Today’s Image of the Week comes from Mapping trilobite state signatures in atomic hydrogen by Jesús Pérez-Ríos, Matthew T Eiles and Chris H Greene. In their Letter the researchers study the spectroscopy of single Rydberg excitations to a trilobite state (can you see where the name comes from?) in a high density ultracold environment. These states have very short lifetimes and large electric dipoles.JPhysB is currently in the process of publishing a Special Issue on Rydberg Atomic Physics if you want to learn more about Rydberg states of all kinds.
