Oscillons from String Moduli
Stefan Antusch, Francesco Cefala, Sven Krippendorf +3
A generic feature of string compactifications is the presence of many scalar fields, called moduli. Moduli are usually displaced from their post-inflationary minimum during inflati…
Combining High-scale Inflation with Low-energy SUSY
Stefan Antusch, Koushik Dutta, Sebastian Halter
We propose a general scenario for moduli stabilization where low-energy supersymmetry can be accommodated with a high scale of inflation. The key ingredient is that the stabilizati…
Towards Matter Inflation in Heterotic String Theory
Stefan Antusch, Koushik Dutta, Johanna Erdmenger +1
Recently, a class of inflation models in supergravity with gauge non-singlet matter fields as the inflaton has been proposed. It is based on a `tribrid' structure in the superpoten…
Chaotic Inflation in Supergravity with Heisenberg Symmetry
Stefan Antusch, Mar Bastero-Gil, Koushik Dutta +2
We propose the introduction of a Heisenberg symmetry of the Kahler potential to solve the problems with chaotic inflation in supergravity, as a viable alternative to the use of shi…
Coupling the Superstring to a D-Brane Ramond-Ramond Background
Stefan Antusch
We propose a new approach for coupling the type II superstring to the Ramond-Ramond background of D-branes in the RNS formalism, alternative to introducing RR vertex operators. It…
