Moduli Evolution in the Presence of Matter Fields and Flux Compactification

Understand

We provide a detailed analysis of the dynamics of moduli fields in the KKLT scenario coupled to a Polonyi field, which plays the role of a hidden matter sector field.

• It was previously shown that such matter fields can uplift AdS vacua to Minkowski or de Sitter vacua.
• Additionally, we take a background fluid into account (which can be either matter or radiation), which aids moduli stabilisation.
• Our analysis shows that the presence of the matter field further aids stabilisation, due to a new scaling regime.
