Perturbing the symmetric orbifold from the worldsheet
Marc-Antoine Fiset, Matthias R. Gaberdiel, Kiarash Naderi +1
The symmetric orbifold of is the analogue of free SYM in four dimensions, and its dual is described by a tensionless string propagating in ${\rm AdS}_3\times {\rm S}…
Superconformal algebras for generalized Spin(7) and G connected sums
Marc-Antoine Fiset, Mateo Galdeano
Worldsheet string theory compactified on exceptional holomony manifolds is revisited following arXiv:1809.06376, where aspects of the chiral symmetry were described for the case wh…
Deformed Shatashvili-Vafa algebra for superstrings on AdS
Marc-Antoine Fiset, Matthias R. Gaberdiel
String backgrounds of the form where denotes -dimensional Minkowski space while is a -dimensional G-manifold,…
SW(3/2,2) subsymmetry in G, Spin(7) and N=2 CFTs
Marc-Antoine Fiset
Spectral flow, spacetime supersymmetry, topological twists, chiral primaries related to marginal deformations, mirror symmetry: these are important consequences of the worldsheet N…
G-structures and Superstrings from the Worldsheet
Marc-Antoine Fiset
-structures, where is a Lie group, are a uniform characterisation of many differential geometric structures of interest in supersymmetric compactificatio…
Superconformal algebras for twisted connected sums and mirror symmetry
Marc-Antoine Fiset
We realise the Shatashvili-Vafa superconformal algebra for string compactifications by combining Odake and free conformal algebras following closely the recent mathematical c…
-structure symmetries and anomalies in non-linear -models
Xenia de la Ossa, Marc-Antoine Fiset
A new symmetry of supersymmetric non-linear -models in two dimensions with Fermi and mass sectors is introduced. It is a generalisation of the so-called special holonomy…
Marginal deformations of heterotic sigma models
Marc-Antoine Fiset, Callum Quigley, Eirik Eik Svanes
Recently, the infinitesimal moduli space of heterotic compactifications was described in supergravity and related to the cohomology of a target space differential. In this pa…
Bounding the Heat Trace of a Calabi-Yau Manifold
Marc-Antoine Fiset, Johannes Walcher
The SCHOK bound states that the number of marginal deformations of certain two-dimensional conformal field theories is bounded linearly from above by the number of relevant operato…
Supersymmetric infinite wells and coherent states
Marc-Antoine Fiset, Véronique Hussin
Gaussian Klauder coherent states are discussed in the context of the infinite well quantum model, otherwise known as the particle in a box. A supersymmetric partner system is also…
Equivalent sets of coherent states of the 1D infinite square well and properties
Marc-Antoine Fiset, Véronique Hussin
We prove the equivalence (under some conditions) of two sets of coherent states built for the one-dimensional infinite square well: the so-called generalized and Gaussian Klauder c…
