David Ing has submitted his PhD today with the title "On the application of theoretical multi-dimensional coherence spectroscopy techniques to discrete quantum systems". This is an exploration of the complexity of ultra-fast, multi-pulse spectroscopy, open-quantum systems theory, the interplay of coherence and decoherence and how to do a PhD remotely (eventually). Having spent far more time out of metropolitan Melbourne than in it, David has new found skills in self-motivation and diligence. With a 12 month stay at Ulm Universität and a series of stints living in Bendigo and commuting to Melbourne, David's german skills, his ability to get up well before sunrise and his knowledge of the V-line system have all progressed a long way from when he first joined the group as a fresh-faced 3rd year intrigued by non-Markovian processes. David's thesis involved numerical simulating a range of multi-dimensional spectroscopy setups, including working with some particularly nasty double-sided Feynman diagrams (or Feynagrams as he would call them). From David's work we now understand much more about how noise correlation length, coupling strength and orientation, and temperature can be studied with these advanced spectropic techniques. Whether its the natty suits or the blacksmith practice, David has always been our go to person when trying to explore the 18th and 19th centuries incognito.
