Dynamics of Rolling Massive Scalar Field Cosmology
Pravabati Chingangbam, Tabish Qureshi
We study the inflationary consequences of the rolling massive scalar field in the braneworld scenario with a warped metric. We find that in order to fit observational constraints t…
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…
Aspects of Tachyonic Inflation with Exponential Potential
M. Sami, Pravabati Chingangbam, Tabish Qureshi
We consider issues related to tachyonic inflation with exponential potential. We find exact solution of evolution equations in the slow roll limit in FRW cosmology. We also carry o…
