Lens trick doubles odds for quantum interaction

It’s not easy to bounce a single particle of light off a single atom that is less than a billionth of a metre wide. However, researchers at the Centre for Quantum Technologies at the National University of Singapore have shown they can double the odds of success, an innovation that might be useful in quantum computing and metrology. The findings were published 31 October in Nature Communications.

Physicists discover 'smoke rings' made of laser light

Most basic physics textbooks describe laser light in fairly simple terms: a beam travels directly from one point to another and, unless it strikes a mirror or other reflective surface, will continue traveling along an arrow-straight path, gradually expanding in size due to the wave nature of light. But these basic rules go out the window with high-intensity laser light.

Best of Last Week – Pondering future of inflation theory, an enclosed tube maglev and arguing about contacting aliens

(Phys.org) -Last week was a big one for space science, as it was announced that astronomers created the first realistic virtual universe-a computer simulation called “Illustris” that is able to recreate 13 billion years of cosmic evolution in a cube, with 350 million light-years represented on a side. Scientists hope to use it like a time machine.
