本研究求解了 Kiselev 黑洞背景下的 Klein-Gordon 方程，计算了能量准谱、霍金辐射与温度，发现 quintessence 类各向异性流体越强则辐射越弱，无 quintessence 时恢复史瓦西黑洞的霍金温度。
AI 中文摘要
本工作精确研究了被 quintessence 类各向异性流体（即 Kiselev 黑洞）环绕的静态不带电黑洞对相对论性无自旋粒子动力学的影响。以两个 quintessence 类模型为例，我们计算了径向波函数，确定了两种情况下的能量准谱，以及霍金辐射和温度。我们发现，quintessence 类各向异性流体的影响越强，事件视界外观测到的辐射越小。此外，两种情况下得到的温度均直接受 quintessence 类各向异性流体影响，且我们恢复了其他情境下（如用表面引力推导的情境）得到的数值。最后，在无 quintessence 的情况下，两种情况均恢复了对应史瓦西黑洞的霍金温度 $T_{H} = 1/(8\pi k_{B} M)$。
英文摘要
In this work, we investigate exactly the dynamics of a relativistic spinless particle influenced by a static and uncharged black hole surrounded by a quintessence-like anisotropic fluid or Kiselev black hole. Considering two quintessence-like models as examples, we calculate the radial wave function and determine, in both cases, the quasispectrum of energy, as well as the Hawking radiation and temperature. We find that the stronger the influence of quintessence-like anisotropic fluid, the smaller the radiation observed outside the event horizon. Furthermore, the temperatures obtained in both cases are directly influenced by the quintessence-like anisotropic fluid, and we recover the values obtained in other contexts, such as those derived using the surface gravity. Finally, in the absence of quintessence, we recover in both cases the Hawking temperature $T_{H} = 1/(8πk_{B} M)$ corresponding to the Schwarzschild black hole.
