Feynman Integrals in Dimensional Regularization and Extensions of Calabi-Yau Motives
Kilian Bönisch, Claude Duhr, Fabian Fischbach +2
We provide a comprehensive summary of concepts from Calabi-Yau motives relevant to the computation of multi-loop Feynman integrals. From this we derive several consequences for mul…
Analytic Structure of all Loop Banana Amplitudes
Kilian Bönisch, Fabian Fischbach, Albrecht Klemm +2
Using the Gelfand-Kapranov-Zelevinsk\uı system for the primitive cohomology of an infinite series of complete intersection Calabi-Yau manifolds, whose dimension is the loop order m…
Lost Chapters in CHL Black Holes: Untwisted Quarter-BPS Dyons in the Model
Fabian Fischbach, Albrecht Klemm, Christoph Nega
Motivated by recent advances in Donaldson-Thomas theory, four-dimensional string-string duality is examined in a reduced rank theory on a less studied BPS sector. I…
WKB Method and Quantum Periods beyond Genus One
Fabian Fischbach, Albrecht Klemm, Christoph Nega
We extend topological string methods in order to perform WKB approximations for quantum mechanical problems with higher order potentials efficiently. This requires techniques for t…
