Precision spectroscopy of helium and related atomic systems continues to serve as a cornerstone of experimental and theoretical quantum physics, offering stringent tests of quantum electrodynamics and ...
A team of physicists has shown that pairs of helium atoms, chilled to near absolute zero and launched into each other, can ...
Charged helium nanodroplets stored in an ion trap for a full minute, 10,000x longer than before, open breakthrough possibilities in nanocalorimetry and nanoscale research. The new time span, which is ...
