Inflation and axion cosmology

Physics Letters B, 1988
Abstract It is argued that the standard constraint ƒ⪷10 12 GeV in the axion theory and related constraints in the theories of other weakly interacting scalar fields do not apply in many versions of the inflationary universe scenario.

Medical Lysenkoism

Journal of Evaluation in Clinical Practice, Volume 31, Issue 5, August 2025.
Abstract Medicine is a compound field composed of science and art. The (necessary) degree to which the latter is involved opens medicine, in particular, to the introduction of ideas which do not, by their very nature, submit to confirmation or confutation as do the various methods of traditional science.

Lectures on string theory and cosmology

, 2004
In these lectures I review recent attempts to apply string theory to cosmology, including string cosmology and various models of brane cosmology. In addition, the review includes an introduction to inflation as well as a discussion of transplanckian ...

Clockwork axions in cosmology. Is chromonatural inflation chrononatural?

Journal of High Energy Physics, 2018
Many cosmological models rely on large couplings of axions to gauge fields. Examples include theories of magnetogenesis, inflation on a steep potential, chiral gravitational waves, and chromonatural inflation. Such theories require a mismatch between the

Constraining the Break of Spatial Diffeomorphism Invariance with Planck Data

, 2017
The current most accepted paradigm for the early universe cosmology, the inflationary scenario, shows a good agreement with the recent Cosmic Microwave Background (CMB) and polarization data.

Energy Storage and Environmental Justice: A Critical Examination of a Proposed Pumped Hydropower Facility in Goldendale, Washington

Antipode, Volume 57, Issue 4, Page 1236-1258, July 2025.
Abstract Renewable energy sources such as solar and wind produce electricity intermittently, creating challenges in balancing electricity supply and demand for increasingly renewable‐dominated grids. This is driving efforts to increase energy storage infrastructure, such as pumped hydroelectric power storage (pumped storage).

Scaling solutions for dilaton quantum gravity

Physics Letters B, 2017
Scaling solutions for the effective action in dilaton quantum gravity are investigated within the functional renormalization group approach. We find numerical solutions that connect ultraviolet and infrared fixed points as the ratio between scalar field ...

Variation of Model‐Predicted Reconnection Voltages Applied to Uranus' Dayside Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract Uranus provides a key missing piece for fundamentally understanding solar wind‐magnetospheric interactions due to its location in the outer solar system. Whether the viscous‐like interaction overtakes global magnetic reconnection as the dominant process at the magnetopause of the outer planets remains unresolved.

Will quantum cosmology resurrect chaotic inflation model?

, 2016
The single field chaotic inflation model with a monomial power greater than one seems to be ruled out by the recent Planck and WMAP CMB data while Starobinsky model with a higher curvature term seems to be a viable model.

Inflation in the standard cosmological model

Comptes Rendus. Physique, 2015
Abstract The inflationary paradigm is now part of the standard cosmological model as a description of its primordial phase. While its original motivation was to solve the standard problems of the hot big bang model, it was soon understood that it offers a natural theory for the origin of the large-scale structure of the universe.
