Abstract The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders
about the fundamental theory of nature at play in the extreme gravity regime, where the …

Very compact objects probe extreme gravitational fields and may be the key to understand
outstanding puzzles in fundamental physics. These include the nature of dark matter, the …

In this Letter, employing the generalized off-shell free energy, we treat black hole solutions
as defects in the thermodynamic parameter space. The results show that the positive and …

In this paper, we extend our previous work [D. Wu, Phys. Rev. D 107, 024024 (2023)
PRVDAQ 2470-0010 10.1103/PhysRevD. 107.024024] to the more general cases with a …

In this paper, which is of programmatic rather than quantitative nature, we aim to further
delineate and sharpen the future potential of the LISA mission in the area of fundamental …

In this paper, we investigate the topological numbers for the singly rotating Kerr black holes
in all dimensions and the four-dimensional Kerr-Newman black hole. We show that for …

In this work, we present a convenient method to perform the topological analysis of black
hole thermodynamics. Utilizing the spinodal curve, thermodynamic critical points of a black …

For ultra compact objects, light rings and fundamental photon orbits (FPOs) play a pivotal
role in the theoretical analysis of strong gravitational lensing effects, and of BH shadows in …

Recently, two types of static black hole models that retain general covariance have been
proposed within the Hamiltonian constraint approach to effective quantum gravity (EQG). We …
