Efimov states
"Tractable three-body problems are rare, which is why Vitaly Efimov’s study in 1970 proposing that bound states could exist between three interacting bosons was so intriguing. It took more than3 0 years, though, to observe Efimov states in an ultracold gas of cesium atoms, in which interactions could be controlled with a magnetic field. Now, writing in Physical Review Letters, theorists suggest similar states should also exist between dipolar molecules."
