Over the past decade, researchers have become good at creating devices that emit single ...

Quantum technologies, devices and systems that operate leveraging quantum mechanical effects, could tackle some tasks more ...

Dirac electrons were predicted by P. Dirac and discovered by A. Geim, both of whom were awarded the Nobel Prize in Physics in 1933 and in 2010, respectively. Dirac electrons behave like photons rather ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...

An international team of researchers has forced light to replicate the quantum Hall effect, a Nobel Prize–winning phenomenon ...

LEMONT, Ill.--(BUSINESS WIRE)--A new set of electron beam measurements puts the upgraded Advanced Photon Source (APS) at the top of the list of the world’s synchrotron X-ray research facilities. The ...

Controlled generation of single-photon emitters in silicon (red) by broad-beam implantation of ions (blue) through a lithographically defined mask (left) and by a scanned focused ion beam (right).

A better understanding of how electrons convert energy into photons could lead to designing more efficient solar cells or better phototherapies for cancer. Researchers looking into the process have ...

The photoelectric effect is a phenomenon where light knocks electrons out of a material, resulting in the emission of these electrons, called photoelectrons. Albert Einstein explained the ...
