Researchers from the University of East Anglia, working with collaborators in South Africa, showed that specially prepared light beams can spontaneously acquire spinning, chiral patterns as they travel through empty space. This effect normally requires lenses, mirrors or engineered materials, but the team produced it using only the light's own internal geometric structure.
Physicists led by Arun Paramekanti at the University of Toronto devised a technique using rotating light to detect atomic vibrations tied to electron spin, revealing a hidden magnetic state called octupolar order that behaves as if it has eight poles instead of the usual two. The findings, published in Physical Review Letters, provide the first direct optical evidence of this exotic quantum magnetic state in crystalline materials.
Researchers at Singapore's Centre for Quantum Technologies, led by Murray Barrett, report building a lutetium-based atomic clock that outperforms previous record-holding clocks made with ytterbium, strontium and aluminum. The findings were published in Nature on September 23. The clock works by locking a laser to lutetium's atomic transition frequency, which then serves as an ultra-precise timekeeping reference.
A commentary argues that government contracts, grants and procurement rules for frontier technologies—space, AI and quantum computing—are quietly locking in dominant suppliers rather than fostering open competition. The authors point to the space sector, where repeated launch contracts to the same firms like SpaceX build data and performance advantages that make it harder for rivals to break in, and warn similar patterns are emerging in AI and quantum funding decisions.
