TL;DR: The Nambu-Jona-Lasinio (NJL) model as mentioned in this paper is a low-energy effective theory of QCD, and it has been applied to the system at finite temperature (T ) and density (ϱ) relevant to the early universe, interior of the neutron stars and the ultrarelativistic heavy ion collisions.

TL;DR: The current status of theoretical studies on the quantum chromodynamics (QCD) phase diagram at finite temperature and baryon chemical potential is reviewed with special emphasis on the origin of various phases and their symmetry breaking patterns as mentioned in this paper.

TL;DR: In this article, the authors describe the structure of neutron stars constructed from the unified equations of states with crossover, and present the current equations of state-called "QHC18" for quark-hadron crossover-in a parametrized form practical for neutron star modeling.

TL;DR: Analyzing correlation functions of charmonia at finite temperature (T) on 32(3)x(32-96) anisotropic lattices by the maximum entropy method (MEM) finds that J/psi and eta(c) survive as distinct resonances in the plasma even up to T approximately 1.6T(c), which suggests that the deconfined plasma is nonperturbative enough to hold heavy-quark bound states.

TL;DR: In this article, the nucleon-nucleon potential is studied by lattice QCD simulations in the quenched approximation, using the plaquette gauge action and the Wilson quark action on a ${32}^{4}$ [$\ensuremath{\simeq}(4.4
