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…
Alternative quantization of the Hamiltonian in isotropic loop quantum cosmology
Jinsong Yang, You Ding, Yongge Ma
Since there are quantization ambiguities in constructing the Hamiltonian constraint operator in isotropic loop quantum cosmology, it is crucial to check whether the key features of…
Effective Scenario of Loop Quantum Cosmology
You Ding, Yongge Ma, Jinsong Yang
Semiclassical states in isotropic loop quantum cosmology are employed to show that the improved dynamics has the correct classical limit. The effective Hamiltonian for the quantum…
Hamiltonian analysis of -dimensional Palatini gravity with matter
Muxin Han, Yongge Ma, You Ding +1
We consider the Palatini formalism of gravity with cosmological constant coupled to a scalar field in -dimensions. The -dimensional Einstein equations with can be…
Palatini Formalism of 5-Dimensional Kaluza-Klein Theory
You Ding, Yongge Ma, Muxin Han +1
The Einstein field equations can be derived in dimensions () by the variations of the Palatini action. The Killing reduction of 5-dimensional Palatini action is studied on…
