Hongya Liu, Qiuyang Zhang
We study a time-dependent and spherically-symmetric solution with a star-like source. We show that this solution can be interpreted as an exterior solution of a contracting star wh…

Quantum Effects of an Extra Compact Dimension on the Wave Function of the Universe
Guowen Peng, Hongya Liu, Qiuyang Zhang
We extend the direct quantum approach of the standard FRW cosmology from 4D to 5D and obtain a Hamiltonian formulation for a wave-like 5D FRW cosmology. Using a late-time approxima…
