摘要:

在物理学的许多领域中,携带内禀角动量的波包传播通常受到自旋-轨道相互作用的影响。这是自旋霍尔效应背后的主要机制,该效应导致波包沿自旋依赖的轨迹运动。自旋霍尔效应已在若干实验中被观察到,包括凝聚态系统中的电子以及在非均匀光学介质中传播的光。类似效应也被预言会出现在非均匀引力场中传播的波包上。我们对引力自旋霍尔效应进行了简要介绍,重点强调其与光学中光的自旋霍尔效应之间的类比。此外,我们回顾了最有希望的天体物理途径,这些途径可能促成引力自旋霍尔效应的实验观测。

英文摘要:

In many areas of physics, the propagation of wave packets carrying intrinsic angular momentum is generally influenced by spin-orbit interactions. This is the main mechanism behind spin Hall effects, which result in wave packets following spin-dependent trajectories. Spin Hall effects have been observed in several experiments for electrons in condensed matter systems and for light propagating in inhomogeneous optical media. Similar effects have also been predicted for wave packets propagating in inhomogeneous gravitational fields. We give a brief introduction to gravitational spin Hall effects, emphasizing the analogies with the spin Hall effect of light in optics. Furthermore, we review the most promising astrophysical avenues that could lead to experimental observations of the gravitational spin Hall effect.
