Cold and dense perturbative QCD in a very strong magnetic background

We compute the pressure from first principles within perturbative QCD at finite baryon density and very high magnetic fields up to two-loops and with physical quark masses. The region of validity for our framework is given by \(m_s \ll \mu_q \ll \sqrt{eB}\), where \(m_s\) is the strange quark mass,...
