From Dirac fermions to topological matter: a common thread in particle and condensed matter physics

Ever since the discovery of the Integer Quantum Hall Effect and the seminal theoretical papers by Thouless, Kohmoto, Nightingale and den Nijs, and by Haldane, the notion of topological materials has played a central role in condensed matter physics.  Surprisingly, topological materials are also ubiquitous in relativistic quantum field theories.

I describe how parallel developments in the two fields are related, and discuss my own work on the subject, old and recent.
