On Locality in Quantum General Relativity and Quantum Gravity [PDF]

Foundations of Physics, 1996
The physical concept of locality is first analyzed in the special relativistic quantum regime, and compared with that of microcausality and the local commutativity of quantum fields. Its extrapolation to quantum general relativity on quantum bundles over

Constraints on Gravitation from Causality and Quantum Consistency

Advances in High Energy Physics, 2018
We examine the role of consistency with causality and quantum mechanics in determining the properties of gravitation. We begin by examining two different classes of interacting theories of massless spin 2 particles—gravitons.

Complexifier Coherent States for Quantum General Relativity [PDF]

Classical and Quantum Gravity, 2002
Recently, substantial amount of activity in Quantum General Relativity (QGR) has focussed on the semiclassical analysis of the theory. In this paper we want to comment on two such developments: 1) Polymer-like states for Maxwell theory and linearized ...

Quantum information and general relativity [PDF]

Fortschritte der Physik, 2004
The Einstein-Podolsky-Rosen paradox (1935) is reexamined in the light of Shannon's information theory (1948). The EPR argument did not take into account that the observers' information was localized, like any other physical object.

Quantum general relativity and Hawking radiation [PDF]

, 2002
In a previous paper we have set up the Wheeler-DeWitt equation which describes the quantum general relativistic collapse of a spherical dust cloud. In the present paper we specialize this equation to the case of matter perturbations around a black hole ...

Preferred foliation effects in Quantum General Relativity [PDF]

Classical and Quantum Gravity, 2010
We investigate the infrared (IR) effects of Lorentz violating terms in the gravitational sector using functional renormalization group methods similar to Reuter and collaborators.

Nonlinear optical simulation of the post-Newton Schrödinger equation [PDF]

Nature Communications
One of the grand open problems of modern physics is the unification of Einstein’s general relativity and quantum mechanics. This challenge has been approached by the greatest physicists but there is still no complete theory and experimental evidence ...
