具有扭转和自旋的真空中的电磁波
Electromagnetic Waves in the Vacuum with Torsion and Spin
摘要：
真空中经典齐次麦克斯韦方程组的精确辐射波解是非横的，既有挠率又有自旋，并且第二个庞加莱不变量E.B不为零。在拓扑基上构造了自旋流和挠率的两个四分量秩3张量。每个伪矢量的发散产生电磁系统的庞加莱不变量。
英文摘要：
Exact radiative wave solutions to the classical homogeneous Maxwell equations in the vacuum have been found that are not transverse, exhibit both torsion and spin, and for which the second Poincare invariant, E.B, is not zero. Two four component rank 3 tensors of spin current and torsion are constructed on topological grounds. The divergence of each pseudo vector generates the Poincare invariants of the electromagnetic system.
