Multi-core and series-resonance (SR) techniques have been proposed to achieve ultra-low phase noise (PN) performance. In this article, a scalable ring-coupling scheme is proposed for multi-core ...

What is now called “resonance theory” has a long and conflicted history. We first sketch the early roots of resonance theory, its heritage of diverse physics and chemistry conceptions, and its ...

A new material platform has enabled scientists to create photon pairs whose entanglement can be tuned from a layer thinner than a human hair.
