薛定谔形式、黑洞视界和奇点行为

Schrodinger formalism, black hole horizons and singularity behavior

John E. Wang, Eric Greenwood, Dejan Stojkovic

摘要:

用Gauss-Codazzi方法讨论了带电Reisner-Nordström畴壁的引力坍缩.我们求解了带电薄壳在自身引力场影响下运动的经典运动方程,并证明了一种形式的宇宙审查适用。如果坍缩壳层的电荷大于它的质量,那么坍缩就不会形成黑洞。相反,在达到某个最小半径后,壳反弹回来。利用薛定谔正则形式描述了带电壳层的运动。探讨了视界附近和奇点附近的极限。在视界附近,描述坍缩壳层演化的薛定谔方程表现为质量依赖于位置的质量波方程。解的输出和输入模式通过精确给出霍金温度的Bogolubov变换联系起来。在经典奇点附近,薛定谔方程变为非定域的,但描述系统的波函数是非奇异的。这表明,虽然量子效应可能能够消除经典奇异性,但它也可能引入一些新的效应。

英文摘要:

The Gauss-Codazzi method is used to discuss the gravitational collapse of a charged Reisner-Nordström domain wall. We solve the classical equations of motion of a thin charged shell moving under the influence of its own gravitational field and show that a form of cosmic censorship applies. If the charge of the collapsing shell is greater than its mass, then the collapse does not form a black hole. Instead, after reaching some minimal radius, the shell bounces back. The Schrodinger canonical formalism is used to quantize the motion of the charged shell. The limits near the horizon and near the singularity are explored. Near the horizon, the Schrodinger equation describing evolution of the collapsing shell takes the form of the massive wave equation with a position dependent mass. The outgoing and incoming modes of the solution are related by the Bogolubov transformation which precisely gives the Hawking temperature. Near the classical singularity, the Schrodinger equation becomes non-local, but the wave function describing the system is non-singular. This indicates that while quantum effects may be able to remove the classical singularity, it may also introduce some new effects.
