Tracking the symmetries of -orbifold K3s within the Mathieu groups
Kasia Budzik, Anne Taormina, Mara Ungureanu +2
For -orbifold limits of K3, we provide a counterpart to the extensive studies by Nikulin and others of the geometry and symmetries of classical Kummer surfaces. In par…
Asymmetric Orbifolds, Rank Reduction and Heterotic Islands
Gerardo Aldazabal, Eduardo Andrés, Anamaría Font +2
We consider toroidal asymmetric orbifolds of the heterotic string preserving all 16 supercharges, developing a general formalism to study components of the moduli space characteriz…
Minimally Extended Current Algebras of Toroidal Conformal Field Theories
Hans Jockers, Maik Sarve, Ida G. Zadeh
It is well-known that families of two-dimensional toroidal conformal field theories possess a dense subset of rational toroidal conformal field theories, which makes such families…
Ensemble Averages of Orbifold Classes of Narain CFTs
Stefan Forste, Hans Jockers, Joshua Kames-King +2
In this work we study families of orbifolds of toroidal conformal field theories based on both factorizable and non-factorizable target space tori. For these classes…
