Abstract: I will discuss a novel approach for obtaining the Euclidean on-shell action of a large class of known (and still to be found) solutions of 5d gauged supergravity. The geometries in question include multi-center solutions: black holes, black rings, black lenses, topological solitons, …. In the ungauged limit results match known on-shell actions of explicit flat space muli-center geometries. I will discuss the localization procedure including subtleties concerning holographic renormalization, and dealing with the non-trivial topology of the gauge fields due to CS terms in 5d. Finally, I will mention intriguing relations to various “volumes” found in the equivariant localization literature.
A recent perspective led by ICN2 researchers highlights the need for more rigorous strategies in surface area normalisation when comparing electrocatalyst materials. This approach could be key to improving clean energy and renewable fuel technologies.
