AN INTRODUCTION TO QUANTUM GRAVITY [PDF]
International Journal of Geometric Methods in Modern Physics, 2008 After an overview of the physical motivations for studying quantum gravity, we reprint THE FORMAL STRUCTURE OF QUANTUM GRAVITY, i.e. the 1978 Cargèse Lectures in Levy & Deser (1979): Recent Developments in Gravitation pp. 275–322 by Professor B. S. DeWitt, with kind permission of Springer Science and Business Media.

Clocks and rods in Jackiw-Teitelboim quantum gravity [PDF]
Journal of High Energy Physics, 2019 We specify bulk coordinates in Jackiw-Teitelboim (JT) gravity using a boundary-intrinsic radar definition. This allows us to study and calculate exactly diff-invariant bulk correlation functions of matter-coupled JT gravity, which are found to satisfy ...

Gravity entanglement, quantum reference systems, degrees of freedom [PDF]
Classical and quantum gravity, 2022 Gravity mediated entanglement (GME) has been proposed as the first experimentally testable signature of quantum gravity. However, to what extent the effect is due to quantum gravity is under debate.

Quantum gravity at the fifth root of unity
Physics Open, 2022 We consider quantum transition amplitudes, partition functions and observables for 3D spin foam models within SU(2)quantum group deformation symmetry, where the deformation parameter is postulated to be a complex fifth root of unity.

Group Theory of Syntactical Freedom in DNA Transcription and Genome Decoding
Current Issues in Molecular Biology, 2022 Transcription factors (TFs) are proteins that recognize specific DNA fragments in order to decode the genome and ensure its optimal functioning. TFs work at the local and global scales by specifying cell type, cell growth and death, cell migration ...

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 ...

Quantum sensing for gravity cartography
Nature, 2022 The sensing of gravity has emerged as a tool in geophysics applications such as engineering and climate research1–3, including the monitoring of temporal variations in aquifers4 and geodesy5.

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.

Quantum Gravity: A Fluctuating Point of View [PDF]
Frontiers of Physics, 2020 In this contribution, we discuss the asymptotic safety scenario for quantum gravity with a functional renormalization group approach that disentangles dynamical metric fluctuations from the background metric.
