Gaugino Condensation and Nonperturbative Superpotentials in Flux Compactifications
Lars Goerlich, Shamit Kachru, Prasanta K. Tripathy +1
There are two known sources of nonperturbative superpotentials for Kähler moduli in type IIB orientifolds, or F-theory compactifications on Calabi-Yau fourfolds, with flux: Euclide…

N=1 and non-supersymmetric open string theories in six and four space-time dimensions
Lars Goerlich
This thesis contains an introductory chapter on orbifolds. The following chapter explains the foundations of orientifolds. Chapters 4-7 present own research. In chapter 4 we quanti…

Supersymmetric Intersecting Branes on the Type IIA T^6/Z_4 orientifold
Ralph Blumenhagen, Lars Goerlich, Tassilo Ott
We study supersymmetric intersecting D6-branes wrapping 3-cycles in the Type IIA T^6/Z_4 orientifold background. As a new feature, the 3-cycles in this orbifold space arise both fr…
