- Abstract
- We construct the symmetric-gapped surface states of a fractional topological insulator with an electromagnetic theta angle theta(em) = pi/3 and a discrete Z(3) gauge field. They are the proper generalizations of the T-Pfaffian state and Pfaffian/antisemion state and feature an extended periodicity compared with their "integer" topological band insulator counterparts. We demonstrate that the surface states have the correct anomalies associated with time-reversal symmetry and charge conservation.
