一般类Taub-NUT黑洞的模拟粒子产生模型

Analog Particle Production Model for General Classes of Taub-NUT Black Holes

Joshua Foo, Michael R. R. Good, Robert B. Mann

摘要:

我们导出了一般类Taub-NUT黑洞发射的霍金辐射谱与加速Dirichlet边界条件(即\一个完美的反射镜)在(1+1)维平坦时空。我们表明,粒子和能量谱是热在后期的时间和粒子生产被抑制的NUT参数。我们还计算了辐射光谱的旋转,带电(克尔-纽曼)Taub-NUT的情况下,和极端的情况下,明确显示这些参数如何影响传出的粒子和能量通量。

英文摘要:

We derive a correspondence between the Hawking radiation spectra emitted from general classes of Taub-NUT black holes with that induced by the relativistic motion of an accelerated Dirichlet boundary condition (i.e.\ a perfectly reflecting mirror) in (1+1)-dimensional flat spacetime. We demonstrate that the particle and energy spectra is thermal at late-times and that particle production is suppressed by the NUT parameter. We also compute the radiation spectrum in the rotating, electrically charged (Kerr-Newman) Taub-NUT scenario, and the extremal case, showing explicitly how these parameters affect the outgoing particle and energy fluxes.
