Orientifolds of Gepner models without Kähler moduli
Miguel Morros, Johannes Walcher, Qi You
One of the main challenges in string theory Calabi-Yau compactifications to four dimensions is the stabilization of the massless complex structure and Kähler moduli. In type IIB s…

Anomaly-Free Spectra, Unimodular Lattices and 6D R-Symmetry Gauged Supergravity
Katrin Becker, Qi You
We study the classification problem for anomaly-free 6D supergravities with a gauged abelian R-symmetry and one tensor multiplet. We present eleven new models wi…

Tadpole conjecture in non-geometric backgrounds
Katrin Becker, Nathan Brady, Mariana Graña +3
Calabi-Yau compactifications have typically a large number of complex structure and/or Kähler moduli that have to be stabilised in phenomenologically-relevant vacua. The former ca…
