For the first time, physicists have used lasers to deep-freeze antimatter. In a new experiment, an ultraviolet laser quelled the thermal jitters of antihydrogen atoms, chilling the antiatoms to just ...

Experiments shed light on pressure-driven ionization in giant planets and stars CREDIT Greg Stewart/SLAC National Accelerator Laboratory Inset by Jan Vorberger/Helmholtz-Zentrum Dresden-Rossendorf ...

A neglected force produced by neutrinos and other particles helps atomic physics measurements align with predictions of the standard model.

Research using the world’s most energetic laser has shed light on the properties of highly compressed matter – essential to understanding the structure of giant planets and stars, and to develop ...
