Probing electron behaviour at the tips of nanocones

One of the ways of improving electrons manipulation is though better control over one of their inner characteristics, called spin. This approach is the object of an entire field of study, known as spintronics. Now, Richard ...

SLAC scientists create twisted light

(Phys.org) —Scientists at SLAC have found a new method to create coherent beams of twisted light – light that spirals around a central axis as it travels. It has the potential to generate twisted light in shorter pulses, ...

Novel beams made of twisted atoms

Physicists have, for the first time, now built a theoretical construct of beams made of twisted atoms. These findings by Armen Hayrapetyan and colleagues at Ruprecht-Karls-University Heidelberg in Germany are about to be ...

A breakthrough in plasmonics

EPFL scientists have discovered how optical signal transmission can be controlled, paving the way for the integration of plasmonics with conventional electronic circuits.

Where are the best windows into Europa's interior?

(Phys.org) —The surface of Jupiter's moon Europa exposes material churned up from inside the moon and also material resulting from matter and energy coming from above. If you want to learn about the deep saltwater ocean ...

Lightning strokes can probe the ionosphere

(Phys.org) —Thunderstorms, and the resulting partially ionized plasma of the ionosphere, can distort radio signals traveling to satellites important to communications, navigation or national security

Graphene switches: Team makes it to first base

Ever since graphene was first isolated a few years ago, this quasi-two-dimensional network made up of a single layer of carbon atoms has been considered the magic material. Not only is graphene mechanically highly resilient, ...
