The effect of charge, isospin, and strangeness in the QCD phase diagram critical end point

Understand

In this work, we discuss the deconfinement phase transition to quark matter in hot/dense matter.

• We {examine} the effect that different charge fractions, isospin fractions, net strangeness, and chemical equilibrium with respect to leptons have on the position of the coexistence line between different phases.
• In particular, we investigate how different sets of conditions that describe matter in neutron stars and their mergers, or matter created in heavy-ion collisions affect the position of the critical end point, namely where the first-order phase transition becomes a crossover.
• We also present an introduction to the topic of critical points, including a review of recent {advances} concerning QCD critical points.
