A Note on Inflation with Tachyon Rolling on the Gauss-Bonnet Brane
B. C. Paul, M. Sami
In this paper we study the tachyonic inflation in brane world cosmology with Gauss-Bonnet term in the bulk. We obtain the exact solution of slow roll equations in case of exponenti…

Steep Inflation followed by Born-Infeld Reheating
M. Sami, N. Dadhich, Tetsuya Shiromizu
We discuss a model in which high energy brane corrections allow a single scalar field to describe inflation at early epochs and quintessence at late times. The reheating mechanism…

Cosmological Aspects of Rolling Tachyon
M. Sami, Pravabati Chingangbam, Tabish Qureshi
We examine the possibility of rolling tachyon to play the dual roll of inflaton at early epochs and dark matter at late times. We argue that enough inflation can be generated with…
