Pair-Correlation Effects in Many-Body Systems

Abstract

While pursuing a Ph.D. in the Mathematical bioPhysics Group in Göttingen I got acquainted with many great people, who have contributed in their own way to this work, and to the person I have become. It remains a difficult task to acknowledge all of these people with concise wording, and therefore I consider my attempt below also far from complete.First and foremost I thank my supervisor Aljaž Godec. I can say with great confidence that I could not have gotten a better supervisor. His office door has always been open for a discussion, a coffee, or a good Chuck Norris fact. Without his guidance, and constant desire for a deeper understanding, I would not have been able to produce the work presented in this thesis. The way Aljaž thinks in terms of inequalities and counterexamples has been of great influence on my way of thinking. I also thank Aljaž's family who has shown great hospitality to me.Secondly, I would like to thank my colleagues -those in the past and present -in the Mathematical bioPhysics Group. Alessio Lapolla and David Hartich were the first two colleagues I met, and I thank you both for your kindness and inspiring work attitude. Alessio convinced me to join his sports wrestling courses, which were a lot of fun, despite his superior strength. With David and his family I share many warm memories, and the visit to Esslingen was a highlight that hopefully will soon take place again. Together with Maximilian Vossel I started my doctorate. Being the barista in our group, he has made many delicious espressos, and I thank you for your thoughtfulness and for the great moments we share. I thank Cai Dieball for his sharp questions, fruitful discussions, dry humor, and the rounds of tennis we played during the summer. With Janik Schüttler I had many enjoyable moments on the running track, where he often pushed me to do an extra round. I thank you for your friendliness and positive spirit, hopefully we can once meet again in Cambridge. Finally, I thank Rick Bebon and Gerrit Wellecke for being such pleasant colleagues, who are always open to a discussion. Rick has extensively read every chapter of my thesis, and provided me with great feedback. All in all, I am thankful for my colleagues who made/make the Mathematical bioPhysics Group a great place to work. V Within the Theoretical and Computational Biophysics department there were/are also many colleagues to thank. Special thanks go to Lars Bock, Sara Gabrielli, Gabor Nagy, Florian Leidner, Wojciech Kopec, and Peleg Sapir who have been thoughtful, friendly, and open to me. It was a pleasure to have lunch with you, meet for leisure time, or to have a little chat in the office. I thank Ansgar Esztermann and Martin Fechner for teaching me the ins and outs of computer cluster usage, which I initially did not use correctly. Furthermore, I thank Eveline Heinemann, Stefanie Teichmann, and Petra Kellers for the administrative assistance and their fast support during times I was rather late with my conference applications. Finally, I would like to thank Helmut Grubmüller ...
