Phase space quantization and Loop Quantum Cosmology: a Wigner function for the Bohr-compactified real line [PDF]
, 2008 We give a definition for the Wigner function for quantum mechanics on the Bohr compactification of the real line and prove a number of simple consequences of this definition. We then discuss how this formalism can be applied to loop quantum cosmology. As

Gravitational Fluctuations as an Alternative to Inflation II. CMB Angular Power Spectrum
Universe, 2019 Power spectra always play an important role in the theory of inflation. In particular, the ability to reproduce the galaxy matter power spectrum P ( k ) and the CMB temperature angular power spectrum C l ’s to high accuracy is often ...

Quantum Gravity: A Primer for Philosophers. [PDF]
, 2008 ‘Quantum Gravity’ does not denote any existing theory: the field of quantum gravity is very much a ‘work in progress’. As you will see in this chapter, there are multiple lines of attack each with the same core goal: to find a theory that unifies, in ...

Reports in Advances of Physical SciencesThis paper aims to demonstrate that modern cosmology has overlooked the systematic and holistic aspects of the universe’s evolution. It is based on the notion that the primordial universe comprised a two-component quantum superfluid and a synthesis of ...

A DISCOURSE ANALYSIS THROUGH CORPUS LINGUISTICS ON THE CASE OF POPULAR SCIENCE BOOK THE GRAND DESIGN
Kajian Linguistik dan Sastra, 2016 This study aims to discover the theme of popular physics book, The Grand Design, through corpus linguistics and discourse analysis as well as how the authors of the book describe the field of study which in fact is not their main focus to work on.

A modal-Hamiltonian interpretation of quantum mechanics [PDF]
, 2008 The aim of this paper is to introduce a new member of the family of the modal interpretations of quantum mechanics. In this modal-Hamiltonian interpretation, the Hamiltonian of the quantum system plays a decisive role in the property-ascription rule that

Starobinsky potential and power suppression in hybrid loop quantum cosmology
Physics Letters BWe study the effect on the primordial tensor power spectrum of varying the number of e-folds during slow-roll inflation in Loop Quantum Cosmology with a Starobinsky potential. Using the hybrid quantization approach, we derive the effective mass governing

Measurements according to "Consistent Quantum Theory" [PDF]
, 2013 We critically evaluate the treatment of the notion of measurement in the Consistent Histories approach to quantum mechanics. We find such treatment unsatisfactory because it relies, often implicitly, on elements external to the provided formalism.

Pensamiento. Revista de Investigación e Información Filosófica, 2013 So far we can identify at least three concepts within modern cosmology that bring into debate the question of consciousness in the universe: 1) Fine Tuning; 2) The Anthropic Principle and 3) The Multiverse.
