Holomorphic Conformal Cartan Geometry: Conformal Gravity, Twistors, and Ambitwistors
Chen-Hsu Chien
Four-dimensional conformal gravity, twistor theory, and ambitwistor theory are reviewed within the unified framework of holomorphic conformal Cartan geometry. Starting from the spi…
Quantum Suppression of Mass Inflation in Reissner-Nordström Interiors via Wheeler-DeWitt Equation
Chen-Hsu Chien, Woosung Song, Gansukh Tumurtushaa +1
We construct a canonical quantization, the Wheeler-DeWitt equation, of the interior geometry of static and spherically symmetric black holes in Einstein-Maxwell- framework, focu…
Wheeler-DeWitt equation beyond the cosmological horizon: Annihilation to nothing, infinity avoidance, and loss of quantum coherence
Chen-Hsu Chien, Gansukh Tumurtushaa, Dong-han Yeom
We investigate the Schwarzschild-(anti) de Sitter spacetime with the anisotropic metric ansatz. The Wheeler-DeWitt equation for such a metric is solved numerically. In the presence…
The reheating constraints to natural inflation in Horndeski gravity
Chen-Hsu Chien, Seoktae Koh, Gansukh Tumurtushaa
For the subclass of Horndeski theory of gravity, we investigate the effects of reheating on the predictions of natural inflation. In the presence of derivative self-interaction of…
