Generation of a bubble universe using a negative energy bath
Dong-il Hwang, Dong-han Yeom
This paper suggests a model for a bubble universe using buildable false vacuum bubbles. We study the causal structures of collapsing false vacuum bubbles using double-null simulati…

Internal structure of charged black holes
Dong-il Hwang, Dong-han Yeom
We investigate the internal structure of charged black holes with a spherically symmetric model in the double-null coordinate system. Hawking radiation is considered using the S-wa…

Responses of the Brans-Dicke field due to gravitational collapses
Dong-il Hwang, Dong-han Yeom
We study responses of the Brans-Dicke field due to gravitational collapses of scalar field pulses using numerical simulations. Double-null formalism is employed to implement the nu…
