Chern-Simons composite fermion theory of fractional Chern insulators
Chern-Simons composite fermion theory of fractional Chern insulators
We formulate a Chern-Simons composite fermion theory for Fractional Chern Insulators (FCIs), whereby bare fermions are mapped into composite fermions coupled to a lattice Chern-Simons gauge theory. We apply this construction to a Chern insulator model on the kagome lattice and identify a rich structure of gapped topological phases characterized …
