  • Scalar induced gravitational waves from warm inflation 
    Arya, Richa; MISHRA, ARVIND KUMAR (Elsevier B.V., 2022-09)
    Stochastic gravitational waves can be induced from the primordial curvature perturbations generated during inflation, through scalar–tensor mode coupling at the second order of cosmological perturbation theory. Here we ...
  • Primordial black holes dark matter and secondary gravitational waves from warm Higgs-G inflation 
    Arya, Richa; Jain, Rajeev Kumar; MISHRA, ARVIND KUMAR (IOP Publishing, 2024-02)
    We explore the role of dissipative effects during warm inflation leading to the small-scale enhancement of the power spectrum of curvature perturbations. In this paper, we specifically focus on non-canonical warm inflationary ...
