Quantum induced shock dynamics in gravitational collapse: insights from effective models and numerical frameworks
Hongguang Liu, Dongxue Qu
We explore the formation and evolution of shock waves in spherically symmetric gravitational collapse within a Loop Quantum Gravity (LQG) inspired effective framework. In this sett…

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…
