Photons can have half-integer values of angular momentum when they are confined to fewer than three dimensions. That is the conclusion of physicists in Ireland, who have revived an experiment first ...

The glass-like plate at the centre of the photograph is the angular filter. A beam of white light is incident from the right at Brewster's angle and is transmitted through the filter. The red beam of ...

Recently, National Science Review published online the research results on three-dimensionally oriented orbital angular momentum of light from Professor Qiwen Zhan's team at the University of Shanghai ...

Light that twists as it travels and materials whose internal order is knotted like a pretzel are starting to collide in the ...

A leaked Philips catalog suggests that the company is working on significantly expanding its outdoor lighting options. The catalog, found by Hueblog.de, shows that the company is adding the Philips ...
