Quantum Field Theory of 3+1 Dimensional BTZ Gravity: Graviton Self-Energy, Axion Interactions, and Dark Matter in the Ultrahyperfunction Framework

Axioms
We present a comprehensive quantum field theoretical analysis of graviton self-energy and mass generation in 3+1 dimensional BTZ black hole spacetime, incorporating axion interactions within the framework of dark matter theory. Using a novel mathematical

Quantum black holes in scalar–tensor gravity: a Green function approach

European Physical Journal C: Particles and Fields
It is well-known that a Lagrangian resembling scalar–tensor gravity naturally emerges from string theory in the low-energy limit. This suggests that a scalar–tensor theory intrinsically inhabits precious information about quantum gravitational effects ...

Loop Quantum Gravity

Living Reviews in Relativity, 1998
The problem of finding the quantum theory of the gravitational field, and thus understanding what is quantum spacetime, is still open. One of the most active of the current approaches is loop quantum gravity. Loop quantum gravity is a mathematically well-

The Quantum Theory of Gravitation: I Quantization of Free Fields - II Proof of Renormalizability

, 2019
Quantization of Free Fields: The non-interacting field belonging to a new {\bf SO(1,3)\/} gauge field theory equivalent to General Relativity is canonically quantized in the Lorentz gauge and the physical Fock space for free gauge particles is constructed.
