Density perturbations arising from multiple field slow-roll inflation
S. Groot Nibbelink, B. J. W. van Tent
In this paper we analyze scalar gravitational perturbations on a Robertson-Walker background in the presence of multiple scalar fields that take values on a (geometrically non-triv…

Construction and analysis of anomaly-free supersymmetric SO(2N)/U(N) sigma-models
S. Groot Nibbelink, T. S. Nyawelo, J. W. van Holten
This paper discusses a procedure for the consistent coupling of gauge- and matter superfields to supersymmetric sigma-models on symmetric coset spaces of Kaehler type. We exhibit t…
