling and experiments, a new paper describes how thermal conductivity of an ultrathin silicon membrane is controlled to a large extent by the structure and the chemical composition ...

Quantization of 'surface Dirac states' could lead to exotic applications

Researchers from the RIKEN Center for Emergent Matter Science in Japan have uncovered the first evidence of an unusual quantum phenomenon—the integer quantum Hall effect—in a new type of film, called a 3D topological ...
