Loop Quantum Gravity and Observations [PDF]

open access: yes, 2017
Quantum gravity has long been thought to be completely decoupled from experiments or observations. Although it is true that smoking guns are still missing, there are now serious hopes that quantum gravity phenomena might be tested. We review here some possible ways to observe loop quantum gravity effects either in the framework of cosmology or in ...

Relativistic Planck-scale polymer

open access: yesPhysics Letters B, 2017
Polymer quantum mechanics has been studied as a simplified picture that reflects some of the key properties of Loop Quantum Gravity; however, while the fate of relativistic symmetries in Loop Quantum Gravity is still not established, it is usually ...

Quasinormal modes of a massive scalar field nonminimally coupled to gravity in the spacetime of self-dual black hole

open access: yesEuropean 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.

FUNDAMENTAL STRUCTURE OF LOOP QUANTUM GRAVITY [PDF]

open access: yesInternational Journal of Modern Physics D, 2007
In the recent twenty years, loop quantum gravity, a background independent approach to unify general relativity and quantum mechanics, has been widely investigated. The aim of loop quantum gravity is to construct a mathematically rigorous, background independent, non-perturbative quantum theory for a Lorentzian gravitational field on a four ...

Primordial Fluctuations From Quantum Gravity

open access: yesFrontiers 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

open access: yesJournal 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.
