Efimov states and three-body universality
Three atoms that barely interact in pairs can still bind into an infinite ladder of larger and larger molecules, each about 22.7 times bigger than the last for identical atoms. Experiments found that where the ladder starts is set by a simple atomic length, and why is only partly understood.
Why it matters
Efimov physics links atoms, nuclei and halo systems through the same few-body laws, and it controls losses in every resonant quantum gas.
