Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world ...

Researchers at the University of Basel and the Laboratoire Kastler Brossel have demonstrated how quantum mechanical ...

As well as being useful for creating an optical ion clock, this multi-ion capability could also be exploited to create quantum-computing architectures based on multiple trapped ions. And because the ...

A new chart for highly charged ions (HCIs) has been proposed, aiming to replicate the conventional periodic table’s ...

Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up ...

The Einstein-de Haas effect has been observed in a quantum fluid, showing that changes in magnetization transfer angular ...

The time is nigh for nuclear clocks. In a first, scientists have used a tabletop laser to bump an atomic nucleus into a higher energy state. It’s a feat that sets scientists on a path toward creating ...

A long-standing law of thermodynamics turns out to have a loophole at the smallest scales. Researchers have shown that quantum engines made of correlated particles can exceed the traditional ...

Delve into the detail of atomic physics. As the basic units of matter, atoms are the building blocks for everything in the universe. Once thought to be indivisible, we now know they can indeed be ...

The Department of Physics and Astronomy (DPA) has about 330 undergraduate (B.S.) and 310 graduate (Ph.D. and M.S.) alumni. In the U.S., doctoral alumni are employed as faculty, research scientists and ...
