hear and speak German in my Hamburg accent in Queensland. I also want to thank all others who are part of the atom optics group at Swinburne, mainly Dr. Alexander Akulshin and Prof. Russell McLean, for helping out whenever I needed a tool, advice or just another hand. Mark Kivinen I want to thank “in triplicate” for his great workshop work and Sharon Jesson I want to thank for all the fights with the administration that I didn’t have to fight. Now, more private thanks go to my friends Craig Lincoln and Ruth Plathe. It was great fun sharing a flat with Craig, and I could always count on Ruth to brighten my mood with her jokes. I also thank Heath who taught me a lot about the Australian culture and way-of-life. There are more people to thank: Dru, Craig and Grant, Jürgen and Holger, Grainne, Wayne (Rowlands), Wayne and Bob, Saeed and probably a dozen more who I should mention. I thank all of you for making my time overseas so enjoyable. On the Hannover side, the first thanks are reserved for Prof. Gerhard Birkl and Prof. Wolfgang Ertmer. They allowed me to work with them in Gerhard’s group as an exchange student, and made it possible for me to split my work between Australia and Germany. I would like to thank all my colleagues of the group A6 in Hannover. First Dr. Rainer Dumke, who introduced me to the system there and whose dry humour you can’t forget. Next is André Lengwenus with whom I enjoyed working during my first time in Hannover: you are doing better work than you admit to yourself. Dr. Tobias Müther I would like to thank not only for his vast knowledge on everything and the discussions we had, but also for his work in the lab, although our overlap there was rather small. Without him, the successes of the experiment would be unthinkable. I would also like to thank Johanna Nes and Anna-Lena Gehrmann, the first “women only” crew I have ever seen “man” an experiment. Very special thanks go to Dr. Michael Volk. Just like I had my flat mate vi
Chapter 0: Acknowledgements in the neighbouring lab at Swinburne, I had a friend and former flat mate at the neighbouring optical table in Hannover. I enjoyed the smoking and later the non-smoking breaks we had together. Furthermore I want to thank Dr. Norbert Herschbach and Dr. Peter Spoden for their encouraging words whenever I felt a bit disheartened, and Sascha Drenkelforth. And of course thanks go to all other group members who I didn’t name here; I wish you all the best for the future. I also thank my parents for all they have done and for all their support. Even though this is now the end of my list, the most important person in my life has not been thanked yet. Nicole, I love you. I have learnt that I never want to be away from you so far and for so long. vii
