Abstract: I will describe recent work on the boundary interpretation of orbits around an AdS black hole. When the orbits are far away from the black hole, these orbits describe heavy-light double-twist operators in the boundary CFT. I will discuss how the dimensions of these operators can be computed exactly in terms of quasinormal modes in the bulk, using techniques from supersymmetric gauge theory. I will also explain how these results are related to the concept of quantum scars, which are eigenstates that do not obey the eigenstate thermalisation hypothesis.
