非极端黑洞的超彭罗斯过程

Super-Penrose process for nonextremal black holes

O. B. Zaslavskii

摘要:

我们考虑在非极值球对称静态黑洞背景下的粒子碰撞。结果表明,碰撞碎片在无穷远处可以具有无限大的能量,即可以发生超彭罗斯过程(SPP)。这一性质与旋转黑洞的性质形成了鲜明的对比,对于旋转黑洞,SPP是被禁止的。Reissner-Nordstrom黑洞就是一个例子。如果有外力作用在粒子上,即使史瓦西背景也适用于SPP。

英文摘要:

We consider particle collisions in the background of nonextremal spherically symmetric static black holes. It is shown that debris of collision can have indefinitely large energy at infinity, i.e. the super-Penrose process (SPP) can occur. This property is sharply contrasted with that of rotating black holes for which it is already established that the SPP is forbidden. The Reissner-Nordstrom black hole serves as an example. If an external central force exerts on particles, even the Schwarzschild background is suitable for the SPP.
