Trans-Planckian censorship and inflationary cosmology [PDF]

open access: yesPhysical Review D, 2019
We study the implications of the recently proposed Trans-Planckian Censorship Conjecture (TCC) for early universe cosmology and in particular inflationary cosmology.

WKB-type Approximation to Noncommutative Quantum Cosmology [PDF]

open access: yes, 2007
In this work, we develop and apply the WKB approximation to several examples of noncommutative quantum cosmology, obtaining the time evolution of the noncommutative universe, this is done starting from a noncommutative quantum formulation of cosmology ...

Indigenous Shamanic Worldviews as Dialogical Eco-Cosmology

open access: yesLagoonscapes, 2021
This article deals with indigenous shamanic worldviews and indigenous knowledge as dialogical eco-cosmology. It shows the relevance of eco-cosmology as local indigenous ecological and spiritual knowledge in the context of global biodiversity and ...

f(T) teleparallel gravity and cosmology [PDF]

open access: yesReports on progress in physics. Physical Society, 2015
Over recent decades, the role of torsion in gravity has been extensively investigated along the main direction of bringing gravity closer to its gauge formulation and incorporating spin in a geometric description.

Cosmological networks

open access: yesNew Journal of Physics, 2014
Networks often represent systems that do not have a long history of studies in traditional fields of physics, albeit there are some notable exceptions such as energy landscapes and quantum gravity. Here we consider networks that naturally arise in cosmology.

RASTALL COSMOLOGY [PDF]

open access: yesInternational Journal of Modern Physics: Conference Series, 2012
We review the difficulties of the generalized Chaplygin gas model to fit observational data, due to the tension between background and perturbative tests. We argue that such issues may be circumvented by means of a self-interacting scalar field representation of the model.

Bison Herds and Indian Corn: Interspecies Matriarchs and Revitalised Foodways in the Fort Peck Reservation

open access: yesGender &History, Volume 34, Issue 3, Page 915-930, October 2022., 2022
Abstract For Turtle Island's Buffalo Nations – those sharing a common food system with bison at the centre – herds are a food source, as well as relatives and pillars of cultural continuity. Bison give life while exemplifying it to their tribal relatives who learned from the herds’ matriarchal organisation.

Tachyon field in loop cosmology

open access: yesPhysics Letters B, 2020
The evolutionary pictures of tachyon field in modified loop cosmology have been investigated. We present the dynamical behavior of the tachyon field associated with an exponential potential and find that the pre-inflation dynamics are very similar in ...

Dynamical behavior of interacting dark energy in loop quantum cosmology

open access: yes, 2010
The dynamical behaviors of interacting dark energy in loop quantum cosmology are discussed in this paper. Based on defining three dimensionless variables, we simplify the equations of the fixed points.

THE COSMOLOGICAL TESTS [PDF]

open access: yesInternational Journal of Modern Physics A, 2001
Recent observational advances have considerably improved the cosmological tests, adding to the lines of evidence, and showing that some issues under discussion just a few years ago may now be considered resolved or irrelevant. Other issues remain, however, and await resolution before the great program of testing the relativistic Friedmann–Lemaître ...
