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…
Towards de Sitter from 10D
Jakob Moritz, Ander Retolaza, Alexander Westphal
Using a 10D lift of non-perturbative volume stabilization in type IIB string theory we study the limitations for obtaining de Sitter vacua. Based on this we find that the simplest…
Orientifolds of Warped Throats from Toric Calabi-Yau Singularities
Ander Retolaza, Angel Uranga
We study the complex deformations of orientifolds of D3-branes at toric CY singularities, using their description in terms of dimer diagrams. We describe orientifold quotients that…
De Sitter Uplift with Dynamical Susy Breaking
Ander Retolaza, Angel Uranga
We propose the use of D-brane realizations of Dynamical Supersymmetry Breaking (DSB) gauge sectors as sources of uplift in compactifications with moduli stabilization onto de Sitte…
D-brane Instantons as Gauge Instantons in Orientifolds of Chiral Quiver Theories
Sebastian Franco, Ander Retolaza, Angel Uranga
Systems of D3-branes at orientifold singularities can receive non-perturbative D-brane instanton corrections, inducing field theory operators in the 4d effective theory. In certain…
Bifid Throats for Axion Monodromy Inflation
Ander Retolaza, Angel M. Uranga, Alexander Westphal
We construct a simple explicit local geometry providing a `bifid throat' for 5-brane axion monodromy. A bifid throat is a throat that splits into two daughter throats in the IR, co…
Axion Monodromy Inflation on Warped Throats
Sebastian Franco, Daniele Galloni, Ander Retolaza +1
Recent models of axion monodromy inflation in string theory link the inflationary potential and the moduli stabilization potential. Realistic inflationary models require mechanisms…
Discrete gauge symmetries from (closed string) tachyon condensation
Mikel Berasaluce-González, Miguel Montero, Ander Retolaza +1
The study of discrete gauge symmetries in field theory and string theory is often carried out by embedding them into continuous symmetries. Many symmetries however do not seem to a…
