Tachyonic perturbations in AdS orbifolds
Cyril Cartier, Ruth Durrer
We show that scalar as well as vector and tensor metric perturbations in the Randall-Sundrum II braneworld allow normalizable tachyonic modes, i.e., possible instabilities. These i…

Scalar perturbations in an -regularised cosmological bounce
Cyril Cartier
We consider the evolution of scalar perturbations in a class of non-singular bouncing universes obtained with higher-order corrections to the low-energy bosonic string action. We s…
