A bstract We revisit the minimal tension (k= 1) string theory on AdS 3× S 3× 𝕋 4. We propose
a new free-field description of the worldsheet theory and show how localization of string …

A bstract We study string theory in three-dimensional Anti-de Sitter spacetime in the path
integral formalism. We derive expressions for generic spectrally-flowed near-boundary …

A bstract One of the few cases of AdS/CFT where both sides of the duality are under good
control relates tensionless k= 1 strings on AdS 3 to a two-dimensional symmetric product …

A bstract We study the spectrum generating operators (DDF operators) for bosonic strings
and superstrings in AdS 3× X with pure, generic NSNS flux. The dual CFT is conjectured to …

We revisit the minimal tension (k= 1) string theory on AdS3× S3× T4. We propose a new free-
field description of the worldsheet theory and show how localization of string amplitudes …

We study worldsheet sphere amplitudes, in the RNS formalism, in superstring theory on
$\text {AdS} _3\times X $ with pure NS-NS flux using the near-boundary approximation. By …

In this work, we calculate correlators of long strings on AdS3× S3× T4 with pure NS-NS flux.
We first construct physical vertex operators that correspond to long strings. Due to the GSO …

We study topological defect lines in the symmetric-product orbifolds $\mathrm {Sym}^ N (X) $
for a generic seed CFT $ X $. We focus on the defects which preserve the maximum of the …

We propose that string theory on ${\rm AdS} _3\times {\rm S}^ 3\times {\rm S}^ 3\times {\rm
S}^ 1$ with $\textit {two} $ units of NS-NS flux through each of the two $3 $-spheres is …

In this work, we calculate correlators of long strings on AdS $ _3\times $ S $^ 3\times $ T $^
4$ with pure NS-NS flux. We first construct physical vertex operators that correspond to long …
