论文摘要
研究了一个极端Banãdos-Teitelboim-Zanelli（BTZ）黑洞附近的Penrose过程。由于存在负宇宙常数，只有无质量的颗粒才能逃脱到无穷大。因此，我们通过一个无质量的粒子与BTZ黑洞地平线附近的另一个巨大粒子相撞分析了Penrose过程。对于无旋转颗粒和旋转颗粒，对此过程的最大能量提取效率进行了计算。我们的结果表明，旋转粒子的能量提取效率高于无旋转粒子。此外，我们的计算还表明，最大能量提取效率与BTZ黑洞的宇宙常数值无关。
The Penrose process in the vicinity of an extremal Banãdos-Teitelboim-Zanelli(BTZ) black hole is studied. Due to the existence of negative cosmological constant, only massless particles could escape to infinity. Hence we analyse the Penrose process by one massless particle collides with another massive particle near the horizon of BTZ black holes. Calculations of the maximum energy extraction efficiency of this process is carried out for both spinless and spinning particles. Our results show that the spinning particle have a higher energy extraction efficiency than the spinless particle. Moreover, our calculation also indicates that the maximum energy extraction efficiency is independent of the value of the cosmological constant of BTZ black holes.
