Unlike electrons, quarks cannot wander freely in ordinary matter. They are confined by the strong force within hadrons such as the protons and neutrons that make up atomic nuclei. However, at very hig...
The top quark is very special. It’s the heaviest known elementary particle and therefore strongly interacts with the Higgs boson. The top quark’s interactions with other particles provide promising le...
Throughout human history, most of our efforts to store information, from knots and oracle bones to bamboo markings and the written word, boil down to two techniques: using characters or shapes to repr...
High-energy collisions at the Large Hadron Collider (LHC) allow researchers to clearly study heavy Standard Model particles, like the Higgs boson, that decay almost immediately at the LHC collision po...
CP asymmetry is the only non-trivial difference between matter and antimatter found so far. Its discovery in neutral kaon decays in 1964 came as a big surprise to the physics community, but today it i...
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...
What does a six-dimensional figure look like? Theoretical physicist Richard Nally can’t show you exactly, but he does have a sculpture – a pink shape the size of a grapefruit – that can help you imagi...
Superconductors – metals in which electricity flows without resistance – hold promise as the defining material of the near future, according to physicist Brad Ramshaw, and are already used in medical ...
Physicists steer chemical reactions by magnetic fields and quantum interference（图）
磁场 量子干涉 化学反应 量子力学 超冷化学
2023/6/9
Physicists in the MIT-Harvard Center for Ultracold Atoms (CUA) have developed a new approach to control the outcome of chemical reactions. This is traditionally done using temperature and chemical cat...

Physicists observe an exotic “multiferroic” state in an atomically thin material（图）
原子薄材料 “多铁性”状态 磁存储设备
2023/6/7
MIT physicists have discovered an exotic “multiferroic” state in a material that is as thin as a single layer of atoms. Their observation is the first to confirm that multiferroic properties can exist...

五夸克态 粒子物理 强子态 强相互作用
2022/5/18
欧洲核子研究中心的LHCb实验近期观测到一个新的五夸克态存在的迹象。中国科学院大学粒子物理LHCb实验团队的傅金林副教授和意大利国家核物理研究院的科学家合作，在这项研究中作出了突出贡献。研究结果2022年2月7日发表在《物理评论快报》(Physical Review Letters) 上，并选为当期编辑推荐文章(Editors’ Suggestion)。
The sound of a sunset（图）
夕阳 超声工具包 声音

What does a sunset sound like? Or ascending shades of red? Now you can listen in via the Sonification Toolkit, a polished, up-and-running prototype from a year-long initiative powered by the combined ...
Like the transistors in a classical computer, superconducting qubits are the building blocks of a quantum computer. While engineers have been able to shrink transistors to nanometer scales, however, s...
