Inflation near a metastable de Sitter vacuum from moduli stabilisation
Ignatios Antoniadis, Osmin Lacombe, George K. Leontaris
We study the cosmological properties of a metastable de Sitter vacuum obtained recently in the framework of type IIB flux compactifications in the presence of three D7-brane stacks…
Note on supersymmetric Dirac-Born-Infeld action with Fayet-Iliopoulos term
Ignatios Antoniadis, Hongliang Jiang, Osmin Lacombe
We study the Dirac-Born-Infeld (DBI) action with one linear and one non-linear supersymmetry in the presence of a constant Fayet-Iliopoulos (FI) D-term added explicitly or through…
Supersymmetry Deformations, Electromagnetic Duality and Dirac-Born-Infeld Actions
Ignatios Antoniadis, Hongliang Jiang, Osmin Lacombe
We study the general deformation of supersymmetry transformations of a vector multiplet that forms a (constant) triplet under the R-symmetry corresponding to…
Imprints of relativistic effects on the asymmetry of the halo cross-correlation function: from linear to non-linear scales
Michel-Andrès Breton, Yann Rasera, Atsushi Taruya +2
The apparent distribution of large-scale structures in the universe is sensitive to the velocity/potential of the sources as well as the potential along the line-of-sight through t…
