Emergence of string-like physics from Lorentz invariance in loop quantum gravity [PDF]
, 2014 We consider a quantum field theory on a spherically symmetric quantum space time described by loop quantum gravity. The spin network description of space time in such a theory leads to equations for the quantum field that are discrete.

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.

Perspectives on the dynamics in a loop quantum gravity effective description of black hole interiors [PDF]
Physical Review D, 2019 In the loop quantum gravity context, there have been numerous proposals to quantize the reduced phase space of a black hole, and develop a classical effective description for its interior which eventually resolves the singularity.

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.

Shadow and stability of quantum-corrected black holes
European Physical Journal C: Particles and Fields, 2023 Recently the quantum Oppenheimer–Snyder gravitational collapse model has been proposed in loop quantum gravity, providing quantum-corrected Schwarzschild spacetimes as the exterior of the collapsing dust ball.

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 ...

Towards Cosmological Dynamics from Loop Quantum Gravity [PDF]
, 2018 We present a systematic study of the cosmological dynamics resulting from an effective Hamiltonian, recently derived in loop quantum gravity (LQG) using Thiemann's regularization and earlier obtained in loop quantum cosmology (LQC) by keeping the ...
