Stochastic quantization of the linearized gravitational field [PDF]
Journal of Mathematical Physics, 1982 Stochastic field equations for linearized gravity are presented. The theory is compared with the usual quantum field theory and questions of Lorentz covariance are discussed. The classical radiation approximation is also presented.

Quantization of the Gravitational Field [PDF]
Annals of Physics, 1962 Abstract The scheme proposed in the preceding paper for the gauge-independent quantization of the electromagnetic field is here applied to the coordinate independent quantization of the gravitational field. Einstein's theory is first reformulated so as to avoid reference to a coordinate system. The quantization of the resulting theory is then carried

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 ...

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 ...

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 ...

Schrödinger Symmetry in Gravitational Mini-Superspaces
Universe, 2023 We prove that the simplest gravitational symmetry-reduced models describing cosmology and black hole mechanics are invariant under the Schrödinger group.

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

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

Journal 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
Universe, 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 ...
