Passing through the bounce in the ekpyrotic models
Jerome Martin, Patrick Peter, Nelson Pinto Neto +1
By considering a simplified but exact model for realizing the ekpyrotic scenario, we clarify various assumptions that have been used in the literature. In particular, we discuss th…
Damping of inhomogeneities in neutralino dark matter
Dominik J. Schwarz, Stefan Hofmann, Horst Stoecker
The lightest supersymmetric particle, most likely the neutralino, might account for a large fraction of dark matter in the Universe. We show that the primordial spectrum of density…
Cosmic acceleration from effective forces?
Dominik J. Schwarz, Winfried Zimdahl, Alexander B. Balakin +1
Accelerated expansion of the Universe may result from an anti-frictional force that is self-consistently exerted on cold dark matter (CDM). Cosmic anti-friction is shown to give ri…
Higher order corrections to primordial spectra from cosmological inflation
Dominik J. Schwarz, Cesar A. Terrero-Escalante, Alberto A. Garcia
We calculate power spectra of cosmological perturbations at high accuracy for two classes of inflation models. We classify the models according to the behaviour of the Hubble dista…
Damping scales of neutralino cold dark matter
Stefan Hofmann, Dominik J. Schwarz, Horst Stoecker
The lightest supersymmetric particle, most likely the neutralino, might account for a large fraction of dark matter in the Universe. We show that the primordial spectrum of density…
Revisiting the calculations of inflationary perturbations
C. A. Terrero-Escalante, D. J. Schwarz, A. A. Garcia
We present a new approximation scheme that allows us to increase the accuracy of analytical predictions of the power spectra of inflationary perturbations for two specific classes…
