On the Choice of Variable for Quantization of Conformal GR

Universe
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.

On Special Re-quantization of a Black Hole

, 2011
Quantized expressions for the gravitational energy and momentum are derived from a linearized theory of teleparallel gravity. The derivation relies on a second-quantization procedure that constructs annihilation and creation operators for the graviton ...

Dynamical Ambiguities in Singular Gravitational Field

, 1997
We consider particle dynamics in singular gravitational field. In 2d spacetime the system splits into two independent gravitational systems without singularity.

The Noise of Gravitons

, 2020
We show that when the gravitational field is treated quantum-mechanically, it induces fluctuations -- noise -- in the lengths of the arms of gravitational wave detectors.

Quantized 2d Dilaton Gravity and Black Holes [PDF]

, 1995
We have examined a modified dilaton gravity whose action is separable into the kinetic and the cosmological terms for the sake of the quantization. The black hole solutions survive even in the quantized theory, but the ADM mass of the static solution is ...

QUANTIZATION OF THE GRAVITATIONAL FIELD. THEORETICAL AND EXPERIMENTAL SUBSTANTIATION OF THE GRAVITATIONAL-ELECTROMAGNETIC RESONANCE. THE PHYSICAL NATURE OF THE QUANTUM OF THE GRAVITATIONAL FIELD.WHY THE SPEED OF LIGHT IN VACUUM IS CONSTANT

Collection of scientific works of Odesa Military Academy, 2022
It is shown that gravitating objects that are at rest, or move without acceleration, create a standing gravitational wave in space. The length of this wave is a quantization step of the gravitational field. It is proportional to the mass of the gravitating object.

Spectrum of Gravitational Waves in Krein Space Quantization [PDF]

, 2012
The main goal of this paper is to derive the primordial power spectrum for the scalar perturbations generated as a result of quantum fluctuations during an inflationary pe- riod by an alternative approach of field quantization[1-3].

Crossed products, conditional expectations and constraint quantization

Nuclear Physics B
Recent work has highlighted the importance of crossed products in correctly elucidating the operator algebraic approach to quantum field theories. In the gravitational context, the crossed product simultaneously promotes von Neumann algebras associated ...

Towards the topological quantization of classical mechanics

, 2008
We consider the method of topological quantization for conservative systems with a finite number of degrees of freedom. Maupertuis' formalism for classical mechanics provides an appropriate scenario which permit us to adapt the method of topological ...

How to Solve Quantum Nonlinear Abelian Gauge Theory in Two Dimension in the Heisenberg Picture [PDF]

, 1998
The new method based on the operator formalism proposed by Abe and Nakanishi is applied to the quantum nonlinear abelian gauge theory in two dimension. The soluble models in this method are extended to wider class of quantum field theories. We obtain the
