A model with two periods of inflation
Simon Schettler, Jurgen Schaffner-Bielich
A scenario with two subsequent periods of inflationary expansion in the very early universe is examined. The model is based on a potential motivated by symmetries being found in fi…
Detecting quark matter in the early universe by gravitational waves
Simon Schettler, Tillmann Boeckel, Jurgen Schaffner-Bielich
For large baryochemical potential, strongly interacting matter might undergo a first order phase transition at temperatures T ~ 100-200 MeV. Within standard cosmology, however, the…
The Cosmological QCD Phase Transition Revisited
Simon Schettler, Tillmann Boeckel, Jurgen Schaffner-Bielich
The QCD phase diagram might exhibit a first order phase transition for large baryochemical potentials. We explore the cosmological implications of such a QCD phase transition in th…
Imprints of the QCD Phase Transition on the Spectrum of Gravitational Waves
Simon Schettler, Tillmann Boeckel, Jurgen Schaffner-Bielich
We have investigated effects of the QCD phase transition on the relic GW spectrum applying several equations of state for the strongly interacting matter: Besides the bag model, wh…
