, 2005 We study `hilltop' inflation, in which inflation takes place near a maximum of the potential. Viewed as a model of inflation after the observable Universe leaves the horizon (observable inflation) hilltop inflation is rather generic.

Basics and Highlights in Fundamental Physics, 2001 A macroscopic universe may emerge naturally from a Planck cell fluctuation by unfolding through a stage of exponential expansion towards a homogeneous cosmological background. Such primordial inflation requires a large and presumably infinite degeneracy at the Planck scale, rooted in the unbounded negative gravitational energy stored in conformal ...

Primordial black holes from single field models of inflation [PDF]
, 2017 Primordial black holes (PBH) have been shown to arise from high peaks in the matter power spectra of multi-field models of inflation. Here we show, with a simple toy model, that it is also possible to generate a peak in the curvature power spectrum of ...

Curvaton reheating: an application to braneworld inflation [PDF]
, 2003 The curvaton was introduced recently as a distinct inflationary mechanism for generating adiabatic density perturbations. Implicit in that scenario is that the curvaton offers a new mechanism for reheating after inflation, as it is a form of energy ...

Journal of Cosmology and Astroparticle Physics, 2022 Abstract We study the impact of (generalized) cuscuton models on standard single scalar field inflation. Generalized cuscuton models are characterized by spatial covariant gravity where a scalar degree of freedom is made non dynamical, and there are just two tensor degrees of freedom.

Inflation analysis in Indonesia: A monetary or fiscal phenomenon? [PDF]
Industrija, 2023 This study seeks to identify and analyze the effects of monetary phenomena (operationalized with the quantity of money supply and interest rates), fiscal phenomena (operationalized with fiscal deficits), and the implementation of inflation-targeting ...

Inflation hardship, gender, and mental health
SSM: Population Health, 2023 Inflation hit a 40 year high in the United States in 2022, yet the impact of inflation related hardships on distress is poorly understood, particularly the impact on women, whose income is already more limited.

Does Inflation Reduce Air Pollution? Evidence from Indonesia [PDF]
E3S Web of Conferences, 2021 Inflation could likely cause devastating impacts where high inflation can harmful economic and social circumstances. However, only limited studies try to find the impact of inflation on the quality of air.
