Figure 1: Contactless interactions between photons stored as collective Rydberg excitations in spatially separated channels. Each photonic channel consists of a tightly focused signal beam and a ...

Researchers have discovered that molecules experience non-reciprocal interactions without external forces. Fundamental forces such as gravity and electromagnetism are reciprocal, where two objects are ...

In the race to uncover the deepest secrets of the universe, researchers are turning to powerful new tools. One of the most promising tools is the quantum computer. It offers a way to explore problems ...

“Negative time” might sound like science fiction, but an international team of theorists and experimentalists has determined that a photon can, in fact, spend a negative amount of time in an excited ...

Secondary particle tracks recorded during a proton collision inside the ATLAS detector, indicating the presence of a single Higgs boson in the event. Since the launch of the Large Hadron Collider, ...

In this post, I am going to talk about real and not-real forces, like the fake centrifugal force. (If you don't like the word fake you could replace that with fictitious.) First, an example: Suppose ...
