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 Janis-Newman-Winicour spacetime
Faqiang Yuan, Shengzhi Li, Zhen Li +1
The effective dynamics of the Janis-Newman-Winicour spacetime inspired by loop quantum gravity is studied. Two different schemes are considered to regularize the Hamiltonian constr…
Loop Quantum Vector-Tensor Gravity and Its Spherically Symmetric Model
Shengzhi Li, Yongge Ma
The Hamiltoinian analysis of the vector-tensor theory of gravity is performed. The resulting geometrical dynamics is reformulated into the connection dynamics, with the real SU(2)-…
Deparametrization and quantization of scalar-tensor gravity and its cosmological model
Faqiang Yuan, Haida Li, Shengzhi Li +1
The degree of freedom of the scalar field in scalar-tensor gravity is employed as "time" to deparametrize the Hamiltonian constraint of the theory. The deparametrized system is the…
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…
Geometrical Quantum Time in the Model of Euclidean Quantum Gravity
Sepideh Bakhoda, Yongge Ma
Loop Quantum Gravity faces challenges in constructing a well-defined Hamiltonian constraint and understanding the quantum notion of time. In this paper these issues are studied by…
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…
