Quantum vacuum energy in general relativity [PDF]
European Physical Journal C: Particles and Fields, 2018 The paper deals with the scale discrepancy between the observed vacuum energy in cosmology and the theoretical quantum vacuum energy (cosmological constant problem).

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 ...

Deformed General Relativity and Quantum Black Holes Interior [PDF]
Universe, 2020 Effective models of black holes interior have led to several proposals for regular black holes. In the so-called polymer models, based on effective deformations of the phase space of spherically symmetric general relativity in vacuum, one considers a ...

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.

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 ...
