Quaternion-Loop Quantum Gravity [PDF]
Foundations of Physics, 2009 It is shown that the Riemannian curvature of the 3-dimensional hypersurfaces in space-time, described by the Wilson loop integral, can be represented by a quaternion quantum operator induced by the SU(2) gauge potential, thus providing a justification for quaternion quantum gravity at the Tev energy scale.

Loop Quantum Cosmology, Modified Gravity and Extra Dimensions
Universe, 2016 Loop quantum cosmology (LQC) is a framework of quantum cosmology based on the quantization of symmetry reduced models following the quantization techniques of loop quantum gravity (LQG).

European Physical Journal C: Particles and Fields, 2021 In this work, we investigate the quasinormal modes for a massive scalar field with a nonminimal coupling with gravity in the spacetime of a loop quantum black hole, known as the self-dual black hole.

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 ...

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.

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 ...

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.

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.
