The Curled Up Dimension in Quasicrystals
Crystals, 2021 Most quasicrystals can be generated by the cut-and-project method from higher dimensional parent lattices. In doing so they lose the periodic order their parent lattice possess, replaced with aperiodic order, due to the irrationality of the projection ...

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 ...

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 ...

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 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.

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.

Finite Groups for the Kummer Surface: The Genetic Code and a Quantum Gravity Analogy
Quantum Reports, 2021 The Kummer surface was constructed in 1864. It corresponds to the desingularization of the quotient of a 4-torus by 16 complex double points. Kummer surface is known to play a role in some models of quantum gravity.

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.

Graph Coverings for Investigating Non Local Structures in Proteins, Music and Poems
Sci, 2021 We explore the structural similarities in three different languages, first in the protein language whose primary letters are the amino acids, second in the musical language whose primary letters are the notes, and third in the poetry language whose ...

An experiment for observing quantum gravity phenomena using twin table-top 3D interferometers [PDF]
Classical and quantum gravity, 2020 Theories of quantum gravity based on the holographic principle predict the existence of quantum fluctuations of distance measurements that accumulate and exhibit correlations over macroscopic distances.
