Gravitational production of completely dark photons with nonminimal couplings to gravity

Journal of High Energy Physics
Dark photons are a theorized massive spin-1 particle which can be produced via various mechanisms, including cosmological gravitational particle production (GPP) in the early universe.

Primordial black holes in Gauss-Bonnet gravity

Physics Letters B
In this paper, we investigate the production of primordial black holes (PBHs) during the preheating era. Indeed, the amplification of field fluctuations can lead to the amplification of curvature perturbations.

Kosmologi Ibnu Arabi dan Covid-19: Relasi dan Solusi Alternatif dalam Tasawuf Filosofi

Esoterik: Jurnal Akhlak dan Tasawuf, 2021
This paper aims to discuss Ibn Arabi's cosmological thinking in relation to the Covid-19 phenomenon. According to Ibn Arabi, the cosmological phenomenon is a reality that does not appear by itself but comes from God.

Bianchi Type V Viscous Fluid Cosmological Models in Presence of Decaying Vacuum Energy

, 2012
Bianchi type V viscous fluid cosmological model for barotropic fluid distribution with varying cosmological term $\Lambda$ is investigated. We have examined a cosmological scenario proposing a variation law for Hubble parameter $H$ in the background of ...

Growing Pre‐Service Teachers' Well‐Being Capacity: Comparing the Perspectives of Teacher Education Programme Administrators and Teacher Candidates Across Canada

Future in Educational Research, EarlyView.
ABSTRACT Recognising the importance of addressing teacher development in the early career stages, our study examined programmatic considerations within teacher education programmes in Canada to determine the extent to which teacher preparation included support for and promotion of teacher well‐being as part of their pre‐service teaching development ...

Cosmological implications of Kalb-Ramond-like particles

Journal of High Energy Physics
The Kalb-Ramond field is an antisymmetric, rank-two tensor field which most notably appears in the context of string theory, but has largely been unexplored in the context of cosmology.

Holographic (De)confinement Transitions in Cosmological Backgrounds

, 2011
For type IIB supergravity with a running axio-dilaton, we construct bulk solutions which admit a cosmological background metric of Friedmann-Robertson-Walker type.

Neutrino puzzle: Anomalies, interactions, and cosmological tensions [PDF]

Physical Review D, 2019
New physics in the neutrino sector might be necessary to address anomalies between different neutrino oscillation experiments. Intriguingly, it also offers a possible solution to the discrepant cosmological measurements of H0 and σ8.

Posidonius' Cosmology

Perspectiva Filosófica, 2020
Posidonius incorporated important concepts of Peripatetic physics into his system. Posidonius adopted a finitist cosmological model where the extra- cosmic void was not infinite but just as large as the cosmos’ size at the time of the conflagration (F 84/97a E ̶ K).

Spiritual Cannibalism in HRD: How Workplace Spirituality Devours Sacred Traditions

Human Resource Development Quarterly, EarlyView.
ABSTRACT This paper interrogates how the discourse of workplace spirituality in human resource development (HRD) operates as a tool of colonization. Through a systematic review of 48 articles published between 1997 and March 2025, the study uncovers recurring patterns of spiritual appropriation in which non‐Western traditions are detached from their ...
