Atoms confined to a single line can bind into clusters called Bethe strings. A new experiment points to a mix of many such ...

For the first time, physicists have entangled two atoms while they were in motion and used the result to run one of quantum mechanics’ most rigorous tests on massive, traveling particles. The ...

Atoms are normally made of a nucleus and electrons. But scientists are proposing a hunt for a new variety of atom without either. Tauonium (sometimes called “ditauonium” or “true tauonium”) would ...

Physicists found indirect evidence of Bethe strings, clusters of ultracold cesium atoms predicted by theory, in a ...

Covalent bonds, in which two atoms are bound together by sharing a pair of electrons, form the scaffolding that underpins the majority of organic compounds. In 1931, the Nobel Laureate Linus Pauling ...

A new quantum sensing approach could dramatically improve how scientists measure low-frequency electric fields, a task that has long been limited by bulky setups and blurry resolution. Instead of ...
