Spin network Entanglement and Bulk-Boundary Map in Loop Quantum Gravity
Qian Chen
This thesis is dedicated to the study of open spin networks. We formulate quasi-local descriptions of loop quantum gravity. We investigate the coarse-graining procedure via tracing…
Intertwiner Entanglement Excitation and Holonomy Operator
Qian Chen, Etera R. Livine
In the loop quantum gravity framework, spin network states carry entanglement between quantum excitations of the geometry at different space points. This intertwiner entanglement i…
Loop Quantum Gravity's Boundary Maps
Qian Chen, Etera R. Livine
In canonical quantum gravity, the presence of spatial boundaries naturally leads to a boundary quantum states, representing quantum boundary conditions for the bulk fields. As a co…
Hamiltonian structure and connection-dynamics of Weyl gravity
Qian Chen, Yongge Ma
A crucial property of Weyl gravity is its conformal invariance. It is shown how this gauge symmetry is exactly reflected by the two constraints in the Hamiltonian framework. Since…
The Analysis to Quasi-Local Energy and Hamiltonian Constraint based on Variation
Qian Chen
In this paper, by arising condition in variation, from equal time to non-equal time, I reconsider how geometrodynamics equations allow to be derived from variational principle in g…
