1. Fluctuations through a vibrating bounce / Brandenberger, Robert ; Liang, Qiuyue ; Ramos, Rudnei O. ; Zhou, Siyi
We study the evolution of cosmological perturbations in a nonsingular bouncing cosmology with a bounce phase which has superimposed oscillations of the scale factor. [...]

3. Particle production in Ekpyrotic scenarios / Hipólito-Ricaldi, W.S. ; Brandenberger, Robert ; Ferreira, Elisa G.M. ; Graef, L.L.
We consider Parker particle production in the Ekpyrotic scenario (in particular in the New Ekpyrotic model) and show that the density of particles produced by the end of the phase of Ekpyrotic contraction can be sufficient to lead to a hot state of matter after the bounce. [...]

4. Holographic curvature perturbations in a cosmology with a space-like singularity / Ferreira, Elisa G.M. ; Brandenberger, Robert
We study the evolution of cosmological perturbations in an anti-de-Sitter (AdS) bulk through a cosmological singularity by mapping the dynamics onto the boundary conformal fields theory by means of the AdS/CFT correspondence. [...]

5. Preheating and entropy perturbations in axion monodromy inflation / McDonough, Evan ; Moghaddam, Hossein Bazrafshan ; Brandenberger, Robert H.
We study the preheating of gauge fields in a simple axion monodromy model and compute the induced entropy perturbations and their effect on the curvature fluctuations. [...]

7. Cosmological perturbations across an S-brane / Brandenberger, Robert H. ; Kounnas, Costas ; Partouche, Hervé ; Patil, Subodh P. ; et al
Space-filling S-branes can mediate a transition between a contracting and an expanding universe in the Einstein frame. [...]
