Quantum gravitational effects in de Sitter space | | Claus Kiefer
; | | Date: |
2 Dec 1994 | | Subject: | gr-qc | | Abstract: | We calculate the first quantum gravitational correction term to the trace anomaly in De Sitter space from the Wheeler-DeWitt equation. This is obtained through an expansion of the full wave functional for gravity and a conformally coupled scalar field in powers of the Planck mass. We also discuss a quantum gravity induced violation of unitarity and comment on its possible relevance for inflation. | | Source: | arXiv, gr-qc/9501001 | | Services: | Forum | Review | PDF | Favorites | |
