Cosmological Evolution of the Randall-Sundrum II Model with Running Vacuum: A Special Class of Solutions
Hao Yu, Jin Li, Zi-Chao Lin
In this work, we construct a novel cosmological framework by integrating the running vacuum model into the Randall-Sundrum II braneworld scenario. We derive a special class of anal…
Qualitative Shadow Anomaly as a Smoking-gun Signature of Nonmetricity
Zi-Chao Lin, Hao Yu, Yu-Xiao Liu +1
In general relativity and its metric-formalism extensions, the innermost stable circular orbit and the photon ring of a charged black hole contract as the charge increases. In this…
The constraints on the stochastic gravitational wave background from cosmic strings by an electromagnetic resonance system
Jin Li, Meijin Li, Nan Yang +6
As one of the primary detection targets for contemporary gravitational wave (GW) observatories, the stochastic gravitational wave background (SGWB) holds significant potential for…
Shadows, Quasinormal Modes, and Optical Appearances of Black Holes in Horndeski Theory
Zhi Luo, Jin Li, Ke-Jian He +1
This work describes the motion of photons in black hole (BH) spacetimes within the framework of Horndeski theory. We focus on the shadows, quasinormal modes (QNMs) and optical appe…
Holographic entropy bound and a special class of spherical systems in cosmology
Hao Yu, Zi-Chao Lin, Jin Li
The holographic entropy bound is discussed in cosmology. Inspired by the work of Fischler and Susskind [hep-th/9806039], we aim to define a special class of spherical systems in co…
Observational appearance and additional photon rings of the asymmetric thin-shell wormhole in Horndeski theory
Zhi Luo, Hao Yu, Jin Li
In this paper, we study the observational appearance of the asymmetric thin-shell wormhole (ATW) in Horndeski theory by employing the ray-tracing method. We first calculate the eff…
Electromagnetic counterparts of high-frequency gravitational waves in a rotating laboratory frame system and their detection
Fang-Yu Li, Hao Yu, Jin Li +2
We consider the perturbative photon flows (PPFs, i.e., electromagnetic (EM) counterparts) generated by the EM resonance response to high-frequency gravitational waves (HFGWs) with…
Using entropy bounds to avoid the cosmological singularity and constrain cosmological particle production
Hao Yu, Jin Li
In this work, we study the applications of entropy bounds in two toy cosmological models with particle production (annihilation), i.e., a radiation-dominated universe and a dust-do…
Shadow thermodynamics of the Hayward-AdS black hole
Zhi Luo, Hao Yu, Shuo Cao +1
In this paper, the phase structure of the Hayward-AdS black hole (BH) is studied using shadow formalism. It has been found that the shadow radius is a monotonic function of the hor…
Effects of a global monopole on thermodynamic phase transition of the charged AdS black hole
Zhi Luo, Hao Yu, Jin Li
In this paper, we study the dynamical properties of thermodynamic phase transition (PT) for the charged AdS black hole (BH) with a global monopole via the Gibbs free energy landsca…
Entropies of the various components of the universe
Hao Yu, Yu-Xiao Liu, Jin Li
In this work, we study the entropies of photons, dust (baryonic matter), dark matter, and dark energy in the context of cosmology. When these components expand freely with the univ…
On the correspondence between energy conservation and energy-momentum tensor conservation in cosmology
Hao Yu, Bao-Min Gu, Zhi Luo +1
The correspondence between the thermodynamic energy equation satisfied by a closed co-moving volume and the conservation equation satisfied by the energy-momentum tensor of the mat…
Constraints on running vacuum models with the baryon-to-photon ratio
Hao Yu, Ke Yang, Jin Li
We study the influence of running vacuum on the baryon-to-photon ratio in running vacuum models (RVMs). When there exists a non-minimal coupling between photons and other matter in…
