Scalar Induced Gravitational Waves from Warm Inflation
  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 discuss a
model of warm inflation in which large curvature perturbations are generated at
the small scales because of inflaton dissipation. These overdense perturbations
then collapse at later epoch to form primordial black holes, as was studied in
our earlier work (Ref. \cite{Arya:2019wck}), and therefore may also act as a
source to the second-order tensor perturbations. In this study, we calculate
the spectrum of these secondary gravitational waves from our warm inflationary
model. We find that our model leads to a generation of scalar induced
gravitational waves (SIGW) over a frequency range ($1-10^6$) Hz. Further, we
discuss the detection possibilities of these SIGWs, taking in account the
sensitivity of different ongoing and future gravitational wave experiments.
