Ultraviolet Fixed Point in Covariant Loop Quantum Gravity
Muxin Han
We investigate the ultraviolet behavior of 4-dimensional Lorentzian covariant Loop Quantum Gravity (LQG) and address the problem of infinite ambiguities relating to the triangulati…
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…
