Gauss-Bonnet assisted braneworld inflation in light of BICEP2 and Planck data
Ishwaree P. Neupane
Motivated by the idea that quantum gravity corrections usually suppress the power of the scalar primordial spectrum (E-mode) more than the power of the tensor primordial spectrum (…
De Sitter brane-world, localization of gravity, and the cosmological constant
Ishwaree P. Neupane
Cosmological models with a de Sitter 3-brane embedded in a five-dimensional de Sitter spacetime (dS5) give rise to a finite 4D Planck mass similar to that in Randall-Sundrum (RS) b…
Warped compactification to de Sitter space
Ishwaree P. Neupane
We explore in detail the prospects of obtaining a four-dimensional de Sitter universe in classical supergravity models with warped and time-independent extra dimensions, presenting…
Warped compactification on curved manifolds
Ishwaree P. Neupane
The characterization of a six- (or seven)-dimensional internal manifold with metric as having positive, zero or negative curvature is expected to be an important aspect of warped c…
Accelerating universe from warped extra dimensions
Ishwaree P Neupane
Accelerating universe or the existence of a small and positive cosmological constant is probably the most pressing obstacle as well as opportunity to significantly improving the mo…
Extra dimensions, warped compactifications and cosmic acceleration
Ishwaree P. Neupane
We report on explicit cosmological solutions within the framework of an inflating de Sitter brane embedded in five- and ten-dimensional bulk spacetimes. In the specific example we…
