The effect of gravitational spin-orbit coupling on the circular photon orbit in the Schwarzschild geometry

Zhi-Yong Wang, Cai-Dong Xiong, Qi Qiu +2

The (1, 0)+(0, 1) representation of the group SL(2, C) provides a six-component spinor equivalent to the electromagnetic field tensor. By means of the (1, 0)+(0, 1) description, on…
