Inflationary potentials yielding constant scalar perturbation spectral indices
Alberto Vallinotto, Edmund J. Copeland, Edward W. Kolb +2
We explore the types of slow-roll inflationary potentials that result in scalar perturbations with a constant spectral index, i.e., perturbations that may be described by a single…

Singular tachyon kinks from regular profiles
E. J. Copeland, P. M. Saffin, D. A. Steer
We demonstrate how Sen's singular kink solution of the Born-Infeld tachyon action can be constructed by taking the appropriate limit of initially regular profiles. It is shown that…
