Everything you always wanted to know about non-Abelian quantum Hall states but were afraid to ask

The colloquium is about what happens when electrons are subjected to the following extreme conditions: strictly 2-dimensional geometry (flatland), ulta-low temperature (think mK) and very strong magnetic fields (think Tesla’s). It is known that electrons can then form quantum liquids known as fractional quantum Hall states. It is expected that they can form even more remarkable liquids known as non-Abelian quantum Hall states. I will address the many questions one may have: what is special about these states? – why the name? – how can they be detected? – can they be useful? – are they for real? – can they occur in atomic rather than electronic matter ? – when will we know?
