The effect of the tortoise coordinates on the tunnel effect
Tian Gui-hua, Zhao Zheng, Shi-kun Wang
The tunnel process of the quantum wave from the light cone is carefully discussed. They are applied in the massive quantum particles from the Schwarzschild black hole in the Kruska…

Reconsideration of the Regge-Wheeler equation
Guihua Tian, Shikun Wang, Zhao Zheng
Reconsideration of the Regge-Wheeler equation is processed by using the Painlevé coordinate and "good" timelier to define the initial time. We find that: the Regge-Wheeler equation…

Is the Schwarzschild black hole really stable?
Guihua Tian, Shikun Wang, Zhao Zheng
The stability of the Schwarzschild black hole is studied. Regge and Wheeler treated the problem first at 1957 and obtained the dynamical equations for the small perturbation. There…
