Loop quantum cosmology with higher order holonomy corrections
Dah-Wei Chiou, Li-Fang Li
With a well-motivated extension of higher order holonomy corrections, the quantum theory of loop quantum cosmology (LQC) for the Friedmann-Robertson-Walker model (with a free…
On Newman-Penrose constants of stationary electrovacuum spacetimes
Xiangdong Zhang, Xiaoning Wu, Sijie Gao
A theorem related to the Newman-Penrose constants is proven. The theorem states that all the Newman-Penrose constants of asymptotically flat, stationary, asymptotically algebraical…
How loopy is the quantum bounce? A heuristic analysis of higher order holonomy corrections in LQC
Dah-Wei Chiou, Li-Fang Li
A well-motivated extension of higher order holonomy corrections in loop quantum cosmology (LQC) for the Friedmann-Robertson-Walker model is investigated at the level of heuri…
Proof of the entropy bound on dynamical horizons
Sijie Gao, Xiaoning Wu
The entropy bound conjecture concerning black hole dynamical horizons is proved. The conjecture states, if a dynamical horizon, , is bounded by two surfaces with areas of $A_B…
The black hole dynamical horizon and generalized second law of thermodynamics
Song He, Hongbao Zhang
The generalized second law of thermodynamics for a system containing a black hole dynamical horizon is proposed in a covariant way. Its validity is also tested in case of adiabatic…
Five-dimensional PPN formalism and experimental test of Kaluza-Klein theory
Peng Xu, Yongge Ma
The parametrized post Newtonian formalism for 5-dimensional metric theories with a compact extra dimension is developed. The relation of the 5-dimensional and 4-dimensional formula…
