Giant Tachyons in the Landscape
Iosif Bena, Mariana Graña, Stanislav Kuperstein +1
We study the dynamics of localized and fully backreacting anti-D3 branes at the tip of the Klebanov-Strassler geometry. We use a non-supersymmetric version of the Polchinski-Strass…
M-theory moduli spaces and torsion-free structures
Mariana Graña, C. S. Shahbazi
Motivated by the description of M-theory compactifications to four-dimensions given by Exceptional Generalized Geometry, we propose a way to geometrize the M-theory…
Quantum Corrections in String Compactifications on SU(3) Structure Geometries
Mariana Grana, Jan Louis, Ulrich Theis +1
We investigate quantum corrections to the classical four-dimensional low-energy effective action of type II string theory compactified on SU(3) structure geometries. Various method…
Spin(7)-manifolds in compactifications to four dimensions
Mariana Graña, C. S. Shahbazi, Marco Zambon
We describe off-shell M-theory compactifications down to four dimensions in terms of eight-dimensional manifolds equipped with a topological -structure. Mo…
Tachyonic Anti-M2 Branes
Iosif Bena, Mariana Graña, Stanislav Kuperstein +1
We study the dynamics of anti-M2 branes in a warped Stenzel solution with M2 charges dissolved in fluxes by taking into account their full backreaction on the geometry. The resulti…
