论文摘要
众所周知，黑洞在探测强场状态中重力的量子效应方面起着重要作用。在本文中，我们专注于聚合的黑洞，并研究了对围绕这个黑洞旋转的巨大颗粒发出的光子的红移，蓝光和重力红移的量子效应。有了一般的相对论形式主义，我们就以很少的直接可观察物的形式获得了两个优雅而简洁的表达式和量子参数，并发现光子的所有频率移动都随量子参数而降低。通过扩大发射极大轨道的总频移，低特征性的红移和较小的方位角，我们发现对频移的主要贡献源于运动学移位和奇特的偏移，量子效应使得可忽略不计。此外，我们首次研究了血浆对红移/蓝光的影响，并得出结论，血浆的存在导致红移/蓝光的降低。
As is well-known, black hole plays an important role in probing the quantum effects of gravity in the strong-field regime. In this paper, we focus on a polymerized black hole and investigate the quantum effects on the redshift, blueshift and gravitational redshift of photons emitted by massive particles revolving around this black hole. With a general relativistic formalism, we obtain two elegant and concise expressions for the mass of the black hole and the quantum parameter in terms of few direct observables, and find that all the frequency shifts of photons decrease with the quantum parameter. By expanding the total frequency shift for large orbit of the emitter, low peculiar redshift, and small azimuthal angle, we find that the leading contributions to the frequency shift are originated from the kinematic shift and peculiar shift, and the quantum effects make a negligible contribution. In addition, we study the effects of the plasma on the redshift/blueshift for the first time, and conclude that the presence of plasma results in the decrease of the redshift/blueshift.
