Density of states of matter

WebStates of matter In everyday life, there are three states of matter - solids, liquids and gases. The differences between the three states are due to the arrangement and spacing of the particles ... WebWith increasing density, the hadronic bound-state pole smoothly undergoes a crossover toward the Cooper triple phase where the in-medium three-body clusters coexist with the quark Fermi sea. The relation to the quarkyonic matter model can also be found in a natural manner. ... To understand a non-trivial state of matter in the Fermi-degenerate ...
