A Faraday isolator is an electromagnetic non-reciprocal device, a key element in photonics. It is required to shield electromagnetic sources against the effect of back-reflected light, as well as ...

Optomechanically induced non-reciprocal transparency (OMIT) and amplification (OMIA) are observed, and a non-reciprocal phase shift of up to 40 degrees is demonstrated in this study.

“Non-reciprocal means that one particle pushes the other but the other one doesn’t push back,” explains team member Benjamin Stickler of the University of Duisburg-Essen. “While this behaviour ...

But these non-reciprocal interactions can also occur not just between people, but in the natural world. In a paper published April 14 in the journal Nature , a team of University of Chicago scientists ...

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