“…For values of µ which are finite as N c → ∞, T c is independent of µ. Once a Fermi sea of quarks condenses, for µ greater than some mass threshold, at T < T c there is a novel phase, termed "quarkyonic" [2]: while the free energy is, up to the power like corrections, that of free quarks, excitations near the Fermi surface are those of confined states, which are baryons.…”

“…As illustrated in Fig. (1), consider the hadronic phase, which exists in a "box" where T < T c and for values of µ below the mass threshold [2]. Baryons are composed of N c quarks, and so have a mass ∼ N c .…”

“…When baryons condense, there is no way to tell if they (or anything else) are confined or not. This phase is therefore analogous to the quarkyonic phase of large N c and small N f [2]. We also explore the way the phase transition evolves at large N c , as we allow N f from a small value, ≪ N c , to one ∼ N c .…”

We consider the possible phases of a non-Abelian gauge theory, as a function of temperature and quark chemical potential, when both the number of colors and flavors is very large. Generally, a large number of flavors washes out deconfining phase transitions. We show, however, that the degeneracy of even the lightest baryons is exponentially large. This implies that the baryon number (or fluctuations thereof, at zero chemical potential) is an order parameter in the limit of an infinite number of colors and flavors.

“…[25], an interpolation between HM and QM does not provide the microscopic dynamics for the crossover domain, and it was suggested that the crossover can be bridged by the quarkyonic matter. In 2007, McLerran and Pisarski proposed the possible existence of quarkyonic phase in the large N c limit [26], which was suggested to be comprised of "a quark Fermi sea" and "a baryonic Fermi surface". When the density is large enough, a quark does not know which baryon it belongs to and can be viewed as a quasi-free particle [27].…”

We extend the relativistic mean field (RMF) model for hadronic matter to include quark degrees of freedom. In the quarkyonic phase, quarks are treated as quasi-free particles with density dependent masses, where both confinement and leading-order perturbative interactions are included. The effects of Pauli blocking and interactions between quarks and baryons are treated with phenomenenlogical approaches. Nuclear matter, quarkyonic matter and transitions between them are investigated with the extended RMF model. Two types of phase transitions are obtained, one is of first-order and the other of third-order. With the model parameters determined according to the observational masses of pulsars, it is found that the quarkyonic transition is likely to be third-order.

The basic phenomenology of heavy‐ion physics at high energies is reviewed. We discuss the phase diagram of strongly interacting matter, the properties of the different phases, and the dynamical evolution of a heavy‐ion collision. Several observables have been suggested as a signature for a new state of matter, the quark–gluon plasma. These include strangeness enhancement, jet quenching, and suppression. The main results of these measurements are summarized. In addition, global aspects of heavy‐ion collisions, such as centrality determination, particle production, and collective flow are addressed. The current experimental results suggest that indeed a new state of matter is formed in heavy‐ion collisions, which has the properties of an ideal liquid. Finally, an outlook on the future developments in this field is given.
