Black holes with conical infinity in gravitational caloric theory
S. X. Tian, Zong-Hong Zhu
Whether gravitational caloric theory admits spherical black-hole solutions beyond Schwarzschild remains open. A well-defined black-hole solution requires both a regular horizon and…
Measuring the Moving Lens Effect with Wide-Separation Lensed Quasars
Yupeng Zhang, Shuxun Tian, Zhengxiang Li
The transverse motion of a gravitational potential induces frequency shifts in photons propagating through it, giving rise to the moving-lens effect and providing a probe of transv…
Gravitational caloric theory: From early dark energy to a wide variety of gravitational phenomena
S. X. Tian
We propose gravitational caloric theory (GCT) --- an extension of general relativity that features a vector field sourced by and non-minimally coupled to the fluid sector whi…
Inflation driven by a bare cosmological constant and its graceful exit
Chengsheng Mu, Shuxun Tian, Shuo Cao +1
Vacuum energy, a prediction of quantum field theory, manifests itself as a cosmological constant in general relativity. In this Letter, we propose a novel inflationary scenario dri…
Testing Screened Modified Gravity with Strongly Lensed Gravitational Waves
Chengsheng Mu, Shuo Cao, Shuxun Tian +3
Screening mechanisms are essential components in many modified gravity theories, which satisfy local tests of General Relativity (GR) and address cosmic acceleration on cosmologica…
Avoiding recollapse in an open-AdS universe via a self-tuning-like mechanism
Yupeng Zhang, Shuxun Tian, Zhengxiang Li
We study whether an open FLRW universe with a negative cosmological constant can evade the eventual recollapse characteristic of an AdS-type universe. Within a power-law realizatio…
