On the summation and triangulation independence of Lorentzian spinfoam amplitudes for all LQG
Muxin Han
This paper investigates the fundamental issue of triangulation dependence in spinfoam quantum gravity. It introduces a novel framework, named spinfoam stack, to systematically sum…

Lorentzian spinfoam gravity path integral and geometrical area-law entanglement entropy
Muxin Han
This paper investigates entanglement entropy in 3+1 dimensional Lorentzian covariant Loop Quantum Gravity (LQG). We compute the entanglement entropy for a spatial region from state…

Entanglement entropy in Loop Quantum Gravity and geometrical area law
Muxin Han
The non-factorizing nature of the Hilbert space in Loop Quantum Gravity (LQG) due to gauge invariance requires a generalized definition of entanglement entropy. This work employs t…
