The Pauli exclusion principle is a cornerstone of the Standard Model of particle physics and is essential for the structure ...

The results are an important stress test for theories and future experiments in atomic physics. 1.97007 femtometre (quadrillionths of a metre): That’s how unimaginably tiny the radius of the atomic ...

If an atomic physicist like Nathan Lundblad could slip the surly bonds of Earth’s gravitational pull, what kind of experiment would he dream up? About a decade ago, that very question was posed to ...

The Einstein–de Haas effect, which links the spin of electrons to macroscopic rotation, has now been demonstrated in a ...

In March 2018, researchers launched what looks like a white, cooler-sized fridge to the International Space Station. That heavy box houses a $100 million facility known as the Cold Atom Laboratory, ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat. Now a series of experiments at atomic and electronic scales is revealing ...

While many Earth-based experiments have been run to try to detect dark matter, the mysterious substance remains elusive. Now physicists have proposed a new experiment that would try to find signals by ...

New scientific results confirm an anomaly seen in previous experiments, which may point to an as-yet-unconfirmed new elementary particle, the sterile neutrino, or indicate the need for a new ...

EUROPE — Every clock in your house probably tells a slightly different time. Now picture those clocks as the most precise instruments humanity has ever built, so accurate that they wouldn’t lose or ...
