Wheeler-DeWitt equation rejects quantum effects of grown-up universes as a candidate for dark energy
Dongshan He, Qing-yu Cai
In this paper, we study the changes of quantum effects of a growing universe by using Wheeler-DeWitt equation (WDWE) together with de Broglie-Bohm quantum trajectory approach. From…
Gravitational correlation, black hole entropy and information conservation
Dongshan He, Qing-yu Cai
When two objects have gravitational interaction between them, they are no longer independent of each other. In fact, there exists gravitational correlation between these two object…
Dynamical interpretation of the wavefunction of the universe
Dongshan He, Dongfeng Gao, Qing-yu Cai
In this paper, we study the physical meaning of the wavefunction of the universe. With the continuity equation derived from the Wheeler-DeWitt (WDW) equation in the minisuperspace…
Inflation of small true vacuum bubble by quantization of Einstein-Hilbert action
Dongshan He, Qing-yu Cai
We study the quantization of the Einstein-Hilbert action for a small true vacuum bubble without matter or scalar field. The quantization of action induces an extra term of potentia…
Spontaneous creation of the universe from nothing
Dongshan He, Dongfeng Gao, Qing-yu Cai
An interesting idea is that the universe could be spontaneously created from nothing, but no rigorous proof has been given. In this paper, we present such a proof based on the anal…
