A class of Calabi-Yau threefolds as manifolds of SU(2) structure
Michael B. Schulz
A class of abelian fibered Calabi-Yau threefolds X_{m,n} is shown yield SU(2) structure, in addition to the standard SU(3) holonomy. Compactification of type II string theory on a…
M-theory/type IIA duality and K3 in the Gibbons-Hawking approximation
Michael B. Schulz, Elliott F. Tammaro
We review the geometry of K3 surfaces and then describe this geometry from the point of view of an approximate metric of Gibbons-Hawking form. This metric arises from the M-theory…
T-folds, doubled geometry, and the SU(2) WZW model
Michael B. Schulz
The SU(2) WZW model at large level N can be interpreted semiclassically as string theory on S^3 with N units of Neveu-Schwarz H-flux. While globally geometric, the model neverthele…
Moduli Stabilization from Fluxes
Michael B. Schulz
A brief overview of hep-th/0201028 prepared for NATO Advanced Study Institute and EC Summer School on Progress in String, Field and Particle Theory, Cargese, Corsica, France, 25 Ju…
Abelian Fibrations, String Junctions, and Flux/Geometry Duality
Ron Donagi, Peng Gao, Michael B. Schulz
In previous work, it was argued that the type IIB T^6/Z_2 orientifold with a choice of flux preserving N=2 supersymmetry is dual to a class of purely geometric type IIA compactific…
Torsion and Supersymmetry Breaking
Albion Lawrence, Tobias Sander, Michael B. Schulz +1
We identify the auxiliary fields in the hypermultiplets of type IIB string theory compactified on a Calabi-Yau manifold, using a combination of worldsheet and supergravity techniqu…
