Complementarity of Gravitational Collapse (I) Origin of the Bekenstein-Hawking Entropy
Ding-fang Zeng
Through two exact solution families to Einstein equation and one-to-one correspondence between their free parameters, we show that the ensemble of collapsars with arbitrarily close…
Complementarity of Gravitation Collapse (II) XOB and the Damping Gravitational Waveform as Evidences
Ding-fang Zeng
This is the second paper of our working series on the complementarity of gravitational collapse. In this paper we prove that dynamics of XOB (an eXact One-Body Method) under the we…
Quasinormal modes of Reissner-Nordström-AdS black holes under physical field-vanishing boundary conditions
Hui-Fa Liu, Qi Su, Ding-fang Zeng
Boundary conditions play a key role in determining the perturbation behavior of a black hole. Motivated by two guiding principles for single-field perturbations -- the non-deformat…
Gravitational-Bumblebee perturbations: Exact decoupling and isospectrality
Hui-Fa Liu, Wentao Liu, Yu-Xiao Liu +2
In this paper, we present the exact decoupling of the full metric and bumblebee field perturbations in a Schwarzschild-like background. The coupled system reduces to four decoupled…
Propelling force from asymmetrically excited quantum vacuum with conventional mirrors
Yu-Song Cao, YanXia Liu, Ding-Fang Zeng
Investigations show that a time-varying mirror gives rise to asymmetrical vacuum radiation on its two sides, enabling one to extract propelling forces from the vacuum fluc…
