Non-perturbative topological string theory on compact Calabi-Yau 3-folds
Jie Gu, Amir-Kian Kashani-Poor, Albrecht Klemm +1
We obtain analytic and numerical results for the non-perturbative amplitudes of topological string theory on arbitrary, compact Calabi-Yau manifolds. Our approach is based on the t…
Quantum geometry, stability and modularity
Sergei Alexandrov, Soheyla Feyzbakhsh, Albrecht Klemm +2
By exploiting new mathematical relations between Pandharipande-Thomas (PT) invariants, closely related to Gopakumar-Vafa (GV) invariants, and rank 0 Donaldson-Thomas (DT) invariant…
The ice cone family and iterated integrals for Calabi-Yau varieties
Claude Duhr, Albrecht Klemm, Christoph Nega +1
We present for the first time fully analytic results for multi-loop equal-mass ice cone graphs in two dimensions. By analysing the leading singularities of these integrals, we find…
Topological Strings on Non-Commutative Resolutions
Sheldon Katz, Albrecht Klemm, Thorsten Schimannek +1
In this paper we propose a definition of torsion refined Gopakumar-Vafa (GV) invariants for Calabi-Yau threefolds with terminal nodal singularities that do not admit Kähler crepant…
Yangian-invariant fishnet integrals in 2 dimensions as volumes of Calabi-Yau varieties
Claude Duhr, Albrecht Klemm, Florian Loebbert +2
We argue that -loop Yangian-invariant fishnet integrals in 2 dimensions are connected to a family of Calabi-Yau -folds. The value of the integral can be computed from t…
Time reversal and invariance in Calabi-Yau compactifications
Kilian Bönisch, Mohamed Elmi, Amir-Kian Kashani-Poor +1
We revisit the question of time reversal and invariance in Calabi-Yau compactifications. We show that time reversal invariance is respected by quantum corrections to the prepo…
