Phenomenological Inflationary Model in Supersymmetric Quantum Cosmology
Universe, 2022 We consider the effective evolution of a phenomenological model from FLRW supersymmetric quantum cosmology with a scalar field. The scalar field acts as a clock and inflaton.

Strong dynamics and inflation: A review
Nuclear Physics B, 2015 In this article, we review how strong dynamics can be efficiently employed as a viable alternative to study the mechanism of cosmic inflation. We examine single-field inflation in which the inflaton emerges as a bound state stemming from various strongly

Signals of Bursts from the Very Early Universe
The Astrophysical JournalWe consider possible observable signals from explosive events in the very early Universe, dubbed “bursts.” These could be expected in connection with massive black hole or “baby Universe” formation.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Key Findings: An assimilation methodology is established for the Tomorrow.io microwave sounder (TMS) flying on CubeSats in sun‐synchronous and inclined orbits, and in all cloud scenes. The TMS has a significant impact on weather forecast lead times up to 3 days in the Tropics in a research‐quality numerical weather prediction setting, and yields water ...

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model
Systems Research and Behavioral Science, EarlyView.ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

Dissipative quintessential cosmic inflation
Physics of the Dark UniverseIn this paper we construct a dissipative quintessential cosmic inflation. For this purpose, we add a multiplicative dissipative term in the standard quintessence field Lagrangian. We consider the specific form of dissipation as the time integral including the Hubble parameter and an arbitrary function that describes the dissipative properties of the ...

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.

Cosmic strings from Tribrid inflation
Journal of Cosmology and Astroparticle PhysicsAbstract Tribrid inflation is a class of supersymmetric inflation models where the scalar component of a matter superfield, or a D-flat direction of matter fields, drives inflation. Similar to Hybrid inflation, the end of inflation is reached when a “waterfall field”, which was stabilized during inflation at a field value where the ...
