The European Physical Journal C, 2023 AbstractUsing arguments from holography we propose that the deviation of the cosmological spectral index $$n_S$$ n S of scalar fluctuations from unity may be controlled almost entirely by the critical exponent $$\eta $$ η of

Parity-violation in bouncing cosmology
Journal of High Energy Physics, 2023 We investigate the possibility of the enhancement of parity-violation signal in bouncing cosmology. Specifically, we are interested in deciding which phase should generate the most significant parity-violation signals.

International 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.

New 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.

Chaos and Order: Contemporary Cosmology and Myth
Etnoantropološki Problemi, 2020 The paper offers a definition of cosmology and its connections with mythology, and presents contemporary theories as a secular mythical narrative suitable for anthropological analysis. The paper is dedicated to emphasizing the folklore characteristics of

Tachyon field in loop cosmology
Physics 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 ...

International 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 ...

Equivalence of Models in Loop Quantum Cosmology and Group Field Theory
Universe, 2019 The paradigmatic models often used to highlight cosmological features of loop quantum gravity and group field theory are shown to be equivalent, in the sense that they are different realizations of the same model given by harmonic cosmology.

Indigenous Shamanic Worldviews as Dialogical Eco-Cosmology
Lagoonscapes, 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 ...
