Topologist Predicts New Form of Matter� - Technology Review: "And topology is about to extend its influence, if Baas has his way. He points out that Borromean rings are just the simplest example of an entire periodic table of topological structures. And if it's possible to make Efimov states that are equivalent to Borromean rings, then it ought to be possible to make the others too.
This family of stuff will be a new state of matter that is governed by news rules, a kind of 'Efimov physics'.
How might this stuff behave? That isn't yet clear but Baas raises an interesting possibility. The deep and unworldly link between particles in Efimov states is remarkably similar to quantum entanglement."
