AI 中文摘要
研究表明，在类似Boulware真空下自由落入Bañados-Teitelboim-Zanelli（BTZ）黑洞的原子，会在霍金温度\(T_{H}\)下发射具有普朗克谱的辐射。对于随机初始时刻制备的下落原子云，会产生类似霍金的热辐射。该辐射与相对等效原理有关，真空场模式相对于下落原子加速。通过量子光学方法能轻松描述原子-场相互作用，其中每个原子可视为探测器。尽管(2 + 1)维引力具有拓扑性质，但BTZ黑洞的热力学和辐射特性仍由适用于高维引力的近视界共形量子力学（CQM）普遍支配。这种普遍的共形行为在一般黑洞背景下的所有场中都有体现，并产生与光子辐射场相关的ħ熵\(S_{\mathcal P}\)，它模仿了贝肯斯坦-霍金熵\(S_{\mathrm{BH}} = A/4\)，与黑洞视界面积成正比且比例因子正确。
英文摘要
Atoms falling freely into a Bañados-Teitelboim-Zanelli (BTZ) black hole in a Boulware-like vacuum are shown to emit radiation with a Planck spectrum at the Hawking temperature $T_{H}$. This leads to thermal Hawking-like radiation for a cloud of falling atoms prepared with random initial times. Moreover, the radiation is related to the relative equivalence principle, with the vacuum field modes accelerated with respect to the falling atom. The physics of the atom-field interactions is most easily described within a quantum optics approach, where each atom can be interpreted as a detector. Despite the topological nature of gravity in $(2+1)$ dimensions, the thermodynamic and radiation properties of BTZ black holes are still universally governed by the same near-horizon conformal quantum mechanics (CQM) applicable to higher-dimensional gravity. This universal conformal behavior is exhibited by all fields in the background of generic black holes, and generates an HBAR entropy $S_{\mathcal P}$ associated with the photon radiation field that mimics the Bekenstein-Hawking entropy $S_{\mathrm{BH}}=A/4$, proportional to the black-hole horizon area, and with the correct $1/4$ proportionality factor.
