Weyl points, first predicted in 1929, observed for the first time

Part of a 1929 prediction by physicist Hermann Weyl — of a kind of massless particle that features a singular point in its energy spectrum called the “Weyl point” — has finally been confirmed by direct observation for the first time, says an international team of physicists. The finding could lead to new kinds of high-power single-mode lasers and other optical devices, the team says. —> Read More
