论文摘要
我们研究了通过真空极化引起的量子场的反应和薄灰尘壳塌陷的共形异常。结果表明，倒塌过程的最终命运取决于壳的物理特性，包括其静止和重力质量。研究黑洞形成的条件，我们注意到量子效应改变了Schwarzschild时空的几何形状和结构，即黑洞具有两个视野，一个内部和外部地平线。如果壳的重力质量大约是普通恒星的重力，则在大多数情况下，半古典的崩溃将以奇异性终止，通常，量子波动不足以防止产生奇异性。尽管在某些条件下，可以形成一个非单明的黑洞，即常规黑洞。这样，倒塌的停止的半径比内部地平线下方的普朗克长度大得多，壳弹起并开始膨胀。
We study the backreaction of quantum fields induced through the vacuum polarization and the conformal anomaly on the collapse of a thin shell of dust. It is shown that the final fate of the collapse process depends on the physical properties of the shell, including its rest and gravitational masses. Investigating the conditions for the formation of black holes, we notice that quantum effects modify the geometry and structure of Schwarzschild space-time in such a way that black holes have two horizons, an inner and an outer horizon. If the gravitational mass of the shell is about that of an ordinary star, then in most cases, the semi-classical collapse will terminate in a singularity, and in general, quantum fluctuations are not strong enough to prevent the creation of the singularity. Although under certain conditions, it is possible to form a non-singular black hole, i.e., a regular black hole. In this way, the collapse stops at a radius much larger than the Planck length below the inner horizon, and the shell bounces and starts an expansion.
