Joint Seminar

This a joint online video seminar series on theoretical and mathematical physics organized together by the ASC and the universities of Heidelberg and Vienna via a BigBlueButton interface.

It will take place on Mondays at 15:15.

If you are interested to participate, please send an email toIlka Brunner.

26.10. Theo Johnson-Freyd (Perimeter) "3+1d topological orders with (only) an emergent fermion"
Abstract: There are exactly two bosonic 3+1d topological orders whose only nontrivial quasiparticle is an emergent fermion (and exactly one whose only nontrivial quasiparticle is an emergent boson). I will explain the meaning of this sentence: I will explain what a "3+1d topological order" is, and how I know that these are the complete list. Time permitting, I will tell you some details about these specific topological orders, and say what this classification has to do with "minimal modular extensions".
