Prospects of inflation with perturbed throat geometry
Amna Ali, R. Chingangbam, Sudhakar Panda +1
We study brane inflation in a warped deformed conifold background that includes general possible corrections to the throat geometry sourced by coupling to the bulk of a compact Cal…

Proper acceleration, geometric tachyon and dynamics of a fundamental string near D branes
Ashok Das, Sudhakar Panda, Shibaji Roy
We present a detailed analysis of our recent observation that the origin of the geometric tachyon, which arises when a D-brane propagates in the vicinity of a stack of coinciden…

Prospects of inflation in delicate D-brane cosmology
Sudhakar Panda, M. Sami, Shinji Tsujikawa
We study D-brane inflation in a warped conifold background that includes brane-position dependent corrections for the nonperturbative superpotential. Instead of stabilizing the vol…
