论文摘要
在此简短说明中，我们使用kmoc形式主义和量子软定理分析了低能电磁辐射的旋转颗粒。特别是，我们研究了由所谓的$ \ sqrt {\ text {kerr}} $对象发出的低能电磁辐射。 $ \ sqrt {\ text {kerr}} $是免费的麦克斯韦方程的解决方案，其无限多极矩仅以经典对象的电荷（q），质量（m）和旋转（s）表示。我们考虑两个$ \ sqrt {\ text {kerr}} $粒子的散射，并使用kMoc形式主义推广到旋转粒子，我们扰动地证明了经典的subleding subread supread soft soft Photon定理，以在低deflection参数和$ \ mathcal参数和to $ \ mathcal {o} {o} {1} = 1} s_ {1} s_ {1} s_ {2} s_ {1} s_ {2} = {2} = {2} = {2} = {1} = {1} {2} {2} {2}
In this short note, we analyse low energy electromagnetic radiation for spinning particles using the KMOC formalism and the quantum soft theorems. In particular, we study low energy electromagnetic radiation emitted by the so-called $\sqrt{\text{Kerr}}$ object. The $\sqrt{\text{Kerr}}$ is a solution of the free Maxwell's equations with infinite multipole moments expressed solely in terms of the charge(Q), mass(m) and spin(S) of the classical object . We consider the scattering of two $\sqrt{\text{Kerr}}$ particles and using the KMOC formalism generalised to spinning particles, we perturbatively prove the classical subleading soft photon theorem to leading order in the low deflection parameter and to $\mathcal{O}(S_{1}S_{2})$ in spin.
