Topological Phases and Relativistic QFTs


The main aim is to revisit various known constructions in relativistic QFTs on the hep-th side of the community, from a new viewpoint of the symmetry protected topological phases, introduced by the cond-mat side of the community. The lectures are mostly about 温故知新, i.e. by warming-up the old to learn the new.

A hard-to-read handwritten notes are available. The notes are organized as follows:

Four hours at the CERN winter school 2018, on Feb 12-16, 2018, and four and a half hours at Rikkyo University, Feb 28, 2018.

In the actual lectures in CERN, I didn't have time to talk about the higher-form generalizations and the original lecture 4. Instead I prepared the lecture 5 in the morning of the last day and gave a talk on it instead.

The video recordings at CERN are available below: Lecture 1, Lecture 2, Lecture 3, Lecture 4
