Families of regular spacetimes and energy conditions
Zi-Liang Wang, Emmanuele Battista
We present a systematic method for constructing static, spherically symmetric regular spacetimes of Kerr-Schild type in general relativity that satisfy the weak energy condition. O…
Shadows of quintessence black holes: spherical accretion, photon trajectories, and geodesic observers
Ji-Wen Li, Zi-Liang Wang, Tao-Tao Sui
The presence of a quintessence-like field can influence the black hole shadow through three primary mechanisms: the dynamics of accretion flows, the trajectories of photons, and th…
Energy conditions in static, spherically symmetric spacetimes and effective geometries
Zi-Liang Wang, Emmanuele Battista
Classical energy conditions are investigated in generic static and spherically symmetric spacetimes. In setups with nonconstant , the appearance of horizons can sign…
Exploring the role of accretion disk geometry in shaping black hole shadows
Zi-Liang Wang
We study black hole imaging in the context of geometrically thick accretion disks in Schwarzschild spacetime. By decomposing the emitting region into a set of one-dimensional lumin…
Dynamical features and shadows of quantum Schwarzschild black hole in effective field theories of gravity
Zi-Liang Wang, Emmanuele Battista
We investigate the properties of the Schwarzschild black hole geometry involving leading one-loop long-distance quantum effects, which arise within the framework of effective field…
The effect of scalar hair on the charged black hole with the images from accretions disk
Tao-Tao Sui, Zi-Liang Wang, Wen-Di Guo
In this paper, we investigate the optical properties of a charged black hole with scalar hair (CSH) within the context of four-dimensional Einstein-Maxwell-Dilaton gravity. To achi…
On a Schwarzschild-type defect wormhole
Zi-Liang Wang
We investigate a new type of Schwarzschild wormhole, which relies on a 3-dimensional spacetime defect with degenerate metrics. This particular wormhole is a solution of the vacuum…
Fate of homogeneous -symmetric scalar condensates
Wen-Yuan Ai, Zi-Liang Wang
Dark matter, if represented by a -symmetric scalar field, can manifest as both particles and condensates. In this paper, we study the evolution of an oscillating homo…
Shadows and rings of a de Sitter-Schwarzschild black hole
Zi-Liang Wang
We study the optical appearance of a de Sitter-Schwarzschild black hole and its distinguishability from a Schwarzschild black hole. By exploring various accretion models and emissi…
Dissipation of oscillating scalar backgrounds in an FLRW universe
Zi-Liang Wang, Wen-Yuan Ai
We study the dissipation of oscillating scalar backgrounds in a spatially flat Friedmann-Lemaître-Robertson-Walker universe using non-equilibrium quantum field theory. To be concre…
Conformal transformation route to gravity's rainbow
Miao He, Ping Li, Zi-Liang Wang +2
Conformal transformation as a mathematical tool has been used in many areas of gravitational physics. In this paper, we would consider the gravity's rainbow, in which the metric co…
Hawking radiation-quasinormal modes correspondence for large AdS black holes
Dao-Quan Sun, Zi-Liang Wang, Miao He +2
It is well-known that the non-strictly thermal character of the Hawking radiation spectrum generates a natural correspondence between Hawking radiation and black hole quasinormal m…
The generalization of charged AdS black hole specific volume and number density
Ziliang Wang, Miao He, Chao Fang +2
In this paper, by proposing a generalized , we restudy the criticality of charged AdS black holes in the extended phase space. The results show that most of…
Discussion of a possible corrected black hole entropy
Miao He, Zi-Liang Wang, Chao Fang +2
Einstein's equation could be interpreted as the first law of thermodynamic near the spherically symmetric horizon. Through recalling the Einstein gravity with a more general static…
A model of eternal accelerated expansion without particle horizon
Zi-Liang Wang, Jian-Bo Deng
In our previous paper \cite{8}, we proposed a cosmological model from the emergence of space, which possesses a significant character of evaluating the vacuum energy from the Hubbl…
A cosmological model from emergence of space
Zi-Liang Wang, Wen-Yuan Ai, Hua Chen +1
Many studies have been carried out since T.Padmanabhan proposed that the cosmic acceleration can be understood from the perspective that spacetime dynamics is an emergent phenomeno…
Quantum Cosmology via Quantization of Point-Like Lagrangian
Miao He, Zi-Liang Wang, Jian-Bo Deng +1
The purpose of this paper is to introduce a new way to inquire the quantum cosmology for a certain gravitational theory. Normally, the quantum cosmological model is introduced as t…
