The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of ato...
ASACUSA sees surprising behaviour of hybrid matter–antimatter atoms in superfluid helium（图）
ASACUSA 超流体氦 物质-反物质原子 混合
2023/5/26
A hybrid matter--–antimatter helium atom containing an antiproton, the proton’s antimatter equivalent, in place of an electron has an unexpected response to laser light when immersed in superfluid hel...
MIT physicists have discovered a new quantum bit, or “qubit,” in the form of vibrating pairs of atoms known as fermions. They found that when pairs of fermions are chilled and trapped in an optical la...
In 2018, Cornell researchers built a high-powered detector that, in combination with an algorithm-driven process called ptychography, set a world record by tripling the resolution of a state-of-the-ar...
