It introduces a novel inflation mechanism using electric tachyon dynamics in moduli-stabilized string frameworks, expanding the landscape of inflation models.
Findings
Electric fields can slow tachyon decay, enabling inflation.
Feasibility depends on geometry, easier in certain backgrounds.
Provides conditions for tachyon-driven inflation in string theory.
Abstract
We propose that under certain conditions the universal open string tachyon can drive topological inflation in moduli stabilised frameworks. Namely, the presence of electric field in the world volume of the D-brane can slow down its decay leading to a phenomenological model of inflation. The conditions for inflation to take place are difficult to satisfy in the standard warped deformed conifold but easier to realise in other geometries.
