Semiclassical Loop Quantum Gravity
"... Abstract. In this article we explore the origin of black hole thermodynamics using semi-classical states in loop quantum gravity. We re-examine the case of entropy using a density matrix for a coherent state and describe correlations across the horizon due to SU(2) in-tertwiners. We further show tha ..."

Matter in Loop Quantum Gravity
- SYMMETRY, INTEGRABILITY AND GEOMETRY: METHODS AND APPLICATIONS
, 2012
"... Loop quantum gravity, a non-perturbative and manifestly background free, quantum theory of gravity implies that at the kinematical level the spatial geometry is discrete in a specific sense. The spirit of background independence also requires a nonstandard quantum representation of matter. While loo ..."

Automorphisms in Loop Quantum Gravity
, 2008
"... We investigate a certain distributional extension of the group of spatial diffeomorphisms in Loop Quantum Gravity. This extension, which is given by the automorphisms Aut(P) of the path groupoid P, was proposed by Velhinho and is inspired by category theory. This group is much larger than the group ..."

Lattice Loop Quantum Gravity
"... We present a separable version of Loop Quantum Gravity (LQG) based on an inductive system of cubic lattices. We construct semi-classical states for which the LQG operators – the flux, the area and the volume operators – have the right classical limits. Also, we present the Hamilton and diffeomorphis ..."

The Proca-field in Loop Quantum Gravity
, 2006
"... Abstract. In this paper we investigate the Proca-field in the framework of Loop Quantum Gravity. It turns out that the methods developed there can be applied to the symplectically embedded Proca-field, giving a rigorous, consistent, non-perturbative quantization of the theory. This can be achieved b ..."

On loop states in loop quantum gravity
"... We explicitly construct and characterize all possible independent loop states in 3+1 dimensional loop quantum gravity by regulating it on a 3-d regular lattice in the Hamiltonian formalism. These loop states, characterized by the (dual) angular momentum quantum numbers, describe SU(2) rigid rotators ..."
