Research Abstract

We have created an ultra-cold atom-ion hybrid system using laser-cooled 40Ca+ ions and6Li atoms. To create the mixture, we have made laser diode systems to trap and cool ions and atoms. We successfully create the mixture by transporting atoms to the ion trap position by optical tweezers technique. We experimentally determined the elastic scattering cross-section between atoms and ions in a temperature range from 0.1 K to 3K.
