The Chiral Ring
Sujay K. Ashok, Songyuan Li, Jan Troost
We study supersymmetric string theory backgrounds with Neveu-Schwarz-Neveu-Schwarz flux that are dual to superconformal theories on the bou…
The Topological Symmetric Orbifold
Songyuan Li, Jan Troost
We analyse topological orbifold conformal field theories on the symmetric product of a complex surface M. By exploiting the mathematics literature we show that a canonical quotient…
Twisted String Theory in Anti-de Sitter Space
Songyuan Li, Jan Troost
We construct a string theory in three-dimensional anti-de Sitter space-time that is independent of the boundary metric. It is a topologically twisted theory of quantum gravity. We…
Pure and Twisted Holography
Songyuan Li, Jan Troost
We analyse a simple example of a holographically dual pair in which we topologically twist both theories. The holography is based on the two-dimensional N=2 supersymmetric Liouvill…
Liouville Quantum Gravity
Songyuan Li, Nicolaos Toumbas, Jan Troost
We define a three-dimensional quantum theory of gravity as the holographic dual of the Liouville conformal field theory. The theory is consistent and unitary by definition. The cor…
Topological Gravity with Non-Compact Matter
Songyuan Li, Jan Troost
We couple twisted non-compact N=(2,2) supersymmetric models to topological gravity in two dimensions. We propose expressions for the genus zero correlation functions based on a Kad…
Twisted Massive Non-Compact Models
Songyuan Li, Jan Troost
We study interacting massive N=(2,2) supersymmetric field theories in two dimensions which arise from deforming conformal field theories with a continuous spectrum. Firstly, we def…
