In an article published in Physical Review Letters on Thursday, scientists carried out an innovative study testing the existence of mirror asymmetries in our universe by studying the handedness of the gravitational-wave emission ...
Researchers at the University of Basel have shown that quantum systems can have antagonistic interactions, too—one agent attracts the other, but the other way around, there is a repulsion. Such interactions could be realized ...
The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second at present. These optical ...
A top-secret lab in the UK is developing the country's first quantum clock to help the British military boost intelligence and reconnaissance operations, the defense ministry said Thursday.
Telling time in space is difficult, but it is absolutely critical for applications ranging from testing relativity to navigating down the road. Atomic clocks, such as those used on the Global Navigation Satellite System network, ...
After its formation, the moon may have been the scene of such immense volcanic activity that its entire crust melted several times and was completely churned through. At that time, the moon orbited significantly closer to ...
In the quest for ultra-precise timekeeping, scientists have turned to nuclear clocks. Unlike optical atomic clocks—which rely on electronic transitions—nuclear clocks utilize the energy transitions in the atom's nucleus, ...
A group of Brazilian researchers has presented an innovative proposal to resolve a decades-old debate among theoretical physicists: How many fundamental constants are needed to describe the observable universe? Here, the ...
For experiments that require ultra-precise measurements and control over atoms—think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates—lasers are the technology of choice, the more spectrally pure ...
Could a decades-long debate about the mysterious movements of stars in Omega Centauri, the largest star cluster in the Milky Way, finally be resolved?
