| A no-hair theorem for non-isolated black holes |
| Speaker: | Norman Gürlebeck (Bremen) |
| Abstract: | In my talk, I prove a no-theorem for static and axially symmetric black holes surrounded by matter. More precisely, I will show that external fields do not induce multipole moments in such black holes that could be read off at infinity. The key ingredients in the proof is the source integral formalism, which will be introduced as well. It allows to define quasi-locally for each region in the spacetime its contribution to the asymptotically defined total multipole moments of that spacetime. |

| Entanglement entropy in a holographic model of the Kondo effect |
| Speaker: | Mario Flory (MPI Munich) |
| Abstract: | Starting from a holographic model of the Kondo effect recently proposed by Erdmenger et. al., i.e. of a magnetic impurity interacting with a strongly coupled system, I focus on the challenges of computing gravitational backreaction in this model, which demands a study of the Israel junction conditions. I present general results on these junction
conditions which may be relevant more generally in the AdS/boundary CFT correspondence. Furthermore, similar junction conditions for a bulk Chern-Simons field appearing in the holographic Kondo model are discussed. I then focus on the computation and interpretation of entanglement entropy in the holographic Kondo model. The holographic g-theorem will be discussed as well as a geometric construction that allows to reproduce results obtained by conformal perturbation
theory on the boundary.
