New tools for Loop Quantum Gravity with applications to a simple model [PDF]
, 2012 Loop Quantum Gravity is now a well established approach to quantum gravity. One of the main challenges still faced by the theory is constructing a consistent dynamics which would lead back to the standard dynamics of the gravitational field at large ...

Effective line elements and black-hole models in canonical loop quantum gravity [PDF]
Physical Review D, 2018 Canonical quantization is often used to suggest new effects in quantum gravity, in the dynamics as well as the structure of space-time. Usually, possible phenomena are first seen in a modified version of the classical dynamics, for instance in an ...

Higher dimensional Loop Quantum Cosmology [PDF]
, 2015 Loop quantum cosmology(LQC) is the symmetric model of loop quantum gravity. In this paper, we generalize the structure of loop quantum cosmology to the theories with arbitrary spacetime dimensions.

Loop Representation of Quantum Gravity
Annales Henri Poincaré, 2023 A hyperlink is a finite set of non-intersecting simple closed curves in $\mathbb{R}^4 \equiv \mathbb{R} \times \mathbb{R}^3$, each curve is either a matter or geometric loop. We consider an equivalence class of such hyperlinks, up to time-like isotopy, preserving time-ordering.

Loop-Quantum-Gravity Vertex Amplitude [PDF]
Physical Review Letters, 2007 Spinfoam theories are hoped to provide the dynamics of non-perturbative loop quantum gravity. But a number of their features remain elusive. The best studied one -the euclidean Barrett-Crane model- does not have the boundary state space needed for this, and there are recent indications that, consequently, it may fail to yield the correct low-energy $n$-

Primordial Fluctuations From Quantum Gravity
Frontiers in Astronomy and Space Sciences, 2021 We study the fluctuations and the correlations between spatial regions generated in the primordial quantum gravitational era of the universe. We point out that these can be computed using the Lorentzian dynamics defined by the Loop Quantum Gravity ...

1/N correction in holographic Wilson loop from quantum gravity
Journal of High Energy Physics, 2019 We study 1/N corrections to a Wilson loop in holographic duality. Extending the AdS/CFT correspondence beyond the large N limit is an important but a subtle issue, as it needs quantum gravity corrections in the gravity side.

Effective dynamics from coherent state path integral of full loop quantum gravity [PDF]
Physical Review D, 2019 A new routine is proposed to relate loop quantum cosmology (LQC) to loop quantum gravity (LQG) from the perspective of effective dynamics. We derive the big-bang singularity resolution and big bounce from the first principle of full canonical LQG.
