Idea

Flux compactifications are Kaluza-Klein compactification where a gauge field or higher gauge field has non-trivial field strength, hence “generalized electromagnetic flux” in the fiber-spaces, whose repulsive force counteracts the collapsing force of gravity on the compact fiber spaces.

Applied to supergravity this may in particular yield perturbative string theory vacua.

One way of achieving moduli stabilization for KK-compactifications in Einstein-Maxwell theory or supergravity/string theory is to consider gauge fields and/or higher gauge fields in the compact space. Their (higher) field strength/curvature forms (“fluxes”) parameterize mass terms for the compactification moduli and hence may, under suitable conditions, stabilize them.
