Laser-cooling of molecules in various charge states — •Robert Berger — Philipps-Universität Marburg, Germany

In this talk, I will discuss theoretical perspectives on laser cooling of diatomic and polyatomic molecules in different charge states, ranging from highly-charged cations [1] via neutrals [2-4] to monoanionic systems [5]. For heavy elemental radioactive systems, I will indicate the opportunities that open d-shells and f-shells provide in laser-cooling and address prospects for detecting violations of fundamental symmetries in these systems [1,2,6,7].
