Hodge Structures of Complex Multiplication Type from Rational Conformal Field Theories
Hans Jockers, Pyry Kuusela, Maik Sarve
Under certain assumptions, we show that unitary rational conformal field theories together with a certain generating set of Cardy boundary states in the associa…
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…
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…
Modular Calabi-Yau Fourfolds and Connections to M-Theory Fluxes
Hans Jockers, Sören Kotlewski, Pyry Kuusela
In this work, we study the local zeta functions of Calabi-Yau fourfolds. This is done by developing arithmetic deformation techniques to compute the factor of the zeta function tha…
