Extremal Bundles on Calabi-Yau Threefolds
Peng Gao, Yang-Hui He, Shing-Tung Yau
We study constructions of stable holomorphic vector bundles on Calabi-Yau threefolds, especially those with exact anomaly cancellation which we call extremal. By going through the…
Geodesics on Calabi-Yau manifolds and winding states in nonlinear sigma models
Peng Gao, Michael R. Douglas
We conjecture that a non-flat -real-dimensional compact Calabi-Yau manifold, such as a quintic hypersurface with D=6, or a K3 manifold with D=4, has locally length minimizing cl…
Fermionic Coset, Critical Level W^(2)_4-Algebra and Higher Spins
Thomas Creutzig, Peng Gao, Andrew R. Linshaw
The fermionic coset is a limit of the pure spinor formulation of the AdS5xS5 sigma model as well as a limit of a nonlinear topological A-model, introduced by Berkovits. We study th…
Minimal surfaces in AdS space and Integrable systems
Benjamin A. Burrington, Peng Gao
We consider the Pohlmeyer reduction for spacelike minimal area worldsheets in AdS. The Lax pair for the reduced theory is found, and written entirely in terms of the …
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…
Topological wave functions and the 4D-5D lift
Peng Gao, Boris Pioline
We revisit the holomorphic anomaly equations satisfied by the topological string amplitude from the perspective of the 4D-5D lift, in the context of ''magic'' N=2 supergravity theo…
