Signatures of the quantization of gravity at gravitational wave detectors
Physical Review D, 2021 We develop a formalism to calculate the response of a model gravitational wave detector to a quantized gravitational field. Coupling a detector to a quantum field induces stochastic fluctuations (“noise”) in the length of the detector arm.

Quantization of Gravitationally Bound Systems
Universe, 2021 Some of the approaches to quantization in gravity theory concerning gravitationally bound systems are considered. Grades of quantization applicable to these systems have been classified in terms of quantum mechanics, quantum field theory, and quantum ...

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

Landau Levels in a Gravitational Field: The Schwarzschild Spacetime Case
Universe, 2021 We investigate the gravitational effect on Landau levels. We show that the familiar infinite Landau degeneracy of the energy levels of a quantum particle moving inside a uniform and constant magnetic field is removed by the interaction of the particle ...

On the Choice of Variable for Quantization of Conformal GR
UniverseThe 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.

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

Exact uncertainty principle and quantization: implications for the gravitational field
Brazilian Journal of Physics, 2005 The quantization of the gravitational field is discussed within the exact uncertainty approach. The method may be described as a Hamilton-Jacobi quantization of gravity. It differs from previous approaches that take the classical Hamilton-Jacobi equation

Hybrid Loop Quantum Cosmology: An Overview
Frontiers in Astronomy and Space Sciences, 2021 Loop Quantum Gravity is a nonperturbative and background independent program for the quantization of General Relativity. Its underlying formalism has been applied successfully to the study of cosmological spacetimes, both to test the principles and ...

Universe, 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
