You're absolutely correct. There are some nice papers by Potter, Vasseur et al. and Else and Nayak which illustrate your latter point in gory mathematical detail (they derive constraints from symmetry on symmetry protected topological phases and then use math to relate that to the sort of Floquet phases you can protect using symmetries). Of course, if you're actually Dominic Else, I defer to you... e: Hah, I commented without reading the article, this is the PRL publication of the Else and Nayak paper, with an added co-author, I had read the preprint a few months ago. The other paper good to read to enlighten oneself in this context is https://arxiv.org/abs/1510.04282 |
