CMB Constraints on Natural Inflation with Gauge Field Production
Khursid Alam, Koushik Dutta, Nur Jaman
The natural inflation model with a periodic cosine potential is ruled out by recent Planck 2018 data for the decay constant . If the Planck data is combi…
Gravitational wave background from quintessential inflation and NANOGrav data
Barnali Das, Nur Jaman, M Sami
We investigate the production process of induced gravity waves due to large scalar fluctuations in the paradigm of quintessential inflation. We numerically solve the Mukhanov-Sasak…
Induced Gravitational Waves via Warm Natural Inflation
Miguel Correa, Mayukh R. Gangopadhyay, Nur Jaman +1
We analyze the spectrum of gravitational waves generated by the induced spectrum of tensor fluctuation during warm natural inflation. In our previous work it has been demonstrated…
Primordial Black-Hole Dark Matter via Warm Natural Inflation
Miguel Correa, Mayukh R. Gangopadhyay, Nur Jaman +1
We report on a study of the natural warm inflationary paradigm (WNI). We show two important new results arise in this model. One is that the observational constraints on the primor…
What is needed of a scalar field if it is to unify inflation and late time acceleration ?
Nur Jaman, M. Sami
Quintessential inflation refers to scenarios in which a single scalar field is used to describe inflation and late-time acceleration. This review is dedicated to the framework of q…
The paradigm of warm quintessential inflation and spontaneous baryogenesis
Soumen Basak, Sukannya Bhattacharya, Mayukh R. Gangopadhyay +3
In this paper, we consider a scenario of spontaneous baryogenesis in a framework of warm quintessential inflation where the residual inflaton field, left out after warm inflation,…
Baryogenesis in the paradigm of quintessential inflation
Safia Ahmad, Antonio De Felice, Nur Jaman +2
We explore the possibility of baryogenesis in the framework of quintessential inflation. We focus on the model independent features of the underlying paradigm and demonstrate that…
Emergence of cosmological scaling behavior in asymptotic regime
M. A. Skugoreva, M. Sami, N. Jaman
In this paper we consider a scalar field system with a class of potentials given by the expression, ; for which $…
Bigravity and Horndeski gravity connected by a disformal coupling
Radouane Gannouji, Md. Wali Hossain, Nur Jaman +1
In this paper, we have studied bi-gravity theory in a very specific limit where we focused only on one degree of freedom generated by the massive graviton. We have analyzed the mod…
Braneworld inflation with effective α-attractor potential
Nur Jaman, Kairat Myrzakulov
In this paper, we study inflation with α-attractor potential in the RS braneworlds where high energy corrections to the Friedmann equation facilitate slow roll. In this scenario, w…
