New F-theory lifts

Andres Collinucci

In this note, a procedure is developed to explicitly construct non-trivial F-theory lifts of perturbative IIB orientifold models on Calabi-Yau complete intersections in toric varie…

Fano hypersurfaces and Calabi-Yau supermanifolds

Richard S. Garavuso, Maximilian Kreuzer, Alexander Noll

In this paper, we study the geometrical interpretations associated with Sethi's proposed general correspondence between N = 2 Landau-Ginzburg orbifolds with integral \hat{c} and N…

Near Flat Space limit of strings on AdS_4 x CP^3

M. Kreuzer, R. C. Rashkov, M. Schimpf

The non-linear nature of string theory on non-trivial backgrounds related to the AdS/CFT correspondence suggests to look for simplifications. Two such simplifications proved to be…

Four-modulus "Swiss Cheese" chiral models

Andres Collinucci, Maximilian Kreuzer, Christoph Mayrhofer +1

We study the 'Large Volume Scenario' on explicit, new, compact, four-modulus Calabi-Yau manifolds. We pay special attention to the chirality problem pointed out by Blumenhagen, Mos…

Meson supercurrents and the Meissner effect in the Sakai-Sugimoto model

Anton Rebhan, Andreas Schmitt, Stefan A. Stricker

The Sakai-Sugimoto model provides a holographic description for chiral symmetry breaking. We use this model to investigate chirally broken phases in an external magnetic field at f…

The elliptic genus from split flows and Donaldson-Thomas invariants

Andres Collinucci, Thomas Wyder

We analyze a mixed ensemble of low charge D4-D2-D0 brane states on the quintic and show that these can be successfully enumerated using attractor flow tree techniques and Donaldson…
