摘要:
我们研究嵌入在外磁场中旋转介质里的带电费米子的电磁辐射。在强亚临界场中,针对费米子极化沿磁场方向和逆磁场方向两种情况,我们计算了辐射强度对角速度 $Ω$ 的依赖关系。光子辐射的极化依赖导致了索科洛夫–特尔诺夫效应——费米子的辐射极化。我们研究了极化度对 $Ω$ 的依赖关系。我们发现旋转会显著改变极化度。我们表明,旋转的夸克-胶子等离子体会获得一个有限的磁矩,该磁矩对 $Ω$ 表现出复杂的依赖关系。
英文摘要:
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 $Ω$.
