Scientists at NPL recently published findings on laser frequency stabilization, demonstrating an unprecedented level of performance using an optical reference cavity. This advancement features a beyond state-of-the-art optical ...
Researchers from the Institute for Molecular Science (IMS)/SOKENDAI and Kyushu University have uncovered the molecular mechanism that drives the "ticking" of the circadian clock in cyanobacteria.
A research team led by Prof. Chang Hong from the National Time Service Center (NTSC) of the Chinese Academy of Sciences (CAS) has developed a strontium optical lattice clock with both frequency stability and systematic uncertainty ...
In a new study, researchers carried out the most extensive coordinated comparison of optical clocks to date by operating clocks and the links connecting them simultaneously across six countries. Spanning thousands of kilometers, ...
In a new study, physicists at the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions—a feat that many scientists ...
How can the strange properties of quantum particles be exploited to perform extremely accurate measurements? This question is at the heart of the research field of quantum metrology. One example is the atomic clock, which ...
Manuel Endres, professor of physics at Caltech, specializes in finely controlling single atoms using devices known as optical tweezers. He and his colleagues use the tweezers, made of laser light, to manipulate individual ...
One of the most profound open questions in modern physics is: "Is gravity quantum?" The other fundamental forces—electromagnetic, weak, and strong—have all been successfully described, but no complete and consistent quantum ...
You scrambled up a Rubik's cube, and now you want to put it back in order. What sequence of moves should you make?
Laser-cooled atomic gases, gases of atoms chilled to temperatures around absolute zero using laser technologies, have proved to be versatile physical platforms to study and control quantum phenomena. When these atomic gases ...
