The Hubble tension: A decade review
Rong-Gen Cai, Shao-Jiang Wang
Ever since the new millennium, precision cosmology has forged the -cold-dark-matter (CDM) model as the standard model of concordant cosmology, withstanding various tests exce…
Can Distance Duality Violation Save Late-time Solutions to the Hubble Tension?
Yashi Tiwari, Ujjwal Upadhyay, Shao-Jiang Wang +1
The discrepancy between early- and late-Universe determinations of the Hubble constant may point to physics beyond CDM or to unaccounted-for systematics. Numerous late-time modi…
Nonminimally coupled quintessence with sign-switching interaction
Jia-Qi Wang, Rong-Gen Cai, Zong-Kuan Guo +3
We propose a new nonminimally coupled quintessence model to account for the late-time dark energy dynamics indicated by recent Dark Energy Spectroscopic Instrument (DESI) measureme…
Vacuum bubbles from cosmic ripples
Zi-Yan Yuwen, Rong-Gen Cai, Shao-Jiang Wang
We investigate vacuum decays in the early Universe in the presence of curvature perturbations. For sufficiently large perturbations associated with over-densities, we find that the…
Thermodynamics of Kerr-Bertotti-Robinson black hole
Li Hu, Rong-Gen Cai, Shao-Jiang Wang
We investigate the thermodynamic properties of the Kerr-Bertotti-Robinson black hole, an exact Petrov type-D solution of Einstein-Maxwell theory describing a rotating black hole im…
Prospect on constraining environment-dependent dilaton model from gravitational redshift measurements
Li Hu, Rong-Gen Cai, Song He +4
Scalar-tensor gravity represents a natural extension of general relativity. This paper investigates a conformal scalar-tensor gravity, the environmentally dependent dilaton model,…
Black hole-de Sitter space as the fastest transmitter and receiver
Rong-Gen Cai, Li Hu, Shao-Jiang Wang
It is well-known that the unitary nature of black hole evaporation enforces its entropy evolution to follow the Page curve. In this Letter, we find that the quantum speed limit on…
Fundamental Physics and Cosmology with TianQin
Jun Luo, Haipeng An, Ligong Bian +33
The exploration of the surrounding world and the universe is an important theme in the legacy of humankind. The detection of gravitational waves is adding a new dimension to this g…
Dynamical friction can flip the hierarchical three-body system
Li Hu, Rong-Gen Cai, Shao-Jiang Wang
In recent years, the long-term effects of non-linear perturbations were found to be important for the evolution of the hierarchical triple system, which, for the central third body…
Bubbles kick off primordial black holes to form more binaries
Zi-Yan Yuwen, Cristian Joana, Shao-Jiang Wang +1
Primordial black holes (PBHs) may form before cosmological first-order phase transitions, leading to inevitable collisions between PBHs and bubble walls. In this Letter, we have si…
Multiple peaks in gravitational waves induced from primordial curvature perturbations with non-Gaussianity
Xiang-Xi Zeng, Rong-Gen Cai, Shao-Jiang Wang
First-order primordial curvature perturbations are known to induce gravitational waves at the second-order, which can in turn probe the small-scale curvature perturbations near the…
Distinctive GWBs from eccentric inspiraling SMBH binaries with a DM spike
Li Hu, Rong-Gen Cai, Shao-Jiang Wang
Recent detections of a low-frequency gravitational wave background (GWB) from various pulsar-timing-array (PTA) observations have renewed the interest in the inspiraling supermassi…
The doomsday of black hole evaporation
Shao-Jiang Wang
By assuming simultaneously the unitarity of the Hawking evaporation and the universality of Bekenstein entropy bound as well as the validity of cosmic censorship conjecture, we fin…
Hydrodynamic sound shell model
Rong-Gen Cai, Shao-Jiang Wang, Zi-Yan Yuwen
For a cosmological first-order phase transition in the early Universe, the associated stochastic gravitational wave background is usually dominated by sound waves from plasma fluid…
Bubble expansion at strong coupling
Li Li, Shao-Jiang Wang, Zi-Yan Yuwen
The cosmological first-order phase transition (FOPT) can be of strong dynamics but with its bubble wall velocity difficult to be determined due to lack of detailed collision terms.…

The current LIGO-Virgo observing run has been pushing the sensitivity limit to touch the stochastic gravitational-wave backgrounds (SGWBs). However, no significant detection has be…
Primordial black holes and induced gravitational waves from double-pole inflation
Chengjie Fu, Shao-Jiang Wang
The primordial black hole (PBH) productions from the inflationary potential with an inflection point usually rely heavily on the fine-tuning of the model parameters. We propose in…
Gravitational Waves and Primordial Black Hole Productions from Gluodynamics by Holography
