This article aims to review a selection of central topics and examples in logarithmic
conformal field theory. It begins with the remarkable observation of Cardy that the horizontal …

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 …

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 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× …

We construct a family of 3d quantum field theories $\mathcal T_ {n, k}^ A $ that conjecturally
provide a physical realization--and derived generalization--of non-semisimple mathematical …

For string theory on AdS 3 with pure NS-NS flux a complete set of DDF operators is
constructed, from which one can read off the symmetry algebra of the spacetime CFT …

A bstract The worldsheet string theory dual to free 4d\(\mathcal {N}\)= 4 super Yang-Mills
theory was recently proposed in [1]. It is described by a free field sigma model on the twistor …

A bstract The symmetric orbifold of 𝕋 4 is the analogue of free SYM in four dimensions, and
its dual is described by a tensionless string propagating in AdS 3× S 3× 𝕋 4. In this paper we …

A bstract In this work, we revisit the end-of-the-world (EOW) brane amplitudes in JT gravity
from a BF gauge theoretic perspective. Observing and identifying the correct group theoretic …

We review different exact approaches to string theory. In the context of the Green–Schwarz
superstring, we discuss the action in curved backgrounds and its supercoset formulation …
