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…
Mass inflation and strong cosmic censorship conjecture in the covariant quantum black hole
Jianhui Lin, Xiangdong Zhang, Moisés Bravo-Gaete
Recently, two types of solutions to the long-standing issue of general covariance in canonical quantum gravity have been proposed. From the above, a fundamental question arises: wh…
Higher-dimensional quantum Oppenheimer-Snyder model
Zijian Shi, Xiangdong Zhang, Yongge Ma
The quantum Oppenheimer-Snyder model for higher-dimensional spacetimes is studied. The higher-dimensional quantum-corrected Schwarzschild black hole is obtained by the junction con…
