中文摘要: |
电磁波可以和物质发生相互作用,从而表现出力学效应,此外也可以向物质传递角动量,该角动量可以分为两部分即自旋角动量与轨道角动量。具有OAM的电磁波有一些特殊的结构与性质。从Riemann-Silberstein向量入手,可以得到带OAM电磁波的形式。利用洛伦兹力计算,可分析OAM电磁波对带电粒子运动的影响。介绍部分OAM电磁波产生方式例如螺旋相位板,克尔黑洞时空对光束进行影响等等。将其类比到引力波问题上,可以通过旋量形式与电磁波进行对应,从而得到OAM引力波的形式。通过测地偏差方程,可以分析OAM引力波对实物粒子的动力学效应。文中最后对OAM引力波的生成提出一些理论与猜想,例如双星绕转并合产生、克尔黑洞时空对引力波扰动生成。

外文摘要: |
Electromagnetic waves can interact with matter to exhibit mechanical effects? it can also transfer angular momentum to matter. The angular momentum can be divided into spin angular momentum and orbital angular momentum(OAM). Electromagnetic waves with OAM have some special structures and properties. Starting from the Riemann-Silberstein vector, the form of electromagnetic waves with OAM can be obtained. Using Lorentz force calculations, the influence of OAM electromagnetic waves on charged particles can be analyzed. Introduce some OAM electromagnetic wave generation methods, such as spiral phase plate, the influence of Kerr black hole on light beam, etc. By analogy to the problem of gravitational waves, the spinorial formalism can be used to correspond to electromagnetic waves, and the form of OAM gravitational waves can be obtained. Through the geodetic deviation equation, the dynamic effects of OAM gravitational waves on particles can be analyzed. Finally, some theories and conjectures are proposed for the generation of OAM gravitational waves, such as the generation of binary stars revolving and merging, and the generation of gravitational waves perturbed by Kerr black hole space-time.
