How to put 170 atoms in an atom

> So in 2018, an international team of scientists created a BEC out of strontium atoms, and hit one of those atoms with a carefully tuned laser, exciting its outermost electron and turning it into a Rydberg atom. Several other atoms from the BEC were caught within between that outer electron’s inflated orbital.

This is not so much putting 170 atoms in one, but inflating one beyond the size of its 170-atom neighbourhood.

The hard part being to cool the neighbourhood to such an extremely low temperature that the inflated atom doesn't ionize.

The article, rather shallow, is about Bose-Einstein Condensate (BEC).

I found it a bit more interesting that the author's middle name is Galileo, and that he is participating in a "blogging" residency [0]:

Wait - if the 170 atoms are a Bose-Einstein Condensate, then they are really just one atom. That's the whole deal with Condensates.

Does this type of atomic engineering have the potential for creating new types of materials, like polymers?

Great way of saving space at home :)

as a naive , it is non-intuitive for me how the lower bound is 0 kelvin, is this the temp where things truly stops oscillating (quantum level) or we just dont care .

I am here to just appreciate the article how clear it is .

The article is well-written, and is very clear, thank you!

Are we getting closer to sophons?

Poor atoms. They froze them to absolute zero, of course they're going to huddle together!

As someone who did blue sky chemistry research decades ago: is this completely pointless?
