Description
We compute the QCD pressure from first principles within perturbative QCD at very high magnetic fields up to next-to-leading in two different scenarios: hot quark matter and cold and dense quark matter.
We study the converge of the perturbative series for the pressure for different choices of medium dependent running coupling.
In the case of hot quark matter, we also calculate the chiral condensate and strange quark number susceptibility and the results are compared with lattice QCD data.
In the context of cold and dense quark matter, we identify a notable simplification arising from the effectively negligible contribution of the exchange diagram, which allows the building of a simple analytic model for the equation of state for pure quark magnetars and computing their mass and radius at very large values of $B$. These results provide constraints on the
behavior of the maximum mass and associated radius from perturbative QCD.
