Quantum geometry and effective dynamics of Janis-Newman-Winicour singularities
Cong Zhang, Xiangdong Zhang
Inspired by the recent proposal for the quantum effective dynamics of the Schwarzschild spacetime given in \cite{AOS1}, we investigate the effective dynamics of the loop quantized…

Loop quantum cosmology from an alternative Hamiltonian
Jinsong Yang, Cong Zhang, Yongge Ma
In this paper, a new Hamiltonian constraint operator for loop quantum cosmology is constructed by using the Chern-Simons action. The quantum dynamics of the cosmological mode…

Bouncing evolution in a model of loop quantum gravity
Cong Zhang, Jerzy Lewandowski, Haida Li +1
To understand the dynamics of loop quantum gravity, the deparametrized model of gravity coupled to a scalar field is studied in a simple case, where the graph underlying the spin n…
