The Robustness of n_s < 0.95 in Racetrack Inflation
Ph. Brax, Stephen C. Davis, M. Postma
A spectral index n_s < 0.95 appears to be a generic prediction of racetrack inflation models. Reducing a general racetrack model to a single-field inflation model with a simple pot…
D-term Uplifted Racetrack Inflation
Philippe Brax, Anne-Christine Davis, Stephen C. Davis +2
It is shown that racetrack inflation can be implemented in a moduli stabilisation scenario with a supersymmetric uplifting D-term. The resulting model is completely described by an…
Zero modes on cosmic string loops
Marieke Postma, Betti Hartmann
We study the spectrum of fermionic modes on cosmic string loops. We find no fermionic zero modes nor massive bound states - this implies that vortons stabilized by fermionic curren…
