Chameleonic inflation

Understand

We attempt to incorporate inflation into a string theory realization of the chameleon mechanism.

• Previously, it was found that the volume modulus, stabilized by the supersymmetric potential used by Kachru, Kallosh, Linde and Trivedi (KKLT) and with the right choice of parameters, can generically work as a chameleon.
• In this paper, we ask whether inflation can be realized in the same model.
• We find that we need a large extra dimensions set-up, as well as a semi-phenomenological deformation of the Kahler potential in the quantum region.
