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 …

It is commonly assumed that the energy density of the Universe was dominated by radiation
between reheating after inflation and the onset of matter domination 54,000 years later …

A bstract The Swampland Distance Conjecture (SDC) states that, as we move towards an
infinite distance point in moduli space, a tower of states becomes exponentially light with the …

A bstract We examine the mechanism of moduli stabilization by fluxes in the limit of a large
number of moduli. We conjecture that one cannot stabilize all complex-structure moduli in F …

A bstract We construct supersymmetric AdS 4 vacua of type IIB string theory in
compactifications on orientifolds of Calabi-Yau threefold hypersurfaces. We first find explicit …

We analyze to which extent the KKLT proposal for the construction of de Sitter vacua in
string theory is quantitatively controlled. Our focus is on the quality of the 10d supergravity …

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 give an overview of moduli stabilization in compactifications of string theory. We
summarize current methods for construction and analysis of vacua with stabilized moduli …

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 …
