| From Single Atoms to Solids - Quantum Chemistry in Solid State Physics |
| Speaker: | Paul Tiwald (TU Wien) |
| Abstract: | I will give an introduction to quantum chemistry methods and their application to solid state and surface physics within the embedded cluster approach. Two topics currently under investigation will be presented. The first topic is the F-center in Lithium Fluoride (LiF), a point defect giving rise to bound electronic states. The second topic is the interaction dynamics and the charge transfer of a proton approaching a LiF surface. |

| (Entanglement) Entropy in three-dimensional higher spin theories |
| Speaker: | Juan Jottar (Amsterdam U.) |
| Abstract: | A holographic correspondence has been recently developed between higher spin theories in AdS_3 and (1+1)-dimensional CFTs with extended symmetries. In this framework, black hole solutions in the bulk theory are dual to thermal equilibrium states with non-trivial higher spin charges and chemical potentials. We discuss the calculation of the higher spin black hole entropy from an appropriate Euclidean variational principle, and provide a generalization of the Cardy entropy formula for these setups. Additionally, we present a proposal to compute entanglement entropy in the dual CFTs via holography, thus extending the Ryu-Takayanagi prescription to higher spin theories in AdS_3.
