The space of states and operators for a large class of background independent theories of quantum spacetime dynamics is defined. The SU(2) spin networks of quantum general relativity are replaced by labelled compact two-dimensional surfaces. The space of states of the theory is the direct sum of the spaces of invariant tensors of a quantum group ${G}_{q}$ over all compact (finite genus) oriented 2-surfaces. The dynamics is background independent and locally causal. The dynamics constructs…

Quantum gravity and the standard model

We show that a class of background-independent models of quantum spacetime have local excitations that can be mapped to the first-generation fermions of the standard model of particle physics. These

Observables in quantum gravity

We study a family of physical observable quantities in quantum gravity. We denote them W functions, or n-net functions. They represent transition amplitudes between quantum states of the geometry,

Spacetime geometry from algebra: spin foam models for non-perturbative quantum gravity

This is an introduction to spin foam models for non-perturbative quantum gravity, an approach that lies at the point of convergence of many different research areas, including loop quantum gravity,

Higher-Dimensional Algebra and Planck-Scale Physics

This is a nontechnical introduction to recent work on quantum gravity using ideas from higher-dimensional algebra. We argue that reconciling general relativity with the Standard Model requires a

Holography, Quantum Geometry, and Quantum Information Theory

The Holographic Conjecture is interpreted in terms of quantum bits (qubits) and the model is analysed in the framework of the theory of presheaves (varying sets on a causal set) and a quantum history is obtained.

Quantum spin dynamics (QSD): VII. Symplectic structures and continuum lattice formulations of gauge field theories

Interesting nonlinear functions on the phase spaces of classical field theories can never be quantized immediately because the basic fields of the theory become operator-valued distributions.

Free vacuum for loop quantum gravity

We linearize extended ADM gravity around the flat torus, and use the associated Fock vacuum to construct a state that could play the role of a ‘free’ vacuum in loop quantum gravity. The state we

Introduction to loop quantum gravity and spin foams

These notes are a didactic overview of the non perturbative and background independent approach to a quantum theory of gravity known as loop quantum gravity. The definition of real connection

Gauge field theory coherent states (GCS): I. General properties

In this paper we outline a rather general construction of diffeomorphism covariant coherent states for quantum gauge theories. By this we mean states ψ(A,E), labelled by a point (A,E) in the

A new basis on the state space of non-perturbative quantum gravity is introduced that allows a simple expression for the exact solutions of the Hamiltonian constraint (Wheeler-DeWitt equation) that have been discovered in the loop representation.

A quantum Hamiltonian which evolves the gravitational field according to time as measured by constant surfaces of a scalar field is defined through a regularization procedure based on the loop

Linking topological quantum field theory and nonperturbative quantum gravity

Quantum gravity is studied nonperturbatively in the case in which space has a boundary with finite area. A natural set of boundary conditions is studied in the Euclidean signature theory in which the

We construct an operator that measures the length of a curve in four-dimensional Lorentzian vacuum quantum gravity. We work in a representation in which an SU(2) connection is diagonal and it is

'Sum over surfaces' form of loop quantum gravity

We derive a spacetime formulation of quantum general relativity from (hamiltonian) loop quantum gravity. In particular, we study the quantum propagator that evolves the 3-geometry in proper time. We
