Emergence of Warm Inflation in Curved Space‐Time between Accelerating Branes
Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020 It appears that having our own brane to somehow interact with other branes could give rise to quite an interesting system and that interaction could lead to some observable effects. We consider the question of whether or not these signatures of interaction between the branes can be observed. To answer this question, we investigate the effect induced by

Inflationary Baryogenesis [PDF]
, 2001 In this letter we explore the possibility of creating the baryon asymmetry of the universe during inflation and reheating due to the decay of a field associated with the inflaton.

WIMPs, FIMPs, and Inflaton phenomenology via reheating, CMB and ∆N eff
Journal of High Energy Physics, 2023 In this paper, we extensively analyzed the reheating dynamics after inflation and looked into its possible implication on dark matter (DM) and inflaton phenomenology.

Holography of a composite inflaton [PDF]
Journal of High Energy Physics, 2010 We study the time evolution of a brane construction that is holographically dual to a strongly coupled gauge theory that dynamically breaks a global symmetry through the generation of an effective composite Higgs vev. The D3/D7 system with a background magnetic field or non-trivial gauge coupling (dilaton) profile displays the symmetry breaking.

Running non-minimal inflation with stabilized inflaton potential
European Physical Journal C: Particles and Fields, 2017 In the context of the Higgs model involving gauge and Yukawa interactions with the spontaneous gauge symmetry breaking, we consider $$\lambda \phi ^4$$ λ ϕ 4 inflation with non-minimal gravitational coupling, where the Higgs field is identified as the ...

INFLATON FIELD AND PRIMORDIAL BLACKHOLE [PDF]
International Journal of Modern Physics D, 2002 Primordial black hole formation has been studied using an inflaton field with a variable cosmological term as the potential.

Simple realization of inflaton potential on a Riemann surface
Physics Letters B, 2014 The observation of the B-mode in the cosmic microwave background radiation combined with the so-called Lyth bound suggests the trans-Planckian variation of the inflaton field during inflation.

Shrinking the Warm Little Inflaton
Journal of High Energy Physics, 2023 We show that warm inflation can be successfully realized in the high temperature regime through dissipative interactions between the inflaton and a single fermionic degree of freedom, provided that the latter’s mass is an oscillatory function of the ...

Inflatonic baryogenesis with large tensor mode
Physics Letters B, 2015 We consider a complex inflaton field with a CP asymmetric term for its potential. This CP asymmetric term produces the global charge of the inflaton after inflation.
