A geometric origin of the Bohm potential from Einstein–Cartan spin–torsion coupling

Academia Quantum
A deterministic quantum-gravity framework is proposed that embeds Bohmian mechanics within the spin–torsion geometry of Einstein–Cartan–Kibble–Sciama theory.

Einstein-Gilbert-Straus solution of Einstein field equations: Timelike geodesic congruence with conventional and quantized fundamental metric tensor

Nuclear Physics B
In a cosmic background characterized by inhomogeneity, anisotropy, and spherical symmetry, a nonsingular solution to the Einstein field equations is established through the application of both conventional and quantized fundamental metric tensor.

Lattice Chern-Simons-Maxwell theory and its chirality

Journal of High Energy Physics
We define and solve the U(1) Chern-Simons-Maxwell theory on spacetime lattice, with an emphasis on the chirality of the theory. Realizing Chern-Simons theory on lattice has been a problem of interest for decades, and over the years it has gradually ...

Generally covariant quantization and the Dirac field

, 2007
Canonical Hamiltonian field theory in curved spacetime is formulated in a manifestly covariant way. Second quantization is achieved invoking a correspondence principle between the Poisson bracket of classical fields and the commutator of the ...

Explaining Leibniz equivalence as difference of non-inertial appearances: dis-solution of the Hole Argument and physical individuation of point-events [PDF]

, 2006
”The last remnant of physical objectivity of space-time” is disclosed in the case of a continuous family of spatially non-compact models of general relativity (GR).

Spiral Compactification with torsion-monodromy locking

Physics Open
We present a unified geometric framework in which spiral compactification with torsion and monodromy locking defines a minimal invariant structure governing spectra, interactions, and stability in a five dimensional Kaluza–Klein type setting.

The noise of gravitons

, 2020
© 2020 World Scientific Publishing Company. 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.

Canonical Path Integral Quantization of Einstein's Gravitational Field

General Relativity and Gravitation, 2002
The connection between the canonical and the path integral formulations of Einstein's gravitational field is discussed using the Hamilton - Jacobi method. Unlike conventional methods, it is shown that our path integral method leads to obtain the measure of integration with no $δ$- functions, no need to fix any gauge and so no ambiguous deteminants will

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
