(Anti-)Brane backreaction beyond perturbation theory
Johan Blåbäck, Ulf H. Danielsson, Daniel Junghans +3
We improve on the understanding of the backreaction of anti-D6-branes in a flux background that is mutually BPS with D6-branes. This setup is analogous to the study of the backreac…
The problematic backreaction of SUSY-breaking branes
Johan Blåbäck, Ulf H. Danielsson, Daniel Junghans +3
In this paper we investigate the localisation of SUSY-breaking branes which, in the smeared approximation, support specific non-BPS vacua. We show, for a wide class of boundary con…
Effects of Nonlinear Dispersion Relations on Non-Gaussianities
Amjad Ashoorioon, Diego Chialva, Ulf Danielsson
We investigate the effect of non-linear dispersion relations on the bispectrum. In particular, we study the case were the modified relations do not violate the WKB condition at ear…
De Sitter hunting in a classical landscape
Ulf H. Danielsson, Sheikh S. Haque, Paul Koerber +3
We elaborate on the construction of de Sitter solutions from IIA orientifolds of SU(3)-structure manifolds that solve the 10-dimensional equations of motion at tree-level in the ap…
