An international research team led by the Paul Scherrer Institute PSI has measured the radius of the nucleus of muonic helium-3 with unprecedented precision. The results are an important stress test ...

A new computational method allows modern atomic models to learn from experimental thermodynamic data, according to a University of Michigan Engineering and Université Paris-Saclay study published in ...

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, ...

Years before Robert Oppenheimer led the Los Alamos lab that developed the first nuclear weapons, physicists in D.C. thrust the world into the atomic age — inside a narrow, zigzagging tunnel running ...

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 ...

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 ...

The University of Wisconsin’s physics department was recognized for its experimentation and creation of one of the most highly-efficient atomic clocks ever. The optical lattice atomic clock is behind ...

The Heising-Simons Foundation recently announced $3 million in multi-institution grants for theoretical and experimental research on Informing Gravity Theory. Half of the award has been granted to a ...

For decades, researchers have toyed with antimatter while searching for new laws of physics. These laws would come in the form of forces or other phenomena that would strongly favor matter over ...
