Physicists confront the neutron lifetime puzzle

 Quantum Physics News
 28 June 2022
To solve a long-standing puzzle about how long a neutron can "live" outside an atomic nucleus, physicists entertained a wild but testable theory positing the existence of a right-handed version of our left-handed universe. They designed a mind-bending experiment at the Department of Energy's Oak...

Lawrence Livermore National Laboratory (LLNL) scientists recently obtained high-precision thermodynamic data on warm dense nitrogen at extreme conditions that could lead to a better understanding of the interiors of celestial objects like white dwarfs and exoplanets....

New kirigami-inspired models predict how new metamaterials behave

A traditional paper crane is a feat of artistry. Every fold in origami leads to the transformation of a single square sheet of paper into a bird, a dragon, or a flower. Origami discourages gluing, marking or cutting the paper, but in the art of kirigami, strategically placed cuts can transform the...

Getting more information by measuring faster and averaging less

 Physics General News

For signals barely larger than the noise in a system, measurement is generally a trade-off between speed and precision. Averaging over several measurements reduces the influence of noise but takes (a lot of) time. That could change with a revolutionary new measurement method, devised by AMOLF...

Single-atom tractor beams power chemical catalysis

By trapping light into tiny gaps only a few atoms wide, a team from the NanoPhotonics Center at the Cavendish Laboratory at the University of Cambridge has magnified optical forces a thousand-fold, strong enough to force atoms into positions that drive chemical reactions more efficiently....
