HL-LHC magnet endurance test further confirms niobium–tin’s resilience（图）
HL-大型强子对撞机 耐久性测试 铌锡磁铁 弹性
2023/5/26
Future accelerator projects, including the high-luminosity upgrade of the Large Hadron Collider, will rely on niobium–tin (Nb3Sn) alloys for their superconducting components, such as electromagnets. T...
第31届国际纯粹与应用物理联合会（IUPAP）全体大会暨IUPAP执行委员会和专业委员会主席会议（Executive Council and Commission Chairs, EC&CC）于2022年7月5-14日在意大利的Trieste举办。由于全球疫情影响，会议采取线上线下相结合的方式召开。中国物理学会组织以副理事长赵政国院士为团长的七人代表团线上参加会议，代表团成员包括：IUPAP副主席...
Physicists harness quantum “time reversal” to measure vibrating atoms（图）
量子 时间反转 振动原子 原子钟 量子传感器
2023/6/9
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...
In the Standard Model of particle physics, the Brout–Englert–Higgs mechanism provides mass to elementary particles. While physicists are carrying out direct studies of the Higgs boson to test this mec...
A curious thing happened when MIT researchers Adam Vernon and Ronald Garcia Ruiz, along an international team of scientists, recently performed an experiment in which a sensitive laser spectroscopy te...
At CERN’s Large Hadron Collider (LHC), studies of rare processes allow scientists to infer the presence of heavy particles, including undiscovered particles, that cannot be directly produced. Such par...
Physicists discover a “family” of robust, superconducting graphene structures（图）
超导 石墨烯 结构“家族” 超导器件
2023/6/8
When it comes to graphene, it appears that superconductivity runs in the family.
If you asked the average Pennsylvanian why they were celebrating the 4th of July this year, they would probably tell you that it was to mark Independence Day.
Though they are discrete particles, water molecules flow collectively as liquids, producing streams, waves, whirlpools, and other classic fluid phenomena.
Not so with electricity. While an electric c...
The international LHCb collaboration at the Large Hadron Collider (LHC) has observed three never-before-seen particles: a new kind of “pentaquark” and the first-ever pair of “tetraquarks”, which inclu...
ATLAS and CMS release results of most comprehensive studies yet of Higgs boson’s properties（图）
ATLAS CMS 希格斯玻色子
2023/5/26
Today, exactly ten years after announcing the discovery of the Higgs boson, the international ATLAS and CMS collaborations at the Large Hadron Collider (LHC) report the results of their most comprehen...
世界首个原子级量子集成电路推出
自然 原子级 量子集成电路
2022/10/17
据发表在《自然》杂志上的论文，澳大利亚新南威尔士大学量子计算机物理学家团队设计了一个原子尺度的量子处理器，能够模拟小有机分子的行为，攻克了大约60年前理论物理学家理查德·费曼提出的挑战。该校初创企业“硅量子计算”公司（SQC）6月23日宣布创造出世界上第一个原子级量子集成电路。
Symmetries make the world go round, but so do asymmetries. A case in point is an asymmetry known as charge–parity (CP) asymmetry, which is required to explain why matter vastly outnumbers antimatter i...
CMS on the lookout for new physics（图）
CMS 大型强子对撞机 碰撞事件
2023/5/26
With Run 3 of the LHC just around the corner, the LHC experiments are still publishing new results based on the previous runs’ data. Despite no new discoveries being announced, small deviations from e...
