There are a few kinds of high-energy states too... the most famous ones being electron degenerate matter (found in white dwarfs) and neutron degenerate matter (found in neutron stars). I think a good starting point is here: https://en.wikipedia.org/wiki/State_of_matter https://en.wikipedia.org/wiki/State_of_matter
