The current template includes under States of matter
Solid, Liquid, Gas, Plasma, Bose–Einstein condensate
Bose gas, Fermionic condensate, Fermi gas, Fermi liquid,
Supersolid Superfluidity Luttinger liquid Time crystal
These are not all of similar character. Some phenomena (Superfluidity) Some are just models (Fermi gas, Luttinger liquid) Some are wanna-bes (Supersolid, Time crystal). If we include these, we could just as well include many more.
For example degenerate matter claims to be a state of matter. I went to the list to show it's not: but then Fermi gas)
How about :
