D-brane Moduli Spaces and Superpotentials in a Two-Parameter Model
Marco Baumgartl, Ilka Brunner, Daniel Plencner
We study D2-branes on the K3-fibration P^4_(11222)[8] using matrix factorizations at the Landau-Ginzburg point and analyze their moduli space and superpotentials in detail. We find…
D-brane Superpotentials: Geometric and Worldsheet Approaches
Marco Baumgartl, Ilka Brunner, Masoud Soroush
From the worldsheet perspective, the superpotential on a D-brane wrapping internal cycles of a Calabi-Yau manifold is given as a generating functional for disk correlation function…
Backgrounds in Boundary String Field Theory
M. Baumgartl
We study the role of closed string backgrounds in boundary string field theory. Background independence requires the introduction of dual boundary fields, which are reminiscent of…
Moduli Webs and Superpotentials for Five-Branes
Marco Baumgartl, Simon Wood
We investigate the one-parameter Calabi-Yau models and identify families of D5-branes which are associated to lines embedded in these manifolds. The moduli spaces are given by sets…
On the Correspondence of Open and Closed Strings
Marco Baumgartl
This thesis investigates correspondences between open and closed strings. This is done on the level of coupled open-closed moduli spaces and from a string field theoretic point of…
Open-Closed String Correspondence in Open String Field Theory
Marco Baumgartl, Ivo Sachs
We address the problem of describing different closed string backgrounds in background independent open string field theory: A shift in the closed string background corresponds to…
