Massive Theta Lifts
Marcus Berg, Daniel Persson
We use Poincare series for massive Maass-Jacobi forms to define a "massive theta lift", and apply it to the examples of the constant function and the modular invariant j-function,…
BPS Algebras in 2D String Theory
Sarah M. Harrison, Natalie M. Paquette, Daniel Persson +1
We discuss a set of heterotic and type II string theory compactifications to 1+1 dimensions that are characterized by factorized internal worldsheet CFTs of the form $V_1\otimes \b…
Fun with
Sarah M. Harrison, Natalie M. Paquette, Daniel Persson +1
We study some special features of , the holomorphic superconformal field theory (SCFT) given by 24 chiral free fermions. We construct eight different Lie superalgebr…
Emergent Sasaki-Einstein geometry and AdS/CFT
Robert J. Berman, Tristan C. Collins, Daniel Persson
We consider supergravity in five-dimensional Anti-De Sitter space with minimal supersymmetry, encoded by a Sasaki-Einstein metric on a five-dimensional compact manifold $…
Dualities in CHL-Models
Daniel Persson, Roberto Volpato
We define a very general class of CHL-models associated with any string theory (bosonic or supersymmetric) compactified on an internal CFT C x T^d. We take the orbifold by a pair (…
BPS Algebras, Genus Zero, and the Heterotic Monster
Natalie M. Paquette, Daniel Persson, Roberto Volpato
In this note, we expand on some technical issues raised in \cite{PPV} by the authors, as well as providing a friendly introduction to and summary of our previous work. We construct…
