Physicists detect exotic looped trajectories of light in three-slit experiment
6 Jan 17
Physicists have performed a variation of the famous 200-year-old double-slit experiment that, for the first time, involves “exotic looped trajectories” of photons. These photons travel forward through one slit, then loop around and travel back through another slit, and then sometimes loop around again and travel forward through a third

A twist on Hanbury Brown—Twiss interferometry offers new approach for remote sensing
8 Apr 16
In a paper, published in Science Advances today, the researchers demonstrate that for light from a source such as the Sun, random fluctuations of intensity give rise to correlations of twisted light beams. They showed the presence of these correlations by modifying a now classical experiment called Hanbury Brown – Twiss
