Viability of f(R) Theories with Additional Powers of Curvature
Anthony W. Brookfield, Carsten van de Bruck, Lisa M. H. Hall
We consider a modified gravity theory, f(R)=R-a/R^n+bR^m, in the metric formulation, which has been suggested to produce late time acceleration in the Universe, whilst satisfying l…
Cosmic D-Strings and Vortons in Supergravity
Ph. Brax, C. van de Bruck, A. C. Davis +1
Recent developments in string inspired models of inflation suggest that D-strings are formed at the end of inflation. Within the supergravity model of D-strings there are 2(n-1) ch…
Fermionic Zero Modes of Supergravity Cosmic Strings
Ph. Brax, C. van de Bruck, A. C. Davis +1
Recent developments in string theory suggest that cosmic strings could be formed at the end of brane inflation. Supergravity provides a realistic model to study the properties of s…
