We present a brief overview of attempts to construct de Sitter vacua in string theory and
explain how the results of this 20-year endeavor could point to the fact that string theory …

We review recent progress in studying mesons within gauge/gravity duality, in the context of
adding flavour degrees of freedom to generalizations of the AdS/CFT correspondence. Our …

The past two decades have seen transformative advances in cosmology and string theory.
Observations of the cosmic microwave background have revealed strong evidence for …

A bstract In this paper we holographically study the strongly coupled dynamics of the field
theory on I-branes (D5 branes intersecting on a line). In this regime, the field theory …

We elaborate on the recent work of Moritz et al. where it is argued that anti‐brane uplifting in
KKLT models never leads to dS vacua. This is due to flattening effects in the effective …

Using a 10D lift of nonperturbative volume stabilization in type IIB string theory, we study the
limitations for obtaining de Sitter vacua. Based on this we find that the simplest Kachru …

We review recent progress in determining the effects of d-brane instantons in
supersymmetric compactifications of Type II string theory to four dimensions. We describe …

A bstract The role of the\(\overline {\mathrm {D} 3}\) brane in providing de Sitter vacua with
spontaneously broken supersymmetry in the KKLT construction is clarified. The first step in …

We subject the phenomenologically successful large volume scenario of hep-th/0502058 to
a first consistency check in string theory. In particular, we consider whether the expansion of …

A bstract The Kalb-Ramond field is an antisymmetric, rank-two tensor field which most
notably appears in the context of string theory, but has largely been unexplored in the …
