Fermions in Loop Quantum Gravity and Resolution of Doubling Problem
Cong Zhang, Hongguang Liu, Muxin Han
The fermion propagator is derived in detail from the model of fermion coupled to loop quantum gravity. As an ingredient of the propagator, the vacuum state is defined as the ground…
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…
Shadow and stability of quantum-corrected black holes
Jinsong Yang, Cong Zhang, Yongge Ma
Recently the quantum Oppenheimer-Snyder gravitational collapse model has been proposed in loop quantum gravity, providing quantum-corrected Schwarzschild spacetimes as the exterior…
Quantum Oppenheimer-Snyder and Swiss Cheese models
Jerzy Lewandowski, Yongge Ma, Jinsong Yang +1
By considering the quantum Oppenheimer-Snyder model in loop quantum cosmology, a new quantum black hole model whose metric tensor is a suitably deformed Schwarzschild one is derive…
Fermions on Quantum Geometry and Resolution of Doubling Problem
Cong Zhang, Hongguang Liu, Muxin Han
The fermion doubling problem has an important impact on quantum gravity, by revealing the tension between fermion and the fundamental discreteness of quantum spacetime. In this wor…
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…
