We review some aspects of the dramatic consequences of supersymmetry breaking on
string vacua. In particular, we focus on the issue of vacuum stability in ten-dimensional string …

A bstract It was recently argued that string theory on AdS 3× S 3× 𝕋 4 with one unit (k= 1) of
NS-NS flux is exactly dual to the symmetric orbifold CFT Sym N (𝕋 4). In this paper we show …

A bstract Superstring theory on\({\mathrm {AdS}} _3\times {S}^ 3\times {\mathbb {T}}^ 4\) with
the smallest amount of NS-NS flux (“k= 1”) is shown to be dual to the spacetime CFT given …

The spectrum of superstrings on AdS3× S3× M 4 with pure NS-NS flux is analysed for the
background where the radius of the AdS space takes the minimal value (k= 1). Both for M 4 …

A bstract We investigate the proposed holographic duality between the TsT transformation of
IIB string theory on AdS 3×\(\mathcal {N}\) with NS-NS flux and a single-trace\(T\overline {T}\) …

A bstract We consider string theory on AdS 3× S 3× 𝕋 4 in the tensionless limit, with one unit
of NS-NS flux. This theory is conjectured to describe the symmetric product orbifold CFT. We …

A bstract We examine the question how string theory achieves a sum over bulk geometries
with fixed asymptotic boundary conditions. We discuss this problem with the help of the …

A bstract We employ the free field realisation of the\(\mathfrak {psu}{\left (1, 1\left|
2\right.\right)} _1\) world-sheet theory to constrain the correlators of string theory on AdS 3× …

A bstract We study AdS 3 x S 2 solutions in massive IIA that preserve small\(\mathcal
{N}\)=(4, 0) supersymmetry in terms of an SU (2)-structure on the remaining internal space …

We discuss in detail the 1+ 1-dimensional superconformal field theory dual to type II string
theory on AdS 3× S 3× T 4, emphasizing the string theoretic aspects of this duality. For one …
