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…
Some properties of a new class of plane symmetric solution
Hongsheng Zhang, Hyerim Noh
A new class of static plane symmetric solution of Einstein field equation, which is judged as the source of Taub solution, was presented in our previous work. In this letter the pr…
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…
