Black holes in string theory with duality twists

Understand

We consider 5D supersymmetric black holes in string theory compactifications that partially break supersymmetry.

• We compactify type IIB on $T^4$ and then further compactify on a circle with a duality twist to give Minkowski vacua preserving partial supersymmetry ($\mathcal{N}=6,4,2,0$) in five dimensions.
• The effective supergravity theory is given by a Scherk-Schwarz reduction with a Scherk-Schwarz supergravity potential on the moduli space, and the lift of this to string theory imposes a quantization condition on the mass parameters.
• In this theory, we study black holes with three charges that descend from various ten-dimensional brane configurations.
