Time-reversal symmetric hierarchy of fractional incompressible liquids

ORAL

Abstract

In this talk I shall establish a hierarchical construction for a class of BF theories and present it as a candidate topological field theory to describe fractional topological insulators in 2D. The structure of the K matrix and the universal properties that it describes will be discussed, and the properties of the time-reversal symmetric edge theory will be derived via the bulk-edge correspondence.
