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…
