Description
Synchrotron radiation (SR) is emitted by charged particles moving in magnetic fields and has numerous applications in many areas of physics. Often the charged particles are also part of a larger rotating system, e.g. the quark-gluon plasma and rotating stars. I will show that SR exhibits a remarkable sensitivity to the angular velocity of rotation. Additionally, the size of rapidly rotating systems is constrained by causality. I will show how to take account of causality by constructing quantum states in a finite volume, how this affects the SR in a rapidly rotating system and how the same formalism can be used to assess finite volume corrections to the chiral magnetic effect. I will argue that SR enhanced by rotation is a likely explanation for the direct photon puzzle in heavy-ion collisions.
