Black Holes, q-Deformed 2d Yang-Mills, and Non-perturbative Topological Strings

- M. Aganagic, H. Ooguri, N. Saulina, C. Vafa
- Physics
- 30 November 2004

We count the number of bound states of BPS black holes on local Calabi-Yau three-folds involving a Riemann surface of genus g. We show that the corresponding gauge theory on the brane reduces to a… Expand

Monodromies, Fluxes, and Compact Three-Generation F-theory GUTs

- J. Marsano, N. Saulina, Sakura Schafer-Nameki
- Physics
- 25 June 2009

We analyze constraints for embedding local SU(5) F-theory GUTs into consistent compactifications and construct explicit three-generation models based on the geometry of [1]. The key tool for studying… Expand

Compact F-theory GUTs with U(1)PQ

- J. Marsano, N. Saulina, Sakura Schäfer-Nameki
- Physics
- 1 December 2009

We construct semi-local and global realizations of SU(5) GUTs in F-theory that utilize a U(1)PQ symmetry to protect against dimension four proton decay. Symmetries of this type, which assign charges… Expand

Instabilities in heterotic M-theory induced by open membrane instantons

- G. Moore, G. Peradze, N. Saulina
- Physics
- 12 December 2000

Abstract We study the effective low energy supergravity of the strongly coupled heterotic string compactified on a Calabi–Yau 3-fold with generic E 8 × E 8 gauge bundle. We focus on the effective… Expand

Chern–Simons–Rozansky–Witten topological field theory

- A. Kapustin, N. Saulina
- Physics, Mathematics
- 9 April 2009

We construct and study a new topological field theory in three dimensions. It is a hybrid between Chern–Simons and Rozansky–Witten theory and can be regarded as a topologically-twisted version of the… Expand

Stringy instantons and quiver gauge theories

- B. Florea, S. Kachru, J. McGreevy, N. Saulina
- Physics
- 2 October 2006

We explore contributions to the 4D effective superpotential which arise from Euclidean D3 branes (''instantons'') that intersect space-filling D-branes. These effects can perturb the effective field… Expand

D-branes as defects in the Calabi-Yau crystal

- N. Saulina, C. Vafa
- Physics
- 29 April 2004

We define the notion of A-model Lagrangian D-branes as introducing defects in the Calabi-Yau crystal. The crystal melting in the presence of these defects reproduces all genus string amplitudes as… Expand

Branes, black holes and topological strings on toric Calabi-Yau manifolds

- M. Aganagic, D. Jafferis, N. Saulina
- Physics
- 19 December 2005

We develop means of computing exact degeneracies of BPS black holes on toric Calabi-Yau manifolds. We show that the gauge theory on the D4 branes wrapping ample divisors reduces to 2D q-deformed… Expand

Topological boundary conditions in abelian Chern-Simons theory

- A. Kapustin, N. Saulina
- Physics, Mathematics
- 3 August 2010

We study topological boundary conditions in abelian Chern-Simons theory and line operators confined to such boundaries. From the mathematical point of view, their relationships are described by a… Expand

F-theory Compactifications for Supersymmetric GUTs

- J. Marsano, N. Saulina, Sakura Schafer-Nameki
- Physics
- 27 April 2009

We construct a family of elliptically fibered Calabi-Yau four-folds Y_4 for F-theory compactifications that realize SU(5) GUTs in the low-energy limit. The three-fold base X_3 of these fibrations is… Expand
