The D5-brane effective action and superpotential in N=1 compactifications
Thomas W. Grimm, Tae-Won Ha, Albrecht Klemm +1
The four-dimensional effective action for D5-branes in generic compact Calabi-Yau orientifolds is computed by performing a Kaluza-Klein reduction. The N=1 Kaehler potential, the su…
Integrability of the holomorphic anomaly equations
Babak Haghighat, Albrecht Klemm, Marco Rauch
We show that modularity and the gap condition make the holomorphic anomaly equation completely integrable for non-compact Calabi-Yau manifolds. This leads to a very efficient forma…
Seiberg-Witten theory and matrix models
Albrecht Klemm, Piotr Sułkowski
We derive a family of matrix models which encode solutions to the Seiberg-Witten theory in 4 and 5 dimensions. Partition functions of these matrix models are equal to the correspon…
Topological open strings on orbifolds
Vincent Bouchard, Albrecht Klemm, Marcos Marino +1
We use the remodeling approach to the B-model topological string in terms of recursion relations to study open string amplitudes at orbifold points. To this end, we clarify modular…
Noether-Lefschetz theory and the Yau-Zaslow conjecture
A. Klemm, D. Maulik, R. Pandharipande +1
The Yau-Zaslow conjecture determines the reduced genus 0 Gromov-Witten invariants of K3 surfaces in terms of the Dedekind eta function. Classical intersections of curves in the mod…
U(1) Mediation of Flux Supersymmetry Breaking
Thomas W. Grimm, Albrecht Klemm
We study the mediation of supersymmetry breaking triggered by background fluxes in Type II string compactifications with N=1 supersymmetry. The mediation arises due to an U(1) vect…
