Photons observed moving along the edges of crystal structures (IMAGE)
Caption
Photons, whose measured energies are represented as red streaks in these computer images, were observed moving in a single direction on the three-dimensional edges of special crystal structures that scientists led by Nanyang Technological University, Singapore had designed. The findings suggest that these crystals could be optimised to detect dark matter particles called axions in the future.
