Quark-clustering in cold quark matter

Quarks are proposed to be grouped together to make quark-clusters clue to the strong interaction in cold quark matter at a few nuclear densities, because a weakly coupling treatment of the interaction between quarks there would be inadequate. Cold quark matter is then conjectured to be in solid state (i e, forming crystal structure) if the inter-cluster potential is deep enough to localize clusters in lattice Such a solid state of cold quark matter would be very necessary for us to understand different manifestations of pulsar-like compact stars, and could not be ruled by first principles.Physics, NuclearPhysics, Particles & FieldsSCI(E)CPCI-S(ISTP)
