Research subject:
The principal goal of our experiments is to study how chemical reactions take place at lowest temperatures. The classical concept predicts that approaching T = 0 K, that is, zero velocity is equivalent to a standstill of any dynamics. On the one hand, deviations can be expected, since the classical model breaks down in a regime where particle-wave dualism gains importance. Ultimately, in the regime of lowest temperatures quantum effects dominate and chemistry is predicted to obey fundamentally different rules. As a consequence, quantum chemistry might allow controlling reactions and their pathways by external fields, since forces and related interactions become comparable to the kinetic energy. Our project is the first one where ions are and have been trapped by purely optical means. The next step is to investigate optically trapped ions embedded in a BEC of neutral atoms. Its aim is to overcome fundamental limitations set by micromotion when combining optical and radiofrequency-based trapping. The common ensemble is predicted to reach orders of magnitude lower temperatures than the current state- of-the-art. This will be exploited to study ultracold many-body physics, such as the predicted bound states of atoms surrounding an ion and the the formation of BaRb+ and BaLi+ in the ultimate quantum regime.

It might be beneficial, however is not a requirement, for candidates to already have an experimental background in ion or atom trapping.
The position is related to a PhD program established in collaboration with the University of British Columbia (UBC), Canada, potentially offering the possibility of an extended stay at the UBC in Vancouver. No tuition fees. The salary will be determined in accordance with TV-L E13 (starting at 50%, final level 75%).

Applications should include ollowing documents: a letter of motivation, a CV, a list of publications (if available), certificate of qualification for matriculation at the university (with grades) and transcripts of record, master/diploma certificate (with grades) and the contact details of at least two referees.
