To get a grip on that, we need to introduce three concepts: the Bose Einstein Condensate, which forms the crowd of very cold atoms; a polaron, which is the mechanism that traps the atoms inside the outer shell of the doll; and finally, Rydberg atoms, a way to make an atom very large and very empty.
