Thermodynamic Supercriticality and Complex Phase Diagram for Charged AdS Black Holes in Trace Anomaly Gravity
Minyan Ou, Xiangdong Zhang, Zhang-Yu Nie
We extend the Lee-Yang phase transition framework to charged anti-de Sitter (AdS) black holes in four-dimensional trace anomaly gravity. By treating the horizon radius as a complex…
Extended spherically symmetric solutions in revised Deser--Woodard nonlocal gravity
Haida Li, Xiangdong Zhang
In this work, we extend the static spherically symmetric black hole solutions of revised Deser--Woodard (D-W) nonlocal gravity. Due to the linearity of the field equations, we show…
Higher-dimensional quantum-corrected Oppenheimer-Snyder model with a cosmological constant
Shudi Jiang, Jianhui Lin, Xiangdong Zhang
We extended the higher-dimensional quantum Oppenheimer-Snyder model to the case with a cosmological constant. For AdS case, we discuss its thermodynamic properties in extend phase…
Loop Quantum Kaluza-Klein Cosmology and Inflation
Shengzhi Li, Yongge Ma, Faqiang Yuan +1
We present the detailed analyses of five-dimensional loop quantum Kaluza-Klein cosmology based on the symmetric reduction of the connection formulation of the full theory. The prev…
Effective Dynamics of Loop Quantum Kaluza-Klein Cosmology
Shengzhi Li, Yongge Ma, Faqiang Yuan +1
The five-dimensional loop quantum Kaluza-Klein cosmology is constructed based on the symmetric reduction of the connection formulation of the full theory. Through semiclassical ana…
Quantum Oppenheimer-Snyder models in loop quantum cosmology with Lorentz term
Minyan Ou, Xiangdong Zhang
A novel quantum black hole model is derived by incorporating the Lorentzian term within the loop quantum cosmology framework of the quantum Oppenheimer-Snyder (qOS) model. This mod…
