QCD phase transition and primordial density perturbations
J. Ignatius, Dominik J. Schwarz
We analyze the effect of primordial density perturbations on the cosmic QCD phase transition. According to our results hadron bubbles nucleate at the cold perturbations. We call th…
Precision of inflationary predictions and recent CMB anisotropy data
Dominik J. Schwarz, Jerome Martin, Alain Riazuelo
Inflationary predictions of the cosmic microwave background anisotropy are often based on the slow-roll approximation. We study the precision of these predictions and compare them…
Cosmic anti-friction and accelerated expansion
Winfried Zimdahl, Dominik J. Schwarz, Alexander B. Balakin +1
We explain an accelerated expansion of the present universe, suggested from observations of supernovae of type Ia at high redshift, by introducing an anti-frictional force that is…
Slow-roll inflation and CMB anisotropy data
Jerome Martin, Alain Riazuelo, Dominik J. Schwarz
We emphasize that the estimation of cosmological parameters from cosmic microwave background (CMB) anisotropy data, such as the recent high resolution maps from BOOMERanG and MAXIM…
New exact solutions for inflationary cosmological perturbations
Jerome Martin, Dominik J. Schwarz
From a general ansatz for the effective potential of cosmological perturbations we find new, exact solutions in single-scalar-field inflation: a three parameter family of exact inf…
