Descripción
We study possible string theory compactifications which, in the low-energy limit, describe chaotic inflation with a stabilizer field. On the one hand, we analyze a recent proposal in type IIA string theory involving D6-branes. After integrating out the relevant closed-string moduli consistently, tachyonic directions arise during inflation which cannot be lifted. This is ultimately due to the symmetries of the Kahler potential. Motivated by this, we search for viable stabilizer fields in the complex structure sector of type II theories. Since instantons break the shift symmetry of the relevant K\"ahler potential in the vicinity of the Ginzburg-Landau point, we argue that complex structure moduli may be viable candidates when stabilized away from the large complex structure limit.
