We show that if the flat‐spacetime wavefunction in the spin network basis of Loop Quantum Gravity has a large‐spin asymptotics given by a Gaussian function, then the corresponding graviton propagator has the correct large‐distance asymptotics nonperturbatively in the equal‐time limit. 

Large-spin asymptotics of Euclidean LQG flat-space wavefunctions

We analyze the large-spin asymptotics of a class of spin-network wavefunctions of Euclidean Loop Quantum Gravity, which corresponds to a flat spacetime. A wavefunction from this class can be

Fermion spins in loop quantum gravity

We define and study kinematical observables involving fermion spin, such as the total spin of a collection of particles, in loop quantum gravity. Due to the requirement of gauge invariance, the

Effective action and semi-classical limit of spin-foam models

We define an effective action for spin-foam models of quantum gravity by adapting the background field method from quantum field theory. We show that the Regge action is the leading term in the



Graviton propagator from background-independent quantum gravity.

A component of the propagator is computed to first order, under some approximations, obtaining the correct large-distance behavior, indicating a way for deriving conventional spacetime quantities from a background-independent theory.

Flat spacetime vacuum in loop quantum gravity

We propose a state in loop quantum gravity theory with zero cosmological constant such that it could be associated with the flat spacetime vacuum solution. This state is constructed by defining the

Quantum gravity vacuum and invariants of embedded spin networks

We show that the path integral for the three-dimensional SU (2) BF theory with a Wilson loop or a spin network function inserted can be understood as the Rovelli-Smolin loop transform of a

Relativistic spin networks and quantum gravity

Relativistic spin networks are defined by considering the spin covering of the group SO(4), SU(2)×SU(2). Relativistic quantum spins are related to the geometry of the two-dimensional faces of a

Quantum field theory of spin networks

We study the transition amplitudes in the state-sum models of quantum gravity in D = 2-4 spacetime dimensions by using the field theory over the GD formulation, where G is the relevant Lie group. By

Invariants of Spin Networks Embedded in Three-Manifolds

We study the invariants of spin networks embedded in a three-dimensional manifold which are based on the path integral for SU(2) BF-Theory. These invariants appear naturally in Loop Quantum Gravity,
