Nikuni et al. created a version of these using a group of magnons in an antiferromagnet. Sweeping a magnetic field through them creates a condition in which their particles' degree of freedom couples with their reaction coordinate, creating a Feschbach resonance. Tonks and Girardeau lend their name to a two-dimensional version of this substance, whose wavefunctions are given by the Gross-Pitaevskii equation. The first one was created by Cornell and Weimann by supercooling a group of rubidium atoms, causing them to collapse into a single quantum state. FTP, name this state of matter named for two scientists, in which a group of bosons gel together.
