Continuum-extrapolated lattice QCD simulations with complex Langevin produce the equation of state at high baryon chemical potentials above the crossover temperature at the physical point.
In large-Nc QCD at finite isospin density, an intermediate regime Lambda_QCD <= mu_I <= sqrt(Nc) Lambda_QCD hosts quarkyonic meson matter consisting of a filled Fermi sea of quarks bound into mesons on the QCD scale, possibly with surface Bose condensation or Cooper pairing.
Leading order chiral perturbation theory yields the minimal energy condition for vortex nucleation in the pion condensed phase, with vortices carrying quantized angular momentum and self-confining pions.
The IdylliQ model uses quark saturation to generate stiff equations of state and effective baryon repulsions that mitigate hyperon softening in neutron star matter.
A review of lattice QCD findings on the finite-temperature QCD transition at zero baryon chemical potential, its chiral limit behavior, constraints on the phase boundary and critical endpoint at finite density, plus advances under external fields and conditions.
