Originating Calendar Physics - Condensed Matter Seminar
The same bulk two-dimensional topological phase can have multiple distinct, fully-chiral edge phases. This can occur in the integer quantum Hall states at $\nu=8$ and $12$, with experimentally-testable consequences. It can also occur in Abelian fractional quantum Hall states, as well, with the simplest examples being at $\nu=8/7, 8/15, 16/5$. I will give a general criterion for the existence of multiple distinct chiral edge phases for the same bulk phase and discuss experimental consequences.
