 <p>The formal abstract follows but, in a paragraph, it's about what happens when many electrons interact together in a way where their 'quantumness' is important. It turns out that many weird and wonderful things can happen. Alas we, quantum physicists, don't have great mathematical tools to describe these things. Trying to fix that is what this thesis is about.
