Squeezed vacua in loop quantum gravity [PDF]
arXiv, 2016 We introduce squeezed vacua in loop quantum gravity, a new overcomplete basis of states that contain prescribable correlations between geometric operators. We study the behavior of long-range correlations and discuss the relevance of these states for the reconstruction of a semiclassical spacetime from loop quantum gravity.

Gravitational Wilson Loop and Large Scale Curvature
, 2007 In a quantum theory of gravity the gravitational Wilson loop, defined as a suitable quantum average of a parallel transport operator around a large near-planar loop, provides important information about the large-scale curvature properties of the ...

Bounce Loop Quantum Cosmology Corrected Gauss-Bonnet Gravity
, 2015 We develop a Gauss-Bonnet extension of Loop Quantum Cosmology, by introducing holonomy corrections in modified $F(\mathcal{G})$ theories of gravity.

Intersecting Quantum Gravity with Noncommutative Geometry - a Review
Symmetry, Integrability and Geometry: Methods and Applications, 2012 We review applications of noncommutative geometry in canonical quantum gravity. First, we show that the framework of loop quantum gravity includes natural noncommutative structures which have, hitherto, not been explored.

Loops, Loop Sequences and Loop Surfaces in Statistical Geodesics, and Quantum Information [PDF]
arXiv, 2010 The locus of probability flow in Quantum Mechanics and information is explored. We explore loops, loop sequences and loop surfaces in the statistical geodesics. Having known about the loop character of the statistical geodesics in probability space, we discuss wider physical aspects of consequences of the geometry of the probabilities in the form of ...

Quantum phenomenological gravitational dynamics: a general view from thermodynamics of spacetime
Journal of High Energy Physics, 2020 In this work we derive general quantum phenomenological equations of gravitational dynamics and analyse its features. The derivation uses the formalism developed in thermodynamics of spacetime and introduces low energy quantum gravity modifications to it.

Loop-deformed Poincar\'e algebra
, 2013 In this essay we present evidence suggesting that loop quantum gravity leads to deformation of the local Poincar\'e algebra within the limit of high energies.

Groups of flux-like transformations in loop quantum gravity [PDF]
arXiv, 2009 We present a group of transformations in the quantum configuration space of loop quantum gravity that contains the set of all transformations generated by the flux variables.

Lessons from Toy-Models for the Dynamics of Loop Quantum Gravity
Symmetry, Integrability and Geometry: Methods and Applications, 2012 We review some approaches to the Hamiltonian dynamics of (loop) quantum gravity, the main issues being the regularization of the Hamiltonian and the continuum limit.
