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…
Alternative loop quantum cosmology
Jinsong Yang, Cong Zhang, Xiangdong Zhang
An alternative quantization of the gravitational Hamiltonian constraint of the Friedmann-Robertson-Walker model is proposed by treating the Euclidean term and the Lorentzian…
Realization of Dirac quantization in loop quantum gravity
Xiangdong Zhang, Yongge Ma
The system of gravity coupled to the non-rotational dust field is studied at both classical and quantum levels. The scalar constraint of the system can be written in the form of a…
On the gauge reduction with respect to simplicity constraint in all dimensional loop quantum gravity
Gaoping Long, Xiangdong Zhang
In this paper, we are going to discuss the gauge reduction with respect to the simplicity constraint in both classical and quantum theory of all dimensional loop quantum gravity. W…
Efficient verification of arbitrary entangled states with homogeneous local measurements
Ye-Chao Liu, Yinfei Li, Jiangwei Shang +1
Quantum state verification (QSV) is the task of relying on local measurements only to verify that a given quantum device does produce the desired target state. Up to now, certain t…
The thermodynamics of isolated horizons in loop quantum gravity
Shupeng Song, Gaoping Long, Cong Zhang +1
The statistical mechanical calculation of the thermodynamical properties of non-rotating isolated horizons are studied in the loop quantum gravity framework. By employing the Hawki…
Tensor Perturbations and Thick Branes in Higher Dimensional Gauss-Bonnet Gravity
Yongqun Xu, Xiangdong Zhang
A thick brane model with Gauss-Bonnet action in a homogeneous anisotropic spacetime is studied. By choosing a concrete metric ansatz, we show that this spacetime is sta…
Solar system constraints of a polymer black hole in loop quantum gravity
Yun-Long Liu, Zhao-Qing Feng, Xiang-Dong Zhang
A new polymer black hole solution in loop quantum gravity was proposed recently. The difference between the polymer black hole and Schwarzschild black hole is captured by a quantum…
