Branes, fermions, and superspace dualities
Ander Retolaza, Jamie Rogers, Radu Tatar +1
We use the superspace formulation of supergravity in eleven and ten dimensions to compute fermion couplings on the M2-brane and on D-branes. In this formulation fermionic coupli…
Gaugino mass term for D-branes and Generalized Complex Geometry
Mariana Graña, Nicolas Kovensky, Ander Retolaza
We compute the four-dimensional gaugino mass for a Dp-brane extended in spacetime and wrapping a cycle on the internal geometry in a warped compactification with fluxes. Motivated…
Kähler moduli stabilization from ten dimensions
Iosif Bena, Mariana Graña, Nicolas Kovensky +1
We describe the back-reaction of gaugino condensates in supersymmetric AdS Type II String Theory compactifications with fluxes. We use generalized complex geometry to capture t…
On uplifts by warped anti-D3-branes
Jakob Moritz, Ander Retolaza, Alexander Westphal
In this note we outline the arguments against the ten-dimensional consistency of the simplest types of KKLT de Sitter vacua, as given in arXiv:1707.08678. We comment on parametriza…
Primordial Gravitational Waves and the Swampland
Mafalda Dias, Jonathan Frazer, Ander Retolaza +1
The swampland conjectures seek to distinguish effective field theories which can be consistently embedded in a theory of quantum gravity from those which can not (and are hence ref…
Pole N-flation
Mafalda Dias, Jonathan Frazer, Ander Retolaza +2
A second order pole in the scalar kinetic term can lead to a class of inflation models with universal predictions referred to as pole inflation or -attractors. While this kineti…
