Phenomenological implications of an alternative Hamiltonian constraint for quantum cosmology
, 2005 In this paper we review a model based on loop quantum cosmology that arises from a symmetry reduction of the self dual Plebanski action. In this formulation the symmetry reduction leads to a very simple Hamiltonian constraint that can be quantized ...

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.

Phantasmic Encounters in the Arctic: Haunting Materialities Beyond the Ghosts of War
Anthropology of Consciousness, EarlyView.ABSTRACT In the vast north, ghostly experiences are common for locals and outsiders alike. Here, we explore how cultural‐natural attributes, like remoteness and extreme seasonal variation, compound experiences of the haunting in visceral ways. This provides the Arctic region with an unusually pronounced baseline of other‐than‐human agency, which in the

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 ...

, 2006 We apply the formalism of quantum cosmology to models containing a phantom field. Three models are discussed explicitly: a toy model, a model with an exponential phantom potential, and a model with phantom field accompanied by a negative cosmological ...

Pre-inflationary universe in loop quantum cosmology [PDF]
, 2017 The evolutions of the flat FLRW universe and its linear perturbations are studied systematically in the dressed metric approach of LQC. When it is dominated by the kinetic energy of the inflaton at the quantum bounce, the evolution of the background can ...

Ψ-epistemic quantum cosmology? [PDF]
Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics, 2016 This paper provides a prospectus for a new way of thinking about the wavefunction of the universe: a $\Psi$-epistemic quantum cosmology. We present a proposal that, if successfully implemented, would resolve the cosmological measurement problem and simultaneously allow us to think sensibly about probability and evolution in quantum cosmology.

Asia Pacific Viewpoint, EarlyView.ABSTRACT This research note advances the idea of a talanoa epistemology. Many readers will be familiar with talanoa as an Indigenous mode of communication practiced in the Pacific. Variations of talanoa have been applied in COP constellations, inter‐faith meetings, Pacific diplomacy, conflict resolution, and as a research method.

Classical and quantum cosmology of minimal massive bigravity
Physics Letters B, 2016 In a Friedmann–Robertson–Walker (FRW) space–time background we study the classical cosmological models in the context of recently proposed theory of nonlinear minimal massive bigravity.
