Titre Dissecting Orbifolds with integrability and localisation
Résumé Type IIB string theory on AdS_5 x S^5 is integrable, which allows us to compute the spectrum of the dual CFT to extreme accuracy, even for non-BPS states. The arguably simplest deformation of this model is an orbifold projection, which generically breaks supersymmetry but retains integrability. This allows us to study AdS/CFT in systems with reduced supersymmetry. If we break supersymmetry completely, as for example in type 0B theory, tachyons come to haunt us, and their matching across AdS/CFT is quite puzzling. If we retain N=2 supersymmetry, the gauge theory is well behaved and extensively studied. However, the string theory side is lagging behind, so I raise the question whether recent localisation results can help us understand it better.
