We extend the idea of mimetic gravity to a Randall–Sundrum II braneworld model. As for the
4-dimensional mimetic gravity, we isolate the conformal degree of freedom of 5-dimensional …

We present a tachyonic field inflationary model in a teleparallel framework. We show that
tachyonic coupled with the f (T) gravity model can describe the inflation era in which f (T) is …

We extend the idea of unimodular gravity to the modified f (R, T) theories. A new class of
cosmological solutions, that the unimodular constraint on the metric imposes on the f (R, T) …

We consider two noncanonical scalar fields [tachyon and Dirac–Born–Infeld (DBI)] with E-
model type of the potential. We study cosmological inflation in these models to find possible …

We study the primordial perturbations and reheating process in the models where the Gauss–
Bonnet (GB) term is nonminimally coupled to the canonical and noncanonical (DBI and …

In this article, our prime objective is to study the inflationary paradigm in the context of the
generalized tachyon (GTachyon) living on the world volume of a non-BPS string theory. The …

We study tachyon inflation in the presence of the superpotential as an inflationary potential.
We study the primordial perturbations and their non-Gaussian feature in the equilateral …

We study mimetic gravity in the presence of a Dirac–Born–Infeld (DBI)-like term, which is a
non-canonical setup of the scalar field's derivatives. We consider two general cases with …

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 cosmological dynamics of an extended gravitational theory that gravity is coupled
non-minimally with derivatives of a dark energy component and there is also a …
