Quantum Geometry Effects in Quantum Field Theory: Hamiltonian constraint Generates Gravity-Matter Entanglement
Gaoping Long, Cong Zhang
In this paper, we address a foundational challenge in quantum field theory on curved spacetime by developing a consistent framework within loop quantum gravity. We introduce a meth…

Expansion operators in spherically symmetric loop quantum gravity
Xiaotian Fei, Gaoping Long, Yongge Ma +1
The ingoing and outgoing null expansions associated to a spatial 2-sphere are quantized in the spherically symmetric model of loop quantum gravity. It is shown that the resulting e…
