Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.Abstract Jupiter's auroral regions have previously been defined by broad‐scale auroral structures, but these are typically obscured by the wide array of temporal variability observed at timescales between minutes and days, making it difficult to understand the underlying magnetospheric biases driving these brightness differences.

Quantum Cosmology of Quadratic f(R) Theories with a FRW Metric
Advances in Mathematical Physics, 2017 We study the quantum cosmology of a quadratic fR theory with a FRW metric, via one of its equivalent Horndeski type actions, where the dynamic of the scalar field is induced.

Cosmic Inflation, Quantum Information and the Pioneering Role of John S Bell in Cosmology
Universe, 2019 According to the theory of cosmic inflation, the large scale structures observed in our Universe (galaxies, clusters of galaxies, Cosmic Background Microwave—CMB—anisotropy…) are of quantum mechanical origin. They are nothing but vacuum

Model building with non-compact cosets
Physics Letters B, 2016 We explore Goldstone boson potentials in non-compact cosets of the form SO(n,1)/SO(n). We employ a geometric approach to find the scalar potential, and focus on the conditions under which it is compact in the large field limit.

Reports in Advances of Physical SciencesThis paper aims to demonstrate that modern cosmology has overlooked the systematic and holistic aspects of the universe’s evolution. It is based on the notion that the primordial universe comprised a two-component quantum superfluid and a synthesis of ...

Primordial Gravitational Waves and Reheating in a New Class of Plateau-Like Inflationary Potentials
Universe, 2018 We study a new class of inflation model parametrized by the Hubble radius, such that aH∝exp(−αφ)n. These potentials are plateau-like, and reduce to the power-law potentials in the simplest case n=2.

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.
