Chiral cosmic strings in supergravity
Rachel Jeannerot, Marieke Postma
We consider F and D-term cosmic strings formed in supersymmetric theories. Supersymmetry is broken inside the string core, but restored outside. In global SUSY, this implies the ex…

Majorana zero modes
Rachel Jeannerot, Marieke Postma
We derive the zero mode solutions for a Majorana fermion in the background of a cosmic string and contrast it with the zero mode solution for a (neutral) Dirac fermion. A Majorana…

Curvaton scenario with low scale inflation revisited
Marieke Postma
In its simplest form the curvaton paradigm requires the Hubble parameter during inflation to be bigger than $10^8 \GeV$, but this bound may be evaded in non-standard settings. In t…
