We review applications of string theory to cosmology, from primordial times to the present-
day accelerated expansion. Starting with a brief overview of cosmology and string …

These lecture notes provide a pedagogical introduction, with exercises, to the techniques
used in attempts to construct vacua with stabilized moduli in string theory. The reader is only …

A bstract The KKLT scenario, one of the few ideas to realize dS vacua in string theory,
consists of two steps: the first involves the construction of a supersymmetric AdS vacuum …

We argue that dS vacua in the LARGE-volume scenario of type IIB string theory are
vulnerable to various unsuppressed curvature, warping and gs corrections. We work out in …

We investigate whether an accelerating universe can be realized as an asymptotic late-time
solution of Friedmann–Lemaître–Robertson–Walker (FLRW)-cosmology with multifield …

The extensive computer-aided search applied in Bena et al.(The tadpole problem, 2020) to
find the minimal charge sourced by the fluxes that stabilize all the (flux-stabilizable) moduli …

A bstract We compute the flux-induced F-term potential in 4d F-theory compactifications at
large complex structure. In this regime, each complex structure field splits as an axionic field …

A bstract The tadpole conjecture suggests that the complete stabilization of complex
structure deformations in Type IIB and F-theory flux compactifications is severely obstructed …

A bstract The large volume scenario (LVS) for de Sitter compactifications of the type IIB string
is, at least in principle, well protected from various unknown corrections. The reason is that …

A bstract It has been argued that orientifold vacua with fluxes in type IIA string theory can
achieve moduli stabilisation and arbitrary decoupling between the AdS and KK scales upon …
