Quantum fields as gravitational sources

The practice of setting quantum fields as sources for classical general relativity is examined. Several conceptual problems are identified which invalidate apparently innocuous equations. Alternative ways to links classical general relativity with quantum theory using Bohm’s theory are proposed. PACS numbers: 12.90.+b, 03.65.Ta, 04.20.Cv Submitted to: Class. Quantum Grav. Quantum fields as grav...

2 a “ Running ” Gravitational Constant ?

If the gravitational interaction is unified with the electro-weak and strong interactions at a mass M = 10 15 GeV, the evolution of Newton's constant must differ from its classical (general relativistic) form. We can model such behavior by introducing an ad hoc dependence on ℓn(s/4m 2), where s is the usual cm energy between two protons. We can then predict the observable effects for relativist...

Quantum-mechanical generation of gravitational waves in braneworld

We study the quantum-mechanical generation of gravitational waves during inflation on a brane embedded in a five-dimensional anti-de Sitter bulk. To make the problem well-posed, we consider the setup in which both initial and final phases are given by a de Sitter brane with different values of the Hubble expansion rate. Assuming that the quantum state is in a de Sitter invariant vacuum in the i...

The Hubble Constant from the Gravitational Lens

We present a refined gravitational lens model of the four-image lens system B1608+656 based on new and improved observational constraints: (i) the three independent time-delays and flux-ratios from Very Large Array (VLA) observations, (ii) the radio-image positions from Very Large Baseline Array (VLBA) observations, (iii) the shape of the deconvolved Einstein Ring from optical and infrared Hubb...

Primordial Black Holes as a Probe of the Early Universe and a Varying Gravitational Constant

We discuss recent developments in the study of primordial black holes, focussing particularly on their formation and quantum evaporation. Such studies can place important constraints on models of the early Universe. An especially interesting development has been the realization that such constraints may be severely modified if the value of the gravitational “constant” G varies with cosmological...
