To most people, “symmetry” means the bilateral symmetry exhibited by, say, a butterfly, or the human face. That is, if you take a picture of a butterfly and draw a straight line down the middle of the ...

Using holography, researchers have found when gravity is combined with quantum mechanics, symmetry is not possible. A new study by a pair of researchers in the US and Japan has found that, when ...

Redefining the repeating pattern in photonic crystals creates tightly confined pathways for light while preserving symmetry, offering a simple route to ultracompact and low loss light circuits.
