Noncommutative Compactifications of Type I Strings on Tori with Magnetic Background Flux
Ralph Blumenhagen, Lars Goerlich, Boris Kors +1
We construct six- and four-dimensional toroidal compactifications of the Type I string with magnetic flux on the D-branes. The open strings in this background probe a noncommutativ…
Asymmetric Orbifolds, Noncommutative Geometry and Type I String Vacua
Ralph Blumenhagen, Lars Goerlich, Boris Kors +1
We investigate the D-brane contents of asymmetric orbifolds. Using T-duality we find that the consistent description of open strings in asymmetric orbifolds requires to turn on bac…
Supersymmetric 4D Orientifolds of Type IIA with D6-branes at Angles
Ralph Blumenhagen, Lars Goerlich, Boris Kors
We study a certain class of four-dimensional N=1 supersymmetric orientifolds for which the world-sheet parity transformation is combined with a complex conjugation in the compact d…
Supersymmetric Orientifolds in 6D with D-Branes at Angles
Ralph Blumenhagen, Lars Goerlich, Boris Kors
We study a new class of N=1 supersymmetric orientifolds in six space-time dimensions. The world-sheet parity transformation is combined with a permutation of the internal complex c…
