Scalar fields around a rotating loop quantum gravity black hole: waveform, quasi-normal modes and superradiance [PDF]
Classical and quantum gravity, 2023 The rotating loop quantum gravity black hole is a newly proposed non-singular black hole, which eliminates spacetime singularities when a regularization parameter is introduced through loop quantum corrections.

Towards a quantum notion of covariance in spherically symmetric loop quantum gravity [PDF]
Physical Review D, 2022 The covariance of loop quantum gravity studies of spherically symmetric space-times has recently been questioned. This is a reasonable worry, given that they are formulated in terms of slicing-dependent variables.

Choice of connection in loop quantum gravity [PDF]
Physical Review D, 2001 We investigate the quantum area operator in the loop approach based on the Lorentz covariant hamiltonian formulation of general relativity. We show that there exists a two-parameter family of Lorentz connections giving rise to Wilson lines which are eigenstates of the area operator. For each connection the area spectrum is evaluated. In particular, the

Particles in Loop Quantum Gravity formalism: a thermodynamical description [PDF]
, 2022 In this work, we analyse the thermodynamical behavior of massive and massless particles within Loop Quantum Gravity formalism. We investigate a modified dispersion relation which suffices to derive all our results of interest in an \textit{analytical ...

Gravitational lensing by a black hole in effective loop quantum gravity [PDF]
Physical Review D, 2021 It is well known that general relativity is an effective theory of gravity at low energy scale, and actually quantum effects cannot be ignored in the strong-field regime.

Black hole collapse and bounce in effective loop quantum gravity [PDF]
Classical and quantum gravity, 2020 We derive effective equations with loop quantum gravity corrections for the Lemaître–Tolman–Bondi family of space-times, and use these to study quantum gravity effects in the Oppenheimer–Snyder collapse model.

On gonihedric loops and quantum gravity [PDF]
Journal of Physics A: Mathematical and General, 2006 We present an analysis of the gonihedric loop model, a reformulation of the two dimensional gonihedric spin model, using two different techniques. First, the usual regular lattice statistical physics problem is mapped onto a height model and studied analytically.

Spherically symmetric loop quantum gravity: analysis of improved dynamics [PDF]
Classical and quantum gravity, 2020 We study the ‘improved dynamics’ for the treatment of spherically symmetric space-times in loop quantum gravity introduced by Chiou et al in analogy with the one that has been constructed by Ashtekar, Pawlowski and Singh for the homogeneous space-times ...

A consistent model of non-singular Schwarzschild black hole in loop quantum gravity and its quasinormal modes [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We investigate the interior structure, perturbations, and the associated quasinormal modes of a quantum black hole model recently proposed by Bodendorfer, Mele, and Münch (BMM).

International Journal of Modern Physics D, 2014 This paper presents an "in-a-nutshell" yet self-contained introductory review on loop quantum gravity (LQG) — a background-independent, nonperturbative approach to a consistent quantum theory of gravity. Instead of rigorous and systematic derivations, it aims to provide a general picture of LQG, placing emphasis on the fundamental ideas and their ...
