Magnetic fields explicitly break the non-singlet flavour symmetry of QCD, since the light quarks carry unequal electric charges. The conventional mesonic partner relations used to diagnose chiral and $U(1)_A$ restoration at vanishing field must therefore be reconsidered before they can be applied at $eB \neq 0$. We show that the neutral channels retain this diagnostic role: the splitting...

We investigate the $U(1)_{A}$ symmetry and the chiral separation effect (CSE) in the presence of a strong background magnetic field within the three-flavor Nambu-Jona-Lasinio (NJL) model. To incorporate the inverse magnetic catalysis (IMC) effect, we introduce a magnetic-field-dependent scalar coupling $G_{s}(eB)$. We evaluate the susceptibility splittings $\chi_{\pi_{0}}-\chi_{\delta_{0}}$...

When describing particle collisions, we usually approximate the initial-state particles as plane waves. The fact that in reality they are wave packets does not usually play any role. However, the past two decades witnessed the emergence of a new intriguing class of wave packets called vortex states. A photon, an electron, or any other particle prepared in a vortex state is characterized by...
