Probing mass inflation in polymerized vacuum regular black holes via colliding null shells
Hongguang Liu, Ioannis Soranidis
We derive a class of inner-extremal regular black hole solutions characterized by a degenerate inner horizon. These geometries arise as polymerized vacuum configurations inspired b…
Asymptotic Symmetries of the Holst Action at Spatial Infinity: Including Supertranslations
Sepideh Bakhoda, Hongguang Liu
We investigate the asymptotic symmetries of General Relativity at spatial infinity within the first-order formalism described by the Holst action. Employing the covariant phase spa…
Bridging Quantum and Semiclassical Volume: A Numerical Study of Coherent State Matrix Elements in Loop Quantum Gravity
Haida Li, Hongguang Liu
In Loop Quantum Gravity, the quantum action of the volume operator is crucial in understanding quantum dynamics. In this work, we implement a generalized numerical algorithm that c…
Beyond Expectation Values: Generalized Semiclassical Expansions for Matrix Elements of Gauge Coherent States
Haida Li, Hongguang Liu
We derive an asymptotic expansion for off-diagonal coherent-state matrix elements of non-polynomial operators in gauge theories admitting holomorphic coherent-state representations…
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…
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…
