Loop Quantum Cosmology: A Status Report [PDF]

, 2011
The goal of this article is to provide an overview of the current state of the art in loop quantum cosmology for three sets of audiences: young researchers interested in entering this area; the quantum gravity community in general; and, cosmologists who ...

Enchanting the Otherwise: Magical Realism and the Gendered Ontologies of Organizational Becoming

Gender, Work &Organization, EarlyView.
ABSTRACT This paper enacts a feminist‐posthumanist reimagining of gender as ontological disturbance, using magical realism not as metaphor but as epistemological method. Rejecting representational logics and the managerial rationalities of organizational realism, we advance gender not as identity or role but as spectral interference—a transversal ...

Quantum BPS cosmology

Classical and Quantum Gravity
Abstract There has been much discussion about the initial conditions of the early Universe in the context of quantum theory. In this paper, we construct the wave function and probability distribution by adopting the quantum version of the BPS equation instead of the usual Wheeler–DeWitt equation in a minisuperspace quantum cosmology with

Minisuperspace Examples of Quantization Using Canonical Variables of the Ashtekar Type: Structure and Solutions

, 1995
The Ashtekar variables have been use to find a number of exact solutions in quantum gravity and quantum cosmology. We investigate the origin of these solutions in the context of a number of canonical transformations (both complex and real) of the basic ...

Theological Doctrines as Scientific Theories? Thinking along with and beyond McGrath

International Journal of Systematic Theology, EarlyView.
Abstract McGrath's recent analysis of the parallels between scientific theory formation and the development of theological doctrine in The Nature of Christian Doctrine (OUP, 2024) is insightful and largely compelling, but also raises some questions and areas for further exploration. First, there is a remarkable back‐and‐forth between uses of ‘doctrine’

NONCOMMUTATIVE QUANTUM MECHANICS AND QUANTUM COSMOLOGY [PDF]

International Journal of Modern Physics A, 2009
We present a phase-space noncommutative version of quantum mechanics and apply this extension to Quantum Cosmology. We motivate this type of noncommutative algebra through the gravitational quantum well (GQW) where the noncommutativity between momenta is shown to be relevant. We also discuss some qualitative features of the GQW such as the Berry phase.

Switching Internal Times and a New Perspective on the `Wave Function of the Universe’

Universe, 2019
Despite its importance in general relativity, a quantum notion of general covariance has not yet been established in quantum gravity and cosmology, where, given the a priori absence of coordinates, it is necessary to replace classical frames with ...

Magnetic properties of geraisites, the first tektite strewn field identified in Brazil

Meteoritics &Planetary Science, EarlyView.
Abstract Geraisites are a newly recognized class of tektite from Brazil. They occur as centimeter‐sized, elongated to subspherical bodies scattered across surface gravel and shallow subsurface layers within a ~90‐km‐long strewn field extending between the municipalities of São João do Paraíso and Curral de Dentro, near the border between the states of ...
