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…
