Particle Physicists Detect ‘Magic’ at the Large Hadron Collider ( www.quantamagazine.org )

Ninety million times a year, when protons crash together at the Large Hadron Collider (LHC), they produce, in their wreckage, a top quark and an anti-top quark, the heaviest known elementary particles. In the trillionth of a trillionth of a second before the particles decay into lighter pieces, they fly apart. But they remain ...

Mirrorless laser: Physicists propose a new light source ( phys.org )

A team of physicists from the University of Innsbruck and Harvard University has proposed a fundamentally new way to generate laser light: a laser without mirrors. Their study, published in Physical Review Letters, shows that quantum emitters spaced at subwavelength distances can constructively synchronize their photon emission ...
