Special Mathematical and Theoretical Physics Seminar: Renormalization group and the error-correction codes

Speaker Nima Lashkari (Purdue)
Date: 2/1/2021
Time: 1 p.m.
Location: via Zoom
Sponsor: The Math and Physics Departments
Event Type: Seminar/Symposium

I will argue that the real-space RG is an exact error correction code. We show that formulating both problems for an arbitrary von Neumann algebra involves linear maps called conditional expectations. We provide an intuitive picture for a conditional expectation and the set of states invariant under it.
