Non-Perturbative Corrections to 3d BPS Indices and Topological Strings
Hans Jockers
For a 3d gauged linear sigma model parametrized by a Kahler manifold X, the 3d BPS index defines a q-series that can be analytically continued in the Kahler modulus by standard met…
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…
On the Geometry of N=2 Minkowski Vacua of Gauged N=2 Supergravity Theories in Four Dimensions
Hans Jockers, Sören Kotlewski
Gauging isometries of four-dimensional N=2 supergravity theories yields an N=2 supersymmetric theory with a scalar potential. In this note, we study the well-known constraints for…
A Calabi-Yau-to-Curve Correspondence for Feynman Integrals
Hans Jockers, Sören Kotlewski, Pyry Kuusela +5
It has long been known that the maximal cut of the equal-mass four-loop banana integral is a period of a family of Calabi-Yau threefolds that depends on the kinematic variable $z=m…
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…
