Physical Review C, 1986
In cold quark matter, quantum chromodynamic binding effects can favor clustering of three quarks into nucleon-like clusters. An equation of state of clustered quark matter is derived. It is estimated that the adiabatic transformation of nuclear matter to clustered quark matter sets in at about 1 baryon/fmT, while at the minimum of the energy per baryon

STABILITY OF QUARK MATTER AND QUARK STARS
New Worlds in Astroparticle Physics, 2003We use the confining chromodielectric model to study quark matter. In the version of the model with a quartic potential for the confining field we obtain two solutions for the mean-field equations. The resulting equations of state for strange quark matter are degenerate at large densities with a small energy barrier between them.

QUARK CONFINEMENT AND THE PROPERTIES OF QUARK MATTER
International Journal of Modern Physics E, 2010The properties of two-flavor quark matter are investigated with a model which incorporates the confinement by density-dependent quark masses (CDDM). The results are compared with those in the conventional MIT bag model. It is found that the density behavior of quark matter in the two models are significantly different. Specially, the second derivative

Physical Review Letters, 1988
Studies of the Schwinger-Dyson equation for the gluon propagator in the pure gauge sector have shown it to be strongly enhanced at low momenta. This enhancement in turn generates a severe suppression of the fermion propagator for massless quarks at the same low momenta, killing the pole at p = 0.

Quark-clustering in cold quark matter
Chinese Physics C, 2010Quarks are proposed to be grouped together to make quark-clusters due 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 a crystal structure) if the inter ...

1993
Quantum chromodynamics (QCD) was constructed as a theory of strong interactions, to provide a unique description of the experimental situation in the beginning of the 70’s. However, it was soon realized that one of the properties of QCD, asymptotic freedom1, also has quite striking consequences for the equilibrium thermodynamics of strongly interacting

Properties of strange quark matter
Physical Review D, 1993Assuming that the novel nuclei of [ital A]=370 amu and [ital Z]=14 recently observed in high-energy cosmic rays are really strange quark matter (SQM), the relationship between parameters describing SQM is discussed and the mass formula for SQM is derived by requiring that it yields the observed value of [ital A]=370 amu and [ital Z]=14.

A model for turning quark matter into nuclear matter by clustering of quarks
Progress in Particle and Nuclear Physics, 1985Abstract We investigate the problem of a dynamical clustering mechanism of 3-color quarks into nuclear matter using a short-range quark-quark interaction. Our method is variational with a trial wave function which is an extension of the BCS ground state wave function of the pairing problem to the 3-color tripleting problem.
