Natural Braneworld Inflation in Light of Recent Results from Planck and BICEP2
Ishwaree P. Neupane
In this paper we report on a major theoretical observation in cosmology. We present a concrete cosmological model for which inflation has natural beginning and natural ending. Infl…
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 (…
Cosmology of a Friedmann-Lamaître-Robertson-Walker 3-brane, Late-Time Cosmic Acceleration, and the Cosmic Coincidence
Ciaran Doolin, Ishwaree P. Neupane
A late epoch cosmic acceleration may be naturally entangled with cosmic coincidence -- the observation that at the onset of acceleration the vacuum energy density fraction nearly c…
We Probably Live On An Inflating Brane-World
Ishwaree P. Neupane
Brane-world models where observers are trapped within the thickness of a 3-brane offer novel perspectives on gravitation and cosmology. In this essay, I would argue that the proble…
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…
