非对易高维黑洞的Parikh-Wilczek隧穿

Parikh-Wilczek Tunneling from Noncommutative Higher Dimensional Black Holes

Kourosh Nozari, S. Hamid Mehdipour

摘要:

我们研究了无质量粒子和有质量粒子通过额外维史瓦西黑洞的模糊量子视界的隧穿。粒子隧穿的发射率被尺寸为$d$的大块时空中的非对易性效应所修正。信息丢失和发射粒子之间可能的相关性的问题进行了讨论。我们表明,即使考虑非对易性和膜世界效应,至少在后期和计算中使用的近似值内,不同的蒸发模式之间没有相关性。然而,引入量子引力效应,如修改标准色散关系或推广海森堡不确定原理,导致发射粒子之间的相关性。虽然这些相关性的时间演化并不是微不足道的,但从黑洞出来的一部分信息可以保留在这些相关性中。另一方面,作为时空非对易性的一个著名结果,一部分信息可能保存在稳定的黑洞遗迹中。

英文摘要:

We study tunneling of massless and massive particles through the smeared quantum horizon of the extra-dimensional Schwarzschild black holes. The emission rate of the particles' tunneling is modified by noncommutativity effects in a bulk spacetime of dimension $d$. The issues of information loss and possible correlations between emitted particles are discussed. We show that even by considering both noncommutativity and braneworld effects, there is no correlation between different modes of evaporation at least at late-time and within approximations used in the calculations. However, incorporation of quantum gravity effects such as modification of the standard dispersion relation or generalization of the Heisenberg uncertainty principle, leads to the correlation between emitted particles. Although time-evolution of these correlations is not trivial, a part of information coming out of the black hole can be preserved in these correlations. On the other hand, as a well-known result of spacetime noncommutativity, a part of information may be preserved in a stable black hole remnant.
