The Pauli exclusion principle is a cornerstone of the Standard Model of particle physics and is essential for the structure and stability of matter. Now an international collaboration of physicists ...

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 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 ...

Physicists in Germany have carried out the most accurate measurement to date of the width of the proton. By examining a previously unexplored energy-level transition in the hydrogen atom, Lothar ...

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 ...

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, ...

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 ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to Albert Einstein’s instincts about reality. By stripping classic thought ...

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 ...

Dr. Alessio Porcelli, Dr. Catalina Oana Curceanu and Dr. Alberto Clozza, in front of the VIP-2 experimental setup at the Gran Sasso LNGS underground laboratory. The Pauli exclusion principle is a ...
