Gravitational field of the quantized electromagnetic plane wave

General Relativity and Gravitation, 1987
The quantum and classical descriptions of an electro-magnetic field are connected by the correspondence principle. We consider the electromagntic field as a source for gravity and compare the metrics due to a classical and quantized electromagnetic field. The quantization of the source demands the quantization of gravity.

Interaction of a two-level atom with a quantized radiation field in the presence of a gravitational field

Physical Review A, 2000
The system of a two-level atom interacting with a quantized radiation field in a gravitational field is studied by making use of a dynamical algebraic method. A full quantum treatment of the internal and external dynamics of the atom is given and an exact expression for the time evolution operator of the system is obtained.

Stochastic Quantization of the Linearized Gravitational Field

1984
The stochastic quantization scheme of Parisi and Wu [1] exhibits a Euclidean quantum field ψ(x) as the stationary limit with respect to a fictitious time t of the stochastic relaxation process defined for t ≥ 0 by the Langevin equation $$\frac{\partial } {{\partial t}}\,\psi \,(t,x)\, = \, - \,\frac{{\delta S[\psi (t,x)]}} {{\delta \psi (t,x)}}\, +

The exact solution of a two-level atom moving in a quantized travelling light field and a gravitational field

Chinese Physics, 2001
We adopt a dynamical algebraic approach to study the system of a two-level atom moving in a quantized travelling light field and a gravitational field with a multiphoton interaction. The exact solution of the system is obtained and used to discuss the influence of the gravitational field on the collapses and revivals of atomic population, sub ...

The Two-body Problem in the Theory of the Quantized Gravitational Field

Proceedings of the Physical Society. Section A, 1956
The equations of the two-body problem of general relativity are derived by a Hamiltonian method based on an expansion of the general covariant Lagrangian in powers of the gravitational constant and by employing the techniques and the viewpoint of quantum field theory. It is found that, within the approximation in which they have so far been calculated,

A model for the influence of quantised fields on the gravitational collapse of a dust cloud

Classical and Quantum Gravity, 1989
Summary: The influence of the vacuum expectation value of the energy-momentum tensor of a conformally invariant free quantised field on the spherically symmetric gravitational collapse of a dust cloud is investigated in the approximation that the effects of particle creation can be neglected. The methods used are adopted from the early universe studies

Quantization of the gravitational field: The presentation of gravity as the Hilbert space of the quantized system

Il Nuovo Cimento B Series 11, 1980
In the last three decades or so many methods to quantize the gravitational field were developed but all of them have led to no, or very little progress. All of these methods are shared in the idea of treating gravitation in a similar fashion to either the electromagnetic field or the Yang-Mills field.

BRS Symmetry in Stochastic Quantization of the Gravitational Field

1990
We study stochastic quantization of gravity in terms of a BRS invariant canonical operator formalism. By introducing artificially canonical momentum variables for the original field variables, a canonical formulation of stochastic quantization is proposed in a sense that the Fokker-Planck hamiltonian is the generator of the fictitious time translation.

Gupta-Bleuler quantization of the electromagnetic field in curved space-times with applications to gravitational photon interferometry

2023
Unlike Newton’s theory of gravitation, Einstein’s theory of general relativity predicts that Earth’s gravitational field induces phase shifts not only in massive particles but also in single photons. Whereas gravitationally induced interference in massive particles has been demonstrated multiple times, experiments have yet to reach the sensitivities ...
