AI总结:

本研究验证了径向落入无自旋BTZ黑洞、与Hartle-Hawking态标量场耦合的UDW探测器跃迁速率在视界附近存在局部极值,给出相关数值结果,证实该效应的鲁棒性,为后续黑洞时空相关研究提供支撑。

摘要:

近期研究表明,径向落入四维史瓦西黑洞的Unruh-DeWitt(UDW,昂鲁-德威特)探测器,当它与制备在Hartle-Hawking(哈特尔-霍金)态或Unruh(昂鲁)态的无质量标量场线性耦合时,其跃迁概率在黑洞视界附近会呈现局部极值[K.K. Ng等人,《New J. Phys.》24卷(2022)103018]。我们发现,在径向落入无自旋Bañados-Teitelboim-Zanelli(BTZ,巴尼奥斯-泰特尔鲍姆-萨内利)黑洞的UDW探测器的跃迁速率中,也存在类似现象,其中标量场制备在Hartle-Hawking态。我们给出了随探测器能隙、黑洞质量以及探测器释放半径变化的大量数值结果。我们的结果表明该效应具有鲁棒性,这推动了在其他黑洞时空中寻找类似效应的研究,也呼吁对该效应的物理起源做出解释。

英文摘要:

An Unruh-DeWitt (UDW) detector falling radially into a four-dimensional Schwarzschild black hole, coupled linearly to a massless scalar field that has been prepared in the Hartle-Hawking or Unruh state, has recently been shown to exhibit a local extremum in its transition probability near the black hole horizon [K.K. Ng et al., New J. Phys. 24 (2022) 103018]. We show that a similar phenomenon is present in the transition rate of a UDW detector falling radially into a spinless Bañados-Teitelboim-Zanelli (BTZ) black hole, with the scalar field prepared in the Hartle-Hawking state. We give extensive numerical results as a function of the detector's energy gap, the black hole's mass, and the detector's drop-off radius. Our results suggest that the effect is robust, motivating a search for a similar effect in other black hole spacetimes, and calling for an explanation of the physical origin of the effect.
