Signatures of the quantum nature of gravity in the differential motion of two masses [PDF]
Quantum Science and Technology, 2021 We show that a signature of the quantum nature of gravity is the quantum mechanical squeezing of the differential motion of two identical masses with respect to their common mode.

Differential Geometrical Formulation of Gauge Theory of Gravity [PDF]
, 2002 Differential geometric formulation of quantum gauge theory of gravity is studied in this paper. The quantum gauge theory of gravity which is proposed in the references hep-th/0109145 and hep-th/0112062 is formulated completely in the framework of ...

Periodic Modification of the Boerdijk–Coxeter Helix (tetrahelix)
Mathematics, 2019 The Boerdijk−Coxeter helix is a helical structure of tetrahedra which possesses no non-trivial translational or rotational symmetries. In this document, we develop a procedure by which this structure is modified to obtain both translational and ...

Spin Entanglement Witness for Quantum Gravity. [PDF]
Physical Review Letters, 2017 Understanding gravity in the framework of quantum mechanics is one of the great challenges in modern physics. However, the lack of empirical evidence has lead to a debate on whether gravity is a quantum entity.

New Journal of Physics, 2005 The goal of this article is to present a broad perspective on quantum gravity for \emph{non-experts}. After a historical introduction, key physical problems of quantum gravity are illustrated. While there are a number of interesting and insightful approaches to address these issues, over the past two decades sustained progress has primarily occurred in

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 ...

Dilaton Gravity with a Non-minmally Coupled Scalar Field [PDF]
, 2000 We discuss the two-dimensional dilaton gravity with a scalar field as the source matter. The coupling between the gravity and the scalar, massless, field is presented in an unusual form.

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 ...

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
