SUMMARY:GRASS Seminar: 'Electric-magnetic duality of dyonic Kerr-Newman-NUT-AdS spacetimes'
DESCRIPTION:GRASS (GRAvity\, Supergravity & Superstrings) Seminar \nSpeaker: Cristóbal Andrés Corral (Universidad Adolfo Ibáñez\, Chle) \nVenue & Time: Red Room / 15:00 \nAbstract: We discuss the (anti-)self-duality conditions under which the electric and magnetic parts of the conserved charges of the dyonic Kerr-Newman-NUT-AdS solution become equivalent. Within a holographic framework\, the stress tensor and the boundary Cotton tensor are computed from the electric/magnetic content of the Weyl tensor. The holographic stress tensor/Cotton tensor duality is recovered along the (anti-)self-dual curve in parameter space. We show that the latter not only implies a duality relation for the mass but also for the angular momentum.  The partition function is computed to first order in the saddle-point approximation and a BPS bound is obtained. The ground state of the theory is enlarged to all the (anti-)self-dual configurations when the SO(4) and U(1) Pontryagin densities are introduced. We demonstrate this at the level of the action and variations thereof.
