ℤ2 boundary twist fields and the moduli space of D-branes
Journal of High Energy Physics, 2018 We revisit the boundary conformal field theory of twist fields. Based on the equivalence between twisted bosons on a circle and the orbifold theory at the critical radius, we provide a bosonized representation of boundary twist fields and thus a free ...

4d/2d Correspondence: Instantons and W-Algebras [PDF]
, 2012 In this thesis, we study the 4d/2d correspondence of Alday-Gaiotto-Tachikawa, which relates the class of 4-dimensional N=2 gauge theories (theories of class S) to a 2-dimensional conformal field theory. The 4d gauge theories are obtained by compactifying

Type II string theory on Calabi-Yau manifolds with torsion and non-Abelian discrete gauge symmetries
Journal of High Energy Physics, 2017 We provide the first explicit example of Type IIB string theory compactification on a globally defined Calabi-Yau threefold with torsion which results in a four-dimensional effective theory with a non-Abelian discrete gauge symmetry. Our example is based

Superspace conformal field theory [PDF]
, 2013 Conformal sigma models and Wess?Zumino?Witten (WZW) models on coset superspaces provide important examples of logarithmic conformal field theories. They possess many applications to problems in string and condensed matter theory. We review recent results

Localization and Dualities in Three Dimensional Superconformal Field Theories [PDF]
, 2012 In this thesis we apply the technique of localization to three-dimensional N=2 superconformal field theories. We consider both theories which are exactly superconformal, and those which are believed to flow to nontrivial superconformal fixed points, for

Non-Abelian orbifolds in string theory [PDF]
, 2022 Two dimensional conformal field theories (CFT) play a key role in String theory, in particular they provide a suitable description of dynamics of the string in a given space-time.

Relation between spectra of Narain CFTs and properties of associated boolean functions
Journal of High Energy Physics, 2022 Recently, the construction of Narain CFT from a certain class of quantum error correcting codes has been discovered. In particular, the spectral gap of Narain CFT corresponds to the binary distance of the code, not the genuine Hamming distance.

Integrable flows between exact CFTs
Journal of High Energy Physics, 2017 We explicitly construct families of integrable σ-model actions smoothly inter-polating between exact CFTs. In the ultraviolet the theory is the direct product of two current algebras at levels k 1 and k 2.

T-duality invariant approaches to string theory [PDF]
, 2010 PhDThis thesis investigates the quantum properties of T-duality invariant formalisms of String Theory. We introduce and review duality invariant formalisms of String Theory including the Doubled Formalism.
