Abstract

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 Ω 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 Ω. 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 Ω.

旋转系统中的Sokolov-Ternov效应

我们研究电磁辐射的带电费米子嵌入旋转介质在一个外部磁场。我们计算了辐射强度对旋转介质沿磁场方向和反磁场方向费米子极化的角速度Ω的依赖关系。光子辐射的偏振依赖性导致了索科洛夫-特诺夫效应——费米子的辐射极化。我们研究了偏振度对Ω的依赖关系。我们发现旋转显著地改变了极化的程度。我们证明旋转的夸克-胶子等离子体获得一个有限磁矩，该磁矩表现出对Ω的复杂依赖。2025年由美国物理学会出版
