flux compactification


String theory




Flux compactifications are a variant of the Kaluza-Klein mechanism in physics.

One way of achieving moduli stabilization for KK-compactifications of string theory backgrounds is to consider higher gauge fields in the compact space. Their higher field strength/curvature forms parameterize mass terms for the compactification moduli and hence can, under suitable conditions, stabilize them.
