چکیده

To clarify the geometric information encoded in $SO(D+1)$ spin-network states for higher dimensional loop quantum gravity, we generalize twisted-geometry parametrization of $SU(2)$ phase space ($1+3$)-dimensional gravity to that all-dimensional case. The Poisson structure terms twisted variables suggests a new gauge reduction procedure, with respect discretized gauss and simplicity constraints governing kinematics theory. Endowed meaning via parametrization, our procedure serves identify proper freedom associated anomalous subsequently leads desired classical state (twisted) discrete Arnowitt-Deser-Misner data.

Separable Hilbert space in Loop Quantum Gravity

We study the separability of the state space of loop quantum gravity. In the standard construction, the kinematical Hilbert space of the diffeomorphism-invariant states is nonseparable. This is a consequence of the fact that the knot-space of the equivalence classes of graphs under diffeomorphisms is noncountable. However, the continuous moduli labeling these classes do not appear to affect the...

Three Dimensional Loop Quantum Gravity: Particles and the Quantum Double

It is well known that the quantum double structure plays an important role in three dimensional quantum gravity coupled to matter field. In this paper, we show how this algebraic structure emerges in the context of three dimensional Riemannian loop quantum gravity (LQG) coupled to a finite number of massive spinless point particles. In LQG, physical states are usually constructed from the notio...

Geometric Structures and Loop Variables in (2+1)-Dimensional Gravity

Ashtekar’s connection representation for general relativity [1, 2] and the closely related loop variable approach [3] have generated a good deal of excitement over the past few years. While it is too early to make firm predictions, there seems to be some real hope that these new variables will allow the construction of a consistent nonperturbative quantum theory of gravity. Some important progr...

Hilbert space structure of covariant loop quantum gravity

We investigate the Hilbert space in the Lorentz covariant approach to loop quantum gravity. We restrict ourselves to the space where all area operators are simultaneously diagonalizable, assuming that it exists. In this sector quantum states are realized by a generalization of spin network states based on Lorentz Wilson lines projected on irreducible representations of an SO(3) subgroup. The pr...

Phase-space and Black Hole Entropy of Toroidal Horizons in Loop Quantum Gravity

In the context of loop quantum gravity, we construct the phase-space of the isolated horizon with toroidal topology. Within the loop quantum gravity framework, this horizon is described by a torus with N punctures and the dimension of the corresponding phase-space is calculated including the toroidal cycles as degrees of freedom. From this, the black hole entropy can be calculated by counting t...
