Scientists packed up to 170 strontium atoms inside a single Rydberg atom using a Bose-Einstein Condensate
↗
An international team created a Rydberg polaron by exciting one strontium atom within a Bose-Einstein Condensate, trapping up to 170 other atoms inside its inflated electron orbital.
The experiment demonstrates a controllable way to study quantum interactions at an unusual scale, embedding many atoms within a single atom's electron cloud. Practical applications remain unclear, but the technique offers a platform for probing quantum mechanics and atomic behavior.

A Rydberg atom is created by exciting an electron to a very high energy level, inflating its orbital radius by over 1000 times compared to a normal atom.
Atoms in a Bose-Einstein Condensate are cooled to under a millionth of a degree above absolute zero, minimizing their energy so they can be packed inside the Rydberg orbital without dislodging the excited electron.
Computer simulations indicated up to 170 strontium atoms could fit within the resulting Rydberg polaron.
