> 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 outer orbital is being treated as the last layer of an onion and the atoms are "inside" that. But orbitals are not spherical so our geometrical intuitions kinda fail.
Hey! That's me, yep. It's a combination of a BEC and a Rydberg atom called "Rydberg polaron". This isn't the scientifically deepest article I've written, but if you want to read a more detailed description, feel free to check out the sources at the bottom.
Since the end of the 30 day residency in November, I and a few other participants have been posting weekly, so I've got a decent back catalogue and there will be more to come!
Not only Bose-Einstein condensate, which is a textbook topic in condensed-matter physics, but also Rydberg atoms, which are a very weird phenomenon that has been mostly studied recently as a sort of edge-case where quantum physics starts to look like classical physics.
One of my sci-fi future ideas, every time I hear about someone thinking of a new way to make warp drives, is that if we ever sort it out someone will make TARDISes for the filthy rich - a static warp bubble that moves space into a ground floor closet or room from space in an upstairs or in the attic.
Like a milder version of the gimmick in Ultraviolet.
From a position of naivety, anything relating to electron dissociation sounds potentially useful for nano-components to use for computation, or for superconductivity?
Honestly, no. These weird states of matter have extremely different properties to ordinary matter. Weird properties is how we get things like superconductors, magnets, semiconductors, photovoltaics.. so strange state of matter with weird properties could very well produce some magic

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]:
Inkhaven residency: A 30 day residency for you to grow as a writer. For one month, you'll publish a blogpost every day. Or pack your bags.
