Spinfoams and high performance computing
Pietro Dona, Muxin Han, Hongguang Liu
Numerical methods are a powerful tool for doing calculations in spinfoam theory. We review the major frameworks available, their definition, and various applications. We start from…
Covariant -scheme effective dynamics, mimetic gravity, and non-singular black holes: Applications to spherical symmetric quantum gravity and CGHS model
Muxin Han, Hongguang Liu
We propose a new -scheme Hamiltonian effective dynamics in the spherical symmetric sector of Loop Quantum Gravity (LQG). The effective dynamics is generally covariant as der…
Spherical symmetric gravitational collapse of a dust cloud: polymerized dynamics in reduced phase space
Kristina Giesel, Muxin Han, Bao-Fei Li +2
Based on the effective dynamics in the scheme of the spherical symmetry reduced model in the reduced phase space formulation of loop quantum gravity (LQG), we investigate…
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…
Experimental Simulation of Loop Quantum Gravity on a Photonic Chip
Reinier van der Meer, Zichang Huang, Malaquias Correa Anguita +6
The unification of general relativity and quantum theory is one of the fascinating problems of modern physics. One leading solution is Loop Quantum Gravity (LQG). Simulating LQG ma…
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…
