Phase Diagram of Neutral Quark Matter at Moderate Densities
We discuss the phase diagram of moderately dense, locally neutral three-flavor quark matter using the framework of an effective model of quantum chromodynamics with a local interaction. The phase diagrams in the plane of temperature and quark chemical potential as well as in the plane of temperature and lepton-number chemical potential are discussed.
متن کاملPhase diagram of the anisotropic Kondo chain.
We establish the phase diagram of the one-dimensional anisotropic Kondo lattice model at T = 0 using a generalized two-dimensional classical Coulomb gas description. We analyze the problem by means of a renormalization group treatment. We find that the phase diagram contains regions of paramagnetism, partial and full ferromagnetic order.

متن کاملPhase diagram of neutral quark matter: Self-consistent treatment of quark masses
Theoretical studies suggest that quark matter at suffi ciently high densities and suffi ciently low temperatures may be a color superconductor. (For a review on color superconductivity see for example, Ref. [1].) In nature such conditions appear in the central regions of neutron stars. Therefore it is possible that matter is color superconducting in the cores of these objects. In compact stars ...
متن کاملEffects of density-dependent quark mass on phase diagram of three-flavor quark matter
Considering the density dependence of quark mass, we investigate the phase transition between the ( unpaired ) strange quark matter and the color-flavor-locked matter, which are supposed to be two candidates for the ground state of strongly interacting matter. We find that if the current mass of strange quarkms is small, the strange quark matter remains stable unless the baryon density is very ...
