The superconducting diode effect in a device based on coupled Josephson junctions

The so-called superconducting (SC) diode effect is an interesting nonreciprocal phenomenon, occurring when a material is SC in one direction and resistive in the other. This effect has been the focus of numerous physics studies, ...

Probing fundamental symmetries of nature with the Higgs boson

Where did all the antimatter go? After the Big Bang, matter and antimatter should have been created in equal amounts. Why we live in a universe of matter, with very little antimatter, remains a mystery. The excess of matter ...
