Distance between collapsing matter and trapping horizon in evaporating black holes
Pei-Ming Ho, Yoshinori Matsuo, Yuki Yokokura
Assuming that the vacuum energy-momentum tensor is not exceptionally large, we consider 4D evaporating black holes with spherical symmetry and evaluate the proper distance bet…
An Analytic Description of Semi-Classical Black-Hole Geometry
Pei-Ming Ho, Yoshinori Matsuo, Yuki Yokokura
We study analytically the spacetime geometry of the black-hole formation and evaporation. As a simplest model of the collapse, we consider a spherical thin shell, and take the back…
Trapping Horizon and Negative Energy
Pei-Ming Ho, Yoshinori Matsuo
Assuming spherical symmetry and the semi-classical Einstein equation, we prove that, for the observers on top of the trapping horizon, the vacuum energy-momentum tensor is always t…
Vacuum Energy at Apparent Horizon in Conventional Model of Black Holes
Pei-Ming Ho, Yoshinori Matsuo, Shu-Jung Yang
For a black hole of Schwarzschild radius , we argue that the back-reaction of the vacuum energy-momentum tensor is in general important at the apparent horizon when the time sca…
Asymptotic States of Black Holes in KMY Model
Pei-Ming Ho, Yoshinori Matsuo, Shu-Jung Yang
Following the work of Kawai, Matsuo, and Yokokura, we study the dynamical collapsing process with spherical symmetry in the time-dependent space-time background including the back…
