Loop quantum cosmological model from ADM Hamiltonian
You Ding, Xiangdong Zhang
The loop quantum cosmological model from ADM Hamiltonian is studied in this paper. We consider the spatially flat homogeneous FRW model. It turns out that the modified Friedmann eq…
2+1 dimensional loop quantum cosmology of Bianchi I models
You Ding, Xiangdong Zhang
We study the anisotropic Bianchi I loop quantum cosmology in 2+1 dimensions. Both the $\mubar$ and $\mubar'$ schemes are considered in the present paper and the following expected…
Lorentzian spinfoam propagator
Eugenio Bianchi, You Ding
The two-point correlation function is calculated in the Lorentzian EPRL spinfoam model, and shown to match with the one in Regge calculus in a proper limit: large boundary spins, a…
On the Asymptotics of Quantum Group Spinfoam Model
You Ding, Muxin Han
Recently a quantum group deformation of EPRL spinfoam model was proposed in arXiv:1012.4216 by one of the authors, and in arXiv:1012.4784 by Fairbairn and Meusburger. It is interes…
Generalized Spinfoams
You Ding, Muxin Han, Carlo Rovelli
We reconsider the spinfoam dynamics that has been recently introduced, in the generalized Kaminski-Kisielowski-Lewandowski (KKL) version where the foam is not dual to a triangulati…
Physical boundary Hilbert space and volume operator in the Lorentzian new spin-foam theory
You Ding, Carlo Rovelli
A covariant spin-foam formulation of quantum gravity has been recently developed, characterized by a kinematics which appears to match well the one of canonical loop quantum gravit…
