Converting entropy to curvature perturbations after a cosmic bounce
Speaker(s): Angelika Fertig
Abstract: In this talk, I will show how entropy perturbations created during a contracting phase and converted into adiabatic/curvature perturbations after a bounce form the dominant contribution to the observed temperature fluctuations in the CMB. In [arXiv:1607.05663] we have studied two-field bouncing c... read more

Alternatives to Inflation – Non-Minimal Ekpyrosis & Conflation
Speaker(s): Angelika Fertig
Abstract: In this talk I derive the evolution equations for two scalar fields with non-canonical field space metric up to third order in perturbation theory, employing the covariant formalism. These equations can be used to calculate the local bi- and trispectra of the non-minimal ekpyrotic model. Remarkably,... read more
