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…
