Observational Status of Zero-Point Length Cosmic Inflation [PDF]
Iranian Journal of Astronomy and AstrophysicsWe examine observational status of cosmological inflation with a zero-point length. By considering the zero-point length correction to the geometric part of the field equations, specially the Hubble parameter, we derive modified background equations ...

Thermal loop effects on large-scale curvature perturbation in the Higgs inflation
Journal of High Energy Physics, 2020 It is known that the Higgs potential in the Standard Model can drive a successful inflation as long as the Higgs field couples non-minimally to gravity.

Golden weapons and golden fetters: From the gold standard to the new geopolitics
The Economic History Review, EarlyView.Abstract This paper explores the historical relationship between monetary regimes, security concerns, and geopolitical tensions, particularly focusing on the role of gold. Throughout history, monetary systems have been deeply intertwined with international state systems and security provisions.

Insights into gravitinos abundance, cosmic strings and stochastic gravitational wave background
European Physical Journal C: Particles and FieldsIn this paper, we investigate D-term inflation within the framework of supergravity, employing the minimal Kähler potential. Following previous studies that revealed that this model can overcome the $$\eta $$ η -problem found in F-term models, we explore

Heavy-lifting of gauge theories by cosmic inflation
Journal of High Energy Physics, 2018 Future measurements of primordial non-Gaussianity can reveal cosmologically produced particles with masses of order the inflationary Hubble scale and their interactions with the inflaton, giving us crucial insights into the structure of fundamental ...

Uncovering the history of cosmic inflation from anomalies in cosmic microwave background spectra
European Physical Journal C: Particles and Fields, 2022 We propose an inflationary primordial feature model that can explain both the large and small-scale anomalies in the currently measured cosmic microwave background anisotropy spectra, revealing a clip of adventurous history of the Universe during its ...

City of God and the Duty of Just Memory
Modern Theology, EarlyView.Abstract In a recent essay, Richard Miller claims that Augustine presumes a duty to remember justly in his City of God. However, Miller's brief reference to a presumed duty of “just memory” does not fully explain how Augustine conceptualizes this duty or how it relates to his theological concerns.

Towards the physical vacuum of cosmic inflation
Physics Letters B, 2016 There have been long debates about the initial conditions of inflationary perturbations. In this work we explicitly show the decay of excited states during inflation via interactions from the renormalization group point of view. For this purpose, we note

Holographic realization of constant roll inflation and dark energy: An unified scenario
Physics Letters B, 2023 In the formalism of generalized holographic dark energy, the infrared cut-off LIR is generalized to the form, LIR=LIR(Lp,L˙p,L¨p,⋯,Lf,L˙f,L¨f,⋯,a,H,H˙,H¨,⋯), where Lp and Lf are the particle horizon and the future horizon, respectively (moreover, a is ...
