Atomic clocks are the most precise timekeepers in the world. These exquisite instruments use lasers to measure the vibrations of atoms, which oscillate at a constant frequency, like many microscopic pendulums swinging in ...
JILA physicists have boosted the signal power of their atomic "tweezer clock" and measured its performance in part for the first time, demonstrating high stability close to the best of the latest generation of atomic clocks.
JILA researchers have developed tools to "turn on" quantum gases of ultracold molecules, gaining control of long-distance molecular interactions for potential applications such as encoding data for quantum computing and simulations.
The digital age has seen electronics, including computer chips, shrink in size at an amazing rate, with ever tinier chips powering devices like smartphones, laptops and even autonomous drones. In the wake of this progress, ...
You can't see it. You can't feel it. But the substance scientists refer to as dark matter could account for five times as much "stuff" in the universe as the regular matter that forms everything from trees, trains and the ...
JILA researchers have used a state-of-the-art atomic clock to narrow the search for elusive dark matter, an example of how continual improvements in clocks have value beyond timekeeping.
A team of physicists from the U.S., Poland and Germany proposes to use quantum sensor networks such as atomic clocks of the GPS network or sensors from the Gnome collaboration (a network of shielded atomic magnetometers made ...
Using a new method, physicists at the Heidelberg Max Planck Institute for Nuclear Physics have investigated the ultrafast fragmentation of hydrogen molecules in intense laser fields in detail. They used the rotation of the ...
Optical clocks are so accurate that it would take an estimated 20 billion years—longer than the age of the universe—to lose or gain a second. Now, researchers in the U.S. led by Jun Ye's group at the National Institute of ...
A phenomenon of quantum mechanics known as superposition can impact timekeeping in high-precision clocks, according to a theoretical study from Dartmouth College, Saint Anselm College and Santa Clara University.
