We study electromagnetic radiation by electrically charged fermions embedded in a rotating medium in an external magnetic field. We compute the dependence of the radiation intensity on the angular velocity $\mathrm{\Omega }$ of the rotating medium for fermion polarizations along and opposite the magnetic field direction in intense subcritical fields. The polarization dependence of the photon radiation results in the Sokolov-Ternov effect—the radiative polarization of fermions. We study the dependence of the degree of polarziation on $\mathrm{\Omega }$ . We found that rotation significantly changes the degree of polarization. We show that the rotating quark-gluon plasma acquires a finite magnetic moment that exhibits complex dependence on $\mathrm{\Omega }$ . Published by the American Physical Society 2025
