Dark Dimension With (Little) Strings Attached

Fortschritte der Physik, EarlyView.
Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

Foundations of Ghost Stability

Fortschritte der Physik, EarlyView.
Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.

Enemies: uneasy accompaniments in late life Ennemis : accompagnements de fin de vie difficiles

Journal of the Royal Anthropological Institute, EarlyView.
Against a phenomenological orientation to ageing as path or course, a contrastive frame is offered around a figure termed the enemy. Four distinctive ethnographic fragments are utilized: (1) a Polish‐Jewish migrant to Canada in her late eighties who listens continually to the radio and worries over the malign forces in the world that the radio ...

Supersymmetric quantum solution for FRW cosmological model with matter [PDF]

Rev.Mex.Fis. 48 (2002) 112-117, 2001
Using technique of supersymmetric quantum mechanics we present new cosmological quantum solution, in the regime for FRW cosmological model using a barotropic perfect fluid as matter field.

Dreaming Ubuntu: Jungian Studies, Forgiveness, and Jung’s Recalcitrant Fourth

Journal of Analytical Psychology, EarlyView.
Abstract Jung’s recalcitrant fourth comes in from a place of opposition, demanding that what has been neglected be considered. It is in the spirit of the fourth that the author examines the use of Ubuntu in Jungian literature, cautioning against a decontextualized appropriation of the notion that overlooks its diverse interpretations and usages ...

Purpose and Providence in Evolutionary Perspective: Considerations for Theological Anthropology in Light of Biocultural Evolution and Genetic Engineering

The Heythrop Journal, EarlyView.
Abstract We argue here that bringing insights from evolution and bioengineering to bear on traditional accounts of divine providence helps to illustrate just how complex providence is and how difficult it is to achieve. While other non‐human animals might exhibit greater agency in creation and its evolutionary development than has traditionally been ...

Note on Quantum Newtonian Cosmology [PDF]

arXiv, 2005
It is well known that, for pressureless matter, Newtonian and relativistic cosmologies are equivalent. We show that this equivalence breaks down in the quantum level. In addition, we find some cases for which quantum Newtonian cosmology can be related to quantum cosmology in (2+1) dimensions.

The simplicity of physical laws

Noûs, EarlyView.
Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

Lessons from the void: What Boltzmann brains teach

Analytic Philosophy, EarlyView.
Abstract Some physical theories predict that almost all brains in the universe are Boltzmann brains, that is, short‐lived disembodied brains that are accidentally assembled as a result of thermodynamic or quantum fluctuations. Physicists and philosophers of physics widely regard this proliferation as unacceptable, and so take its prediction as a basis ...

The Quantum Mechanics of Cosmology [PDF]

arXiv, 2018
Notes from the lectures by the author at the 7th Jerusalem Winter School 1990 on Quantum Cosmology and Baby Universes. The lectures covered quantum mechanics for closed systems like the universe, generalized quantum mechanics, time in quantum mechanics, the quantum mechanics spacetime, and practical quantum cosmology.
