近日，印度校际天文与天体物理中心的Rajendra Prasad Bhatt及其研究团队取得一项新进展。经过不懈努力，他们揭示了旋转BTZ黑洞的标量潮汐响应。相关研究成果已于2024年11月27日在国际知名学术期刊《高能物理杂志》上发表。

该研究团队研究了旋转BTZ（Banados-Teitelboim-Zanelli）黑洞对标量潮汐扰动的响应。研究人员发现潮汐响应函数的实部不为零，这表明旋转BTZ黑洞具有非零的潮汐洛夫数。

研究人员还观察到潮汐响应函数中存在一种，称为对数运行（log-running）的尺度依赖行为。研究人员对极端旋转BTZ黑洞进行了单独分析，发现其与非极端情况在定性上具有相似性。此外，研究人员还提出了一种计算带电旋转BTZ黑洞潮汐响应函数的方法。

Abstract: We study the response of a rotating BTZ black hole to the scalar tidal perturbation. We show that the real component of the tidal response function isn’t zero, indicating that a rotating BTZ black hole possesses non-zero tidal Love numbers. Additionally, we observe scale-dependent behaviour, known as log-running, in the tidal response function. We also conduct a separate analysis on an extremal rotating BTZ black hole, finding qualitative similarities with its non-extremal counterpart. In addition, we present a procedure to calculate the tidal response function of a charged rotating BTZ black hole as well.
