Nuclear Physics, 2023 In this work, we study warm inflationary scenario based on a deformation of R2 gravity. We start considering Rp and assume p=2(1+δ) with δ≪1 so that we simply obtain warm R2 inflation when setting δ=0. We then derive the potential in the Einstein frame and consider a dissipation parameter of the form Γ=C1T with C1 being a coupling parameter.

Dollars for Drops: Abatement Cost of Water for Irrigation in the Colorado River Basin
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT The Colorado River is a lifeline for more than 40 million people in the western United States. However, with climate change diminishing snowpacks in the Rocky Mountains and increasing demands from agriculture and urban areas, the river's flow has become insufficient to meet all the competing needs.

Dynamics of polynomial Chaplygin gas warm inflation
European Physical Journal C: Particles and Fields, 2017 In the present work, we study the consequences of a recently proposed polynomial inflationary potential in the context of the generalized, modified, and generalized cosmic Chaplygin gas models. In addition, we consider dissipative effects by coupling the

Journal of Cosmology and Astroparticle PhysicsAbstract Multi-natural inflation is studied in the context of warm inflation. We study the warm multi-natural inflation scenario with both linear and cubic temperature-dependent dissipation coefficients. The model is motivated by axion-like inflation models with coupling to non-Abelian gauge fields through a dimension-five ...

Constraint on the Higgs-Dilaton Potential via Warm Inflation in Two-Time Physics
Advances in High Energy Physics, 2022 Within the SP2,R symmetry, the two-time model (2T model) has six dimensions with two dimensions of time and the dilaton field that can be identified as inflaton in a warm inflation scenario with potential of the form ~ϕ4.

Towards a reliable effective field theory of inflation
Physics Letters B, 2021 We present the first quantum field theory model of inflation that is renormalizable in the matter sector, with a super-Hubble inflaton mass and sub-Planckian field excursions, which is thus technically natural and consistent with a high-energy completion

Warm Quasi-Single Field Inflation
, 2018 We study quasi-single field inflation with a warm inflation background. The thermal effects at small scales can sufficiently enhance the magnitude of the primordial standard clock signal.

Trans-Planckian effects in warm inflation [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 We study the effect of a non-trivial vacuum prescription on warm inflation observables, namely the power spectrum of the comoving curvature perturbation. Non-trivial choice of vacuum, can provide information about trans-Planckian physics. Traditionally, the initial condition for inflation is chosen to be the usual Bunch-Davies vacuum.
