The one-loop effective action from the coherent state path integral of loop quantum gravity
Renata Ferrero, Muxin Han, Hongguang Liu
We adopt a novel approach to combine path integral methods with Loop Quantum Gravity (LQG). Our approach builds upon the recently developed coherent state path integral formulation…

Properties of 4D spinfoam quantum geometry: Results from next-to-leading order spinfoam large- asymptotics of 1-5 Pachner move
Haida Li, Muxin Han, Hongguang Liu +2
This paper proposes several criteria to probe the non-trivialities of 4-dimensional geometry that impact spinfoam amplitude. These criteria include the standard deviation of 4-volu…
