Seminarium Optyczne

Isolating ions and atoms from the environment is essential for experiments, especially if we aim to study quantumeffects. For decades, this has been achieved by trapping ions with radiofrequency (rf) fields and neutral particles withoptical fields. We are trapping ions by the interaction with light and electrostatic fields, in absence of any rf-fields. Wetake our results as starting point for studying how to combine the advantages of optical trapping and ions.In the first part of the talk, we will focus on the basics of optically trapping ions. In the second talk we aim todemonstrate the prospects of our approach in the context of interaction and reaction at ultralow temperatures as ashowcase. Following the seminal work in other groups in hybrid traps, we embed optically trapped ions into quantumgases to reach lowest temperatures, circumventing the currently inevitable excess kinetic energy in hybrid traps, whereions are kept but also driven by rf-fields. It might permit to enter the temperature regime where quantum effects arepredicted to dominate.
