Type II/F-theory Superpotentials with Several Deformations and N=1 Mirror Symmetry
Murad Alim, Michael Hecht, Hans Jockers +3
We present a detailed study of D-brane superpotentials depending on several open and closed-string deformations. The relative cohomology group associated with the brane defines a g…
Relative periods and open-string integer invariants for a compact Calabi-Yau hypersurface
Hans Jockers, Masoud Soroush
In this work we compute relative periods for B-branes, realized in terms of divisors in a compact Calabi-Yau hypersurface, by means of direct integration. Although we exemplify the…
Tachyon Condensation on the Elliptic Curve
S. Govindarajan, H. Jockers, W. Lerche +1
We use the framework of matrix factorizations to study topological B-type D-branes on the cubic curve. Specifically, we elucidate how the brane RR charges are encoded in the matrix…
The effective action of D-branes in Calabi-Yau orientifold compactifications
Hans Jockers
In this review article we study type IIB superstring compactifications in the presence of space-time filling D-branes while preserving N=1 supersymmetry in the effective four-dimen…
The effective action of D7-branes in N=1 Calabi-Yau orientifolds
Hans Jockers, Jan Louis
Using a Kaluza-Klein reduction of the Dirac-Born-Infeld and Chern-Simons action we compute the four dimensional N=1 effective action for the massless modes of a D7-brane which is w…
Soft Supersymmetry Breaking in Calabi-Yau Orientifolds with D-branes and Fluxes
Mariana Grana, Thomas W. Grimm, Hans Jockers +1
In this paper we compute the N=1 effective low energy action for a stack of N space-time filling D3-branes in generic type IIB Calabi-Yau orientifolds with non-trivial background f…
