Non-perturbative SQCD Superpotentials from String Instantons
Nikolas Akerblom, Ralph Blumenhagen, Dieter Lust +2
The Affleck-Dine-Seiberg instanton generated superpotential for SQCD with Nf=Nc-1 flavours is explicitly derived from a local model of engineered intersecting D6-branes with a sing…
Adding flavour to the Polchinski-Strassler background
Riccardo Apreda, Johanna Erdmenger, Dieter Lust +1
As an extension of holography with flavour, we analyze in detail the embedding of a D7-brane probe into the Polchinski-Strassler gravity background, in which the breaking of confor…
Four-dimensional String Compactifications with D-Branes, Orientifolds and Fluxes
Ralph Blumenhagen, Boris Kors, Dieter Lust +1
This review article provides a pedagogical introduction into various classes of chiral string compactifications to four dimensions with D-branes and fluxes. The main concern is to…
Topological twisting of conformal supercharges
Jeong-Hyuck Park, Dimitrios Tsimpis
Putting a twisted version of N=4 super Yang-Mills on a curved four-dimensional manifold generically breaks all conformal supersymmetries. In the special case where the four-manifol…
Quantum Hall Effect on the Flag Manifold F_2
Mohammed Daoud, Ahmed Jellal
The Landau problem on the flag manifold is analyzed from an algebraic point of view. The involved magnetic background is induced by two U(1) abe…
Deformations of calibrated D-branes in flux generalized complex manifolds
Paul Koerber, Luca Martucci
We study massless deformations of generalized calibrated cycles, which describe, in the language of generalized complex geometry, supersymmetric D-branes in N=1 supersymmetric comp…
