Tonks-Girardeau gasses are examples of these aggregates, the first of which was created out of approximately 2000 Rubidium-87 atoms near 170 nanoKelvin in June of 1995.  
Feshbach resonances may be observed in these, since a further transition from the collective ground state is required to emit an electron, while Denschlag et al. observed macroscopic solitons in them in 2000.

Resulting from the collapse of bosons into the same ground state at finite temperatures, FTP, name this phase of matter predicted by two physicists, one of whom was German and the other Indian, in the 1920s.
