On the Choice of Variable for Quantization of Conformal GR [PDF]

open access: yesUniverse
The possibility of using spin connection components as basic quantization variables of a conformal version of general relativity is studied. The considered model contains gravitational degrees of freedom and a scalar dilaton field.

Discreteness of space from GUP in a weak gravitational field [PDF]

open access: yesPhysics Letters B, 2016
Quantum gravity effects modify the Heisenberg's uncertainty principle to a generalized uncertainty principle (GUP). Earlier work showed that the GUP-induced corrections to the Schrödinger equation, when applied to a non-relativistic particle in a one ...

On the quantum field theory of the gravitational interactions [PDF]

open access: yesJournal of High Energy Physics, 2017
We study the main options for a unitary and renormalizable, local quantum field theory of the gravitational interactions. The first model is a Lee-Wick superrenormalizable higher-derivative gravity, formulated as a nonanalytically Wick rotated Euclidean ...

Testing the Wave-Particle Duality of Gravitational Wave Using the Spin-Orbital-Hall Effect of Structured Light

open access: yesUniverse, 2022
Probing the polarization of gravitational waves (GWs) would provide evidence of graviton, indicating the quantization of gravity. Motivated by the next generation of gravitational wave detectors, we make an attempt to study the possible helicity coupling

Some features of an interaction of electromagnetic radiation quantums with a gravitational field and a problem of graviton

open access: yesВестник Самарского государственного технического университета. Серия: Технические науки, 2020
The problems connected to propagation of a gravitational field are considered. The law of electromagnetic radiation frequency change in gravitational field is shown. The problem of a gravitational field quantization is investigated.

Quantization of the Gravitational Field in the Expanding Universe [PDF]

open access: yesProgress of Theoretical Physics, 1963
An attempt is made to quantize, in the linear approximation, the gravitational field in the expanding universe, from the standpoint of canonical formalism. By using a transformation function and decomposing suitably the field operator into positive and negative frequency parts, explicit forms of the four- dimensional commutation function and the ...

Quantum correlations beyond entanglement in a classical-channel model of gravity

open access: yesScientific Reports, 2022
A direct quantization of the Newtonian interaction between two masses is known to establish entanglement, which if detected would witness the quantum nature of the gravitational field.

Graviton detection and the quantization of gravity [PDF]

open access: yes, 2023
We revisit a question asked by Dyson: Is a graviton detectable? We demonstrate that in both Dyson\u27s original sense and in a more modern measurement-theoretic sense, it is possible to construct a detector sensitive to single gravitons, and in fact a ...

Quantization and variational problem of the Gubser-Rocha Einstein-Maxwell-Dilaton model, conformal and non-conformal deformations, and its proper thermodynamics

open access: yesJournal of High Energy Physics, 2023
We show that the strongly coupled field theory holographically dual to the Gubser-Rocha anti-de-Sitter Einstein-Maxwell-Dilaton theory describes not a single non-trivial AdS2 IR fixed point, but a one-parameter family.

Gravitational Dynamics—A Novel Shift in the Hamiltonian Paradigm

open access: yesUniverse, 2021
It is well known that Einstein’s equations assume a simple polynomial form in the Hamiltonian framework based on a Yang-Mills phase space. We re-examine the gravitational dynamics in this framework and show that time evolution of the gravitational field ...
