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...
导读：由上海天文台科学家领衔的ATOMS项目组近期发现了近百个具有丰富化学特征的大质量 “分子热核(hot molecular core)”，并对这些“宇宙化工厂”的演化时标进行了限制。
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...
