Description
Extremely strong magnetic fields appear in high-energy heavy-ion collisions and compact stars like magnetars. Under such strong magnetic fields, photons and even hadrons show unusual behaviors. In this talk, I will explain photon's vacuum birefringence and decay into an e+e- pair [1,2] and the conversion of neutral pions into (virtual) photons [3] both of which are possible in strong magnetic fields. I will also discuss how these phenomena can manifest in heavy-ion collisions.
