报告摘要

Black holes and gravitational waves are two important predictions of classical general relativity, and are thus the crucial tests of gravitation theories. In a rotating gravitational field produced by a Kerr black hole, the coupling between the macroscopic rotation of black hole and the angular momentum of photon can not only distort the orbital motion of the photon, and also produces an additional nor-integrable phase, leading to the wavefront distortion of the light coming from near the black hole. On the other hand, it was found that there is a dipole interaction between twisted lights and gravitational waves, which make photos undergoing dipole transitions between different orbital-angular-momentum eigenstates. In this talk, I will discuss these two effects and their astronomical implications, in particular the detection of strongest gravitational fields produced by spinning black holes and the weakest gravitational fields in gravitational waves.
