Three dimensional loop quantum gravity: physical scalar product and spin foam models
In this paper, we address the problem of the dynamics in three dimensional loop quantum gravity with zero cosmological constant. We construct a rigorous definition of Rovelli’s generalized projection operator from the kinematical Hilbert space—corresponding to the quantization of the infinite dimensional kinematical configuration space of the theory—to the physical Hilbert space. In particular,...
متن کاملSpin Foam Models
While the use of spin networks has greatly improved our understanding of the kinematical aspects of quantum gravity, the dynamical aspects remain obscure. To address this problem, we deene the concept of a `spin foam' going from one spin network to another. Just as a spin network is a graph with edges labeled by representations and vertices labeled by intertwining operators, a spin foam is a 2-...
متن کاملCausality in Spin Foam Models
We compute Teitelboim’s causal propagator in the context of canonical loop quantum gravity. For the Lorentzian signature, we find that the resultant power series can be expressed as a sum over branched, colored two-surfaces with an intrinsic causal structure. This leads us to define a general structure which we call a “causal spin foam”. We also demonstrate that the causal evolution models for ...
متن کاملSpin Foam Models for Quantum Gravity
In this article we review the present status of the spin foam formulation of nonperturbative (background independent) quantum gravity. The article is divided in two parts. In the first part we present a general introduction to the main ideas emphasizing their motivation from various perspectives. Riemannian 3-dimensional gravity is used as a simple example to illustrate conceptual issues and ma...
متن کاملSpin Foam Models of String Theory
We review briefly the spin foam formalism for constructing path integrals for the BF and related theories. Then we describe how the path integral for the string theory on a group manifold can be defined as a two-dimensional spin foam state sum.
