Non-Gaussian features from the inverse volume corrections in loop quantum cosmology
, 2012 In this paper we study the non-Gaussian features of the primordial fluctuations in loop quantum cosmology with the inverse volume corrections. The detailed analysis is performed in the single field slow-roll inflationary models.

Enemies: uneasy accompaniments in late life Ennemis : accompagnements de fin de vie difficiles
Journal of the Royal Anthropological Institute, Volume 31, Issue S1, Page 128-144, April 2025.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 ...

Gravity's rainbow: A bridge between LQC and DSR
Physics Letters B, 2017 The doubly special relativity (DSR) theories are constructed in order to take into account an observer-independent length scale in special relativity framework. Gravity's rainbow is a simple generalization of DSR theories to incorporate gravity.

Effective actions for loop quantum cosmology in fourth-order gravity
European Physical Journal C: Particles and Fields, 2021 Loop quantum cosmology (LQC) is a theory which renders the Big Bang initial singularity into a quantum bounce, by means of short-range repulsive quantum effects at the Planck scale.

Gravitational wave generation in loop quantum cosmology
, 2011 We calculate the full spectrum, as observed today, of the cosmological gravitational waves generated within a model based on loop quantum cosmology. It is assumed that the universe, after the transition to the classical regime, undergoes a period of ...

Dreaming Ubuntu: Jungian Studies, Forgiveness, and Jung’s Recalcitrant Fourth
Journal of Analytical Psychology, Volume 70, Issue 2, Page 235-256, April 2025.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 ...

From the conformal anomaly to the Virasoro algebra
Proceedings of the London Mathematical Society, Volume 130, Issue 4, April 2025.Abstract The conformal anomaly and the Virasoro algebra are fundamental aspects of two‐dimensional conformal field theory and conformally covariant models in planar random geometry. In this article, we explicitly derive the Virasoro algebra from an axiomatization of the conformal anomaly in terms of real determinant lines, one‐dimensional vector spaces

Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract Current observations show that a significant fraction of the Universe is composed of dark energy and dark matter. In this paper, the simultaneous effects of these dark sectors on the Euler–Heisenberg black hole are investigated, using the quintessence matter field and perfect fluid to model them. In particular, the black hole's thermodynamics,

Dynamical coherent states and physical solutions of quantum cosmological bounces
, 2007 A new model is studied which describes the quantum behavior of transitions through an isotropic quantum cosmological bounce in loop quantum cosmology sourced by a free and massless scalar field.
