Researchers, in a recent Physical Review Letters paper, introduce a new mechanism that may finally allow ultralight dark ...

However, understanding a photon’s geometry, shape, and interactions with matter is crucial to gaining deeper insights into the science that governs the quantum world. For instance, a photon’s ...

"Our experiments investigate the most fundamental interaction between matter and light," commented Victor Leong, a PhD student involved with the research. A four-metre long photon takes about 13 ...

A theorized massive particle called a "dark photon" could help shine a light ... This is because dark matter doesn’t interact with light like the everyday matter that makes up stars, planets ...

A photon is a particle of light ... By understanding this, we set the foundations to be able to engineer light-matter interactions for future applications, such as better sensors, improved ...

If the interaction binding photons and electrons into polaritons ... the realization that the setup could be used to induce matter-mediated photon-photon coupling came as an “aha moment” in the ...

This means that their resulting interaction with matter (i.e. groupings of atoms ... If one were to think of this pulse as discrete quanta of photon particles, it’d seem to break causality ...

With this very strong photon–photon interaction, the two photons form the two-photon ... “It is an almost ideal interface between light and matter at the quantum scale and could be used to generate a ...

However, the bigger surprise came when they realized that it could also allow photons to interact with each other (photon coupling) through matter. “The realization that the setup could be used ...
