A model of tachyon inflation is proposed in the framework of holographic cosmology. The
model is based on a holographic braneworld scenario with a D3-brane located at the …

We study inflation driven by the tachyon field in the holographic braneworld by assuming the
second slow-roll parameter η is constant. The parameter η can be either defined by the …

Within the framework of tachyon inflation, we consider different steep potentials and check
their viability in light of the Planck 2015 data. We see that in this scenario, the inverse power …

We study a tachyon cosmological model based on the dynamics of a 3-brane in the bulk of
the second Randall–Sundrum model extended to more general warp functions. A well …

We analyze a tachyon cosmological model based on the dynamics of a 3-brane in the bulk
of the second Randall–Sundrum model. This model contains extended general warp …

We study inflation in a model with constant second slow-roll parameter $\eta $. In this case,
the Hubble expansion rate equation has analytical solutions describing four possible …

We study the cosmological particle creation in the tachyon inflation based on the D-brane
dynamics in the Randall-Sundrum (RSII) model extended to include matter in the bulk. The …

After a brief introduction to the AdS/CFT holography, a tachyon inflation will be discussed in
the framework of holographic cosmology. The model is based on a holographic braneworld …

We derive a generalized expressions for the scalar power spectrum and the observational
parameters of inflation (the scalar spectral index $ n_ {\rm s} $ and the tensor-to-scalar ratio …

We study Chaplygin gas as a candidate for inflation in the context of braneworld inflationary
model. We investigate this model in the framework of the Randall–Sundrum type II …
