Entanglement decoherence in a gravitational well according to the event formalism

New Journal of Physics, 2014
The event formalism is a nonlinear extension of quantum field theory designed to be compatible with the closed time-like curves that appear in general relativity.

Universal quantum modifications to general relativistic time dilation in delocalised clocks [PDF]

Quantum, 2020
The theory of relativity associates a proper time with each moving object via its world line. In quantum theory however, such well-defined trajectories are forbidden. After introducing a general characterisation of quantum clocks, we demonstrate that, in

Expansion evolution of nonhomogeneous metric with quantum-mechanically revisited fundamental metric tensor

Nuclear Physics B
To explore the properties of space and initial singularities in the context of general relativity, where spacetime becomes poorly defined and no longer belongs to a regular manifold, we examine the evolution of the expansion of timelike geodesic ...

Nonlocal teleparallel cosmology

European Physical Journal C: Particles and Fields, 2017
Even though it is not possible to differentiate general relativity from teleparallel gravity using classical experiments, it could be possible to discriminate between them by quantum gravitational effects. These effects have motivated the introduction of

Rotation and Spin in Physics

, 2010
We delineate the role of rotation and spin in physics, discussing in order Newtonian classical physics, special relativity, quantum mechanics, quantum electrodynamics and general relativity. In the latter case, we discuss the generalization of the Kepler

Global one-dimensionality conjecture within quantum general relativity [PDF]

, 2008
A simple quantum gravity model, based on a new conjecture within the canonically quantized 3 + 1 general relativity, is presented. The conjecture states that matter fields are functionals of an embedding volume form only and reduces the quantum ...

Locality Is Dead! Long Live Locality!

Frontiers in Physics, 2020
Several decades of theory and experiment into EPR correlations have led to the widely held belief that reality is non-local, in spite of the fact that this violates special relativity.

Quantum Gravity If Non-Locality Is Fundamental

Entropy, 2022
I take non-locality to be the Michelson–Morley experiment of the early 21st century, assume its universal validity, and try to derive its consequences.

Effective Field Theory of Gravity: Leading Quantum Gravitational Corrections to Newtons and Coulombs Law

, 2008
In this paper we consider general relativity and its combination with scalar quantum electrodynamics (QED) as an effective quantum field theory at energies well below the Planck scale.

Stochastic Gravity: Theory and Applications

Living Reviews in Relativity, 2004
Whereas semiclassical gravity is based on the semiclassical Einstein equation with sources given by the expectation value of the stress-energy tensor of quantum fields, stochastic semiclassical gravity is based on the Einstein-Langevin equation, which ...
