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 ...

Photoionization, the process by which an incident photon ejects an electron from an atom, lies at the heart of many atomic physics studies. Coupled with cross section measurements – which quantify the ...

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 ...

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 ...

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 ...
