Hybrid systems of laser-cooled trapped ions and ultracold atoms combined in a single experimental setup have recently emerged as a new platform for fundamental research in quantum physics [1]. Reaching ultracold s-wave quantum regime is one of the most important challenges in this field at the moment. I will discuss possible solutions to this problem by using ion-atom mixtures with the large ion/atom mass ratio [2] as well as using a specific type of homonuclear S-state Rydberg molecules with a small reduced mass to initialize and control ion-atom scattering events [3]. I will present how ab initio quantum chemistry calculations can support and guide quantum physics experiments. If time allows, I will present our theoretical proposals of novel systems for cold ion-atom experiments using ions or atoms other than alkali-metal or alkaline-earth-metal ones.
