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 ...

Researchers have successfully created electron-photon pairs in a controlled way in an electron microscope. Researchers from Göttingen (Germany) and Lausanne (Switzerland) have successfully created ...

An international research team has published a comprehensive review in the IEEE Photonics Journal summarising key photonics breakthroughs of 2024, with a spotlight on their pioneering work in coupling ...

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 ...

Illustration of exciton splitting in the organic semiconductor pentacene, which consists of five benzene rings each. Instead of the usual two free charge carriers, absorption of a photon in pentacene ...

Some combinations are more durable than others. In recent years, an interdisciplinary team of Cornell researchers has been pairing microbes with quantum dots, with the goal of creating nano-biohybrid ...

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 ...

Superradiance When multiple electrons emit light in a coordinated manner, the resulting emission is much stronger than the sum of individual emissions. (Courtesy ...

Researchers from Göttingen (Germany) and Lausanne (Switzerland) have successfully created electron-photon pairs in a controlled way in an electron microscope for the first time. Using a new method, ...
