Mass spectrum of type IIB flux compactifications — comments on AdS vacua and conformal dimensions [PDF]
In this note we study the mass spectrum of type IIB flux compactifications. We first give a general discussion of the mass matrix for F-term vacua in four-dimensional N $$ \mathcal{N} $$ = 1 supergravity theories and then specialize to type IIB Calabi ...

Maximal supergravity from IIB flux compactifications [PDF]
Using a recently proposed group-theoretical approach, we explore novel gaugings of maximal supergravity in four dimensions with gauge group embeddings that can be generated by fluxes of IIB string theory. The corresponding potentials are positive without

Exceptional flux compactifications [PDF]
AbstractWe consider type II (non-)geometric flux backgrounds in the absence of brane sources, and construct their explicit embedding into maximal gaugedD= 4 supergravity. This enables one to investigate the critical points, mass spectra and gauge groups of such backgrounds.

Warped flux compactification and brane gravity [PDF]
We find a simple exact solution of 6-dimensional braneworld which captures some essential features of warped flux compactification, including a warped geometry, compactification, a magnetic flux, and one or two 3-brane(s). In this setup we analyze how the Hubble expansion rate on each brane changes when the brane tension changes.

Smearing orientifolds in flux compactifications can be OK [PDF]
We present explicit examples of supergravity solutions corresponding to backreacting localised (non-intersecting) O6 planes in flux reductions of massive IIA supergravity and address some criticism towards the very existence of such solutions.

Small flux superpotential in F-theory compactifications [PDF]
We investigate whether a class of models describing F-theory compactifications admits a specific type of flux vacua with an exponentially small vacuum expectation value of the superpotential, by generalizing a method recently developed in Type IIB flux ...

Nonlinear dynamics of flux compactification
We study the nonlinear evolution of unstable flux compactifications, applying numerical relativity techniques to solve the Einstein equations in D dimensions coupled to a q-form field and positive cosmological constant. We show that initially homogeneous

F-theory flux vacua and attractor equations
We examine the vacuum structure of 4D effective theories of moduli fields in spacetime compactifications with quantized background fluxes. Imposing the no-scale structure for the volume deformations, we numerically investigate the distributions of flux ...
