Quasiclassical approximation of electromagnetic radiation by fermions embedded in a rigidly rotating medium in a strong magnetic field

We develop the quasiclassical (WKB) approximation of the synchrotron radiation by a fermion embedded into a uniformly rotating system in external magnetic field. We show that it gives an accurate approximation of the exact expression that we recently obtained at a tiny fraction of the numerical cost. Our results can be used to compute the electromagnetic radiation of the quark-gluon plasma produced in relativistic heavy-ion collisions.
