SYNCHRONOUS QUANTUM GRAVITY [PDF]
International Journal of Modern Physics A, 2008 The implications of restricting the covariance principle within a Gaussian gauge are developed both on a classical and a quantum level. Hence, we investigate the cosmological issues of the obtained Schrödinger Quantum Gravity with respect to the asymptotically early dynamics of a generic Universe.

On quantum gravity and quantum gravity phenomenology
The Sixteenth Marcel Grossmann Meeting, 2023 This article summarizes a new approach to quantum gravity based on the concepts of modular spacetime, Born geometry, and metastring theory and their applications to quantum gravity phenomenology. In particular, we discuss a new understanding of dark matter in terms of metaparticles (zero modes of the metastring) and its relation to dark energy (the ...

Quantum channels in quantum gravity [PDF]
International Journal of Modern Physics D, 2014 The black hole final state proposal implements manifest unitarity in the process of black hole formation and evaporation in quantum gravity, by postulating a unique final state boundary condition at the singularity. We argue that this proposal can be embedded in the gauge/gravity context by invoking a path integral formalism inspired by the Schwinger ...

Non-Local Game of Life in 2D Quasicrystals
Crystals, 2018 On a two-dimensional quasicrystal, a Penrose tiling, we simulate for the first time a game of life dynamics governed by non-local rules. Quasicrystals have inherently non-local order since any local patch, the emperor, forces the existence of a large ...

Mathematics, 2018 In geometrically frustrated clusters of polyhedra, gaps between faces can be closed without distorting the polyhedra by the long established method of discrete curvature, which consists of curving the space into a fourth dimension, resulting in a ...

Quantum Gravity phenomenology [PDF]
Physics World, 2003 9 pages, LaTex. These notes were prepared while working on an invited contribution to the November 2003 issue of Physics World, which focused on quantum gravity. They intend to give a non-technical introduction (accessible to readers from outside quantum gravity) to "Quantum Gravity Phenomenology"

Supersymmetric minisuperspace models in self-dual loop quantum cosmology
Journal of High Energy Physics, 2021 In this paper, we study a class of symmetry reduced models of N $$ \mathcal{N} $$ = 1 super- gravity using self-dual variables. It is based on a particular Ansatz for the gravitino field as proposed by D’Eath et al. We show that the essential part of the
